Local DNS Settings: Map a Domain to a Local IP Address

Posted April 11, 2013 by Mark Wahl & filed under Quick Tips , Web Development , WordPress .

On occasion you may have reason to map a domain name to a specific IP address on an individual computer.  I find this most useful when developing locally so that I can use a website’s actual domain name but map it to the local dev version of the site.

Using a custom domain mapping is particularly important when developing with WordPress because the siteURL plays such a central role in creating links and resources in the WP structure. If you can use the actual domain during development, you’ll save yourself trouble later having to update the siteURL and any data that would have referenced the in-development domain.

Local DNS settings allow you to manage custom domain mappings to IP addresses of your choosing. These may be internal IPs within your local area network, or public IPs outside your network. These mappings are set up by editing the “Hosts” file on Windows or Mac systems. Here’s how:

Edit the Hosts File in Windows

1. Open the Hosts file in Notebook or some other simple text editor editor. Where is the hosts file you ask? Depends on your setup, but for most Windows systems the directory path should be something like

\\Windows\System32\drivers\etc\hosts

Depending on your security settings, you may need to open your text editor in administrator mode (‘run as administrator’) in order to save your edits.

2. At the top of the file there are instructions for how to use the file, all preceeded by the # comment tags.

3. Below this are the actual mappings. The first column contains the preferred IP destination, while the second column contains the domain to be mapped. The domains in the second column will resolve to the corresponding IPs in the first column. A few important points:

  • Naked domains and subdomains (i.e., www.) must be mapped separately.
  • You must use an IP address in the first column, not another domain name.
  • Use hashes to disable mappings temporarily

4. Once you’ve made your settings, save the file.

5. Open the Command Prompt and update your system’s DNS cache with the command:

ipconfig /flushdns

6. All browsers should now follow these mappings for the domains listed in this Hosts file.

Edit the Hosts File on a Mac OSX

1. Open Terminal and open the hosts file using the following command:

sudo nano /private/etc/hosts 

2. You may be asked to enter your administrator password. Go ahead and do that to continue.

3. The Hosts file will open. Much like the Windows version, there are instruction comments at the top, followed by the mappings. The first column contains the preferred IP destination, while the second column contains the domain to be mapped. The domains in the second column will resolve to the corresponding IPs in the first column.

4. Add your new mappings. Just as with the Windows version, keep in mind that:

5. When finished save your changes by pressing Control-o, then hit return to confirm the filename, then Control-x to close the Hosts file.

6. Lastly, update your DNS cache from Terminal using the command:

dscacheutil -flushcache

7. All browsers should now follow these mappings for the domains listed in this Hosts file.

How to point your domain name to an IP address

' src=

Updated: March 28, 2023

point domain name to ip address

If you’re building a self-hosted website, you need to  point your domain name to the public IP address of your web hosting .

If this step is not completed, when people type your website address into the address bar of the web browser and press the Enter key on their keyboard, they would not be able to open your website.

How to point your domain name to an IP address?

To point your domain name to the public IP address of your web hosting, you need to create an “A” record, which allows you to associate a hostname with an IPv4 address.

Normally you just need to create one or two A records: One for the naked domain (e.g. supereasy.com); another for the “www” version of your domain (e.g. www.supereasy.com).

Here’s the step-by-step guide:

To do it, you can use the name servers from your domain name registrar. This post will use NameSilo’s name servers as an example to show you how to point your domain name to an IP address:

  • Go to the official site of your domain name registrar (e.g. NameSilo.com ). Then sign in with your account. Normally you’ll be asked to create an account before you register a domain name.

assign domain name to local ip address

  • In the Manage DNS page, click  A  in the  Add/Edit a Resource Record  section to add an A record.

assign domain name to local ip address

It may take up to 15 minutes to completely process. Once it is completed, you can visit your website by entering www.yourdomain.com or just yourdomain.com .

How to run your own dns server on your local network.

Running your own DNS server is a great way to accelerate your network's responsiveness, reduce your reliance on public infrastructure, and benefit from extra functionality like hostname routing.

Quick Links

What is dns, why run your own dns, dns with dnsmasq, getting started, mapping hostnames to ips, testing your server, configuring your network.

Running your own DNS server is a great way to accelerate your network's responsiveness, reduce your reliance on public infrastructure, and benefit from extra functionality like hostname routing. Here's how to set up a DNS server on a Linux machine using Dnsmasq.

DNS is the system that translates a domain name like example.com to the numerical IP address of its server. This could look like

. Whenever you make a network request using a domain name, your system will perform a DNS lookup to determine the server address it should contact.

This adds an overhead to every request you make. Although your device will cache DNS responses, visits to new domains will incur a DNS round-trip before the actual request begins. This occurs at the level of the OS networking stack, invisible to you as the user.

ISPs usually run DNS servers. You're probably relying on your ISP's server if you're using default settings on your router and devices. Other public DNS servers are available from providers such as Cloudflare and Google .

Running your own DNS server gives you more control over your network. One common motivation is being able to configure network-level domain mappings, such as web-server to 192.168.0.101 . Configuring your router to use your DNS would result in any of your connected devices being able to access 192.168.0.101 via http://web-server .

Having your own DNS server lets you centralize settings into one location instead of applying them individually in /etc/hosts on each device. They'll apply to everything you connect to your network, including embedded hardware which provides no other way to customize its routing stack.

An in-house DNS server can also improve performance and provide an extra layer of resilience. Wide-scale DNS outages are not unheard of ; using a custom server with a long-lived cache for critical services you interact with could help you ride out downtime at your selected upstream provider.

Dnsmasq is a lightweight DNS server that's included with most Linux distributions. It's also refreshingly simple to configure.

Before starting out, it's worth thinking about what functionality you need your DNS server to provide. In this guide, we'll look at setting up Dnsmasq with local caching, some custom domain routes, and Google's 8.8.8.8 as our upstream DNS provider.

The routing flow will look like this:

  • Network router receives a request from one of your connected devices. The router will be configured to use the Dnsmasq host as its DNS server.
  • Dnsmasq will check whether it has a defined route for the domain name, such as web-server to 192.168.0.101 . If the request was for http: //web-server/example-page , it will send 192.168.0.101 back to the router.
  • When Dnsmasq has no matching route, it will forward the DNS request to Google's 8.8.8.8 , enabling resolution on the public internet. This ensures you can still reach the wider web when using your own DNS.

You won't need to make any config changes on your client devices. Everything behind your router will end up making DNS queries via Dnsmasq. However, it is worth noting that all popular desktop and mobile operating systems support setting a DNS server, so you could configure individual devices to use Dnsmasq without enabling it at the router level.

We'll assume you've already got a functioning Linux machine ready to host Dnsmasq. Dnsmasq is not particularly resource-intensive - if you've got few client devices, it will easily run on a Raspberry Pi.

Your host should have a static IP assigned. From hereon, the IP 192.168.0.1 refers to the Dnsmasq server.

Make sure Dnsmasq is installed:

# Assuming a Debian system

apt install dnsmasq

Dnsmasq's config file is usually located at /etc/dnsmasq.conf . This is pre-populated with initial settings. Some changes need to be made for Dnsmasq to work effectively in a local network scenario. Run sudo nano /etc/dnsmasq.conf to open the file, then use the Ctrl+W keyboard shortcut to find and uncomment the following lines:

#domain-needed

#bogus-priv

Remove the # character from the start of each line. Here's what these settings are enabling:

  • domain-needed - This stops Dnsmasq from forwarding local names without a domain part to the upstream DNS server. In our installation, it means example.com will be eligible for resolution via Google but example or web-server will not. It reserves dot-less names for your local network.
  • bogus-priv - Prevents forwarding DNS reverse-lookup queries to the upstream DNS server. It means internal IPs like 192.168.0.101 will never be exposed to Google. Not enabling this could unintentionally leak the architecture of your internal network to your upstream provider.

To set your upstream DNS server, add a new line to your config file:

server=8.8.8.8

server=4.4.4.4

This instructs Dnsmasq to forward unresolved queries to 8.8.8.8 . If that server's unavailable, 4.4.4.4 will be used instead. These addresses are the primary and secondary resolvers for Google's DNS service.

Next adjust the cache size. This defaults to a relatively low value of 150 cached requests. Increasing this will let Dnsmasq serve more lookups from the cache, reducing network latency. Find the cache-size line, uncomment it, and change its value:

cache-size=1000

Save and close the file now.

There are a few different ways to map hostnames to their IP addresses. The simplest is to add entries to your server's existing /etc/hosts file. Dnsmasq automatically loads the rules from this file as part of its default configuration.

Open /etc/hosts and add your routes to the bottom of the file. The IP address comes first, followed by the name to assign:

192.168.0.101 web-server

192.168.0.105 gateway.lan

These lines mean any request to http://web-server will be directed to 192.168.0.101 while http://gateway.lan will end up at 192.168.0.5 . Save and close the file when you've finished mapping your devices.

Restart Dnsmasq to apply all your changes:

sudo service dnsmasq restart

Check the server's running correctly:

sudo service dnsmasq status

You should see active (running) displayed in green. If you don't, check the log lines at the bottom of the status information to work out what's wrong.

Screenshot of running "service dnsmasq status" on a live server

Now you're ready to test your server. You can make manual DNS lookup attempts with the dig tool. You might need to install the dnsutils package first.

dig google.com @localhost

dig gateway.lan @localhost

Both of these commands should show an IP address in the ANSWER SECTION . In the case of gateway.lan , the result should be 192.168.0.5 according to the routing rule set up in /etc/hosts . The @localhost part of the commands instructs dig to query your local DNS server.

The final step is to configure your network router to make DNS lookups via your Dnsmasq server. The steps for this will vary depending on the routing equipment you're using.

Once you find the correct settings page, set your server's IP ( 192.168.0.1 in this guide) as the router's primary DNS server. It's a good idea to configure a public DNS provider, such as Google's 8.8.8.8 , as the secondary server. This ensures you'll still have internet access if your DNS server crashes and goes offline.

Now all the devices connected to your router will make DNS queries via your Dnsmasq instance. They'll be able to reach your devices by their assigned names, such as web-server and gateway.lan , and benefit from network-level DNS caching.

DNS is an intricate topic but Dnsmasq makes it easy to get a basic server operational. There are many more settings which you can explore once you've got the core functionality working. These let you filter queries, manage relays and proxies, run scripts when events occur, and set up other kinds of DNS record such as MX results for mail servers.

Dnsmasq doesn't usually need much manual intervention once it's live. You can monitor logs using service dnsmasq status or systemctl status dnsmasq . Now you're ready to benefit from your self-hosted DNS server, maximizing performance and letting you use internal domain names to reach local network devices.

How do I point my domain name to an IP address?

This article will show you how you can point your domain name to an ip address..

By pointing your domain name to your IP address, you will allow any potential visitors to view your website. To do this, you’ll need to create an A Record, which will allow you to point your domains and subdomains to a specific IP address.

An A record (or Address record) specifies which IP address is assigned to a particular domain. You can even have multiple A records for the same domain so that you have a backup. In this case, a new record is returned for each query. This is particularly important for large scalable systems.

You will need to set your DNS at your nameserver provider. For more information on how to do this, please view the following article: How do I change the nameservers for my domain name?

Please note: it will take between 24-48 hours for any nameserver changes to become active.

Once this has been done, select one of the headings below to see your next steps:

  • How do I point a subdomain to an IP address?

Start by logging in to your 123 Reg Control Panel .

Next, select Manage All opposite Domains within the ‘All Products and Services’ section.

You will now see a complete list of your purchased domain names. Select the domain you want to update from the provided list.

If you can’t find your domain in this list, you may be able to find it on the Domain Name Overview page within our legacy Control Panel. For more details on this, please read the following article: How do I access and manage my products?

Select Domain

If you’re using our current Control Panel, select DNS in the navbar.

If you’re using our legacy Control Panel, scroll down to the Advanced Domain Settings section and click Manage DNS .

If you’re using our current Control Panel, you will now see a list of DNS records for your domain. From here, click Add New Record .

If you’re using our legacy Control Panel, select the Advanced DNS tab near the top.

Next, create a new record with the following information:

  • Type: select A from the drop-down list
  • Name/Hostname: enter www
  • Value/Destination IPv4 Address: enter the IP address the domain will point to. If you’re using our current Control Panel, you can add multiple values to a single A record.

Once you’ve entered these details, click Save or Add to complete the process.

Please note: it will take between 4-8 hours for any DNS records to become active, provided you didn’t also change the nameservers.

You can also create a Blank Record alongside your original A Record by entering an @ symbol, instead of www. This will mean that people can enter com or www.example.com into their browser and be directed to your IP address of choice.

If, however, this record is to replace an existing one, you can delete the original record by selecting its Delete icon.

How can I point a subdomain to an IP address?

To point your subdomain to an IP address, you will need to do the following:

  • Name/Hostname: enter your subdomain
  • Value/Destination IPv4 Address: enter the IP address the subdomain will point to. If you’re using our current Control Panel, you can add multiple values to a single A record.

Please note : it will take between 24-48 hours for any DNS records to become active, provided you didn’t also change the nameservers.

You can create a Wildcard record alongside your original A Record by entering a * symbol, instead of your chosen subdomain. This will mean that people can enter any.mydomain.com into their browser and be directed to the same place as store.mydomain.com, since they’re pointing to the same IP address.

Setup your Windows hostfile to map domains to IP addresses

Anyone who ever worked on a web application knows waiting for DNS to propagate sucks. You’ve setup an app or site to use a certain domain but have to wait for 24 hours? That’s a lot of wasted time. Or perhaps you want to test something with a fake domain name?

Well, fret no more, because if you edit your host file on Windows, you can easily map domains to IP addresses until DNS does it’s job. In this tutorial we’ll explain how it’s done in a few simple steps.

How it’s done

Important notice: You need Administrator rights on your device to edit your host file. If you don’t have Administrator rights… Well, we can’t help you with that. Sorry!

Open the Command Prompt as an Administrator:

  • Typing “cmd” will reveal “Command Prompt” as an option.
  • Click “Run as administrator”

assign domain name to local ip address

Once the terminal is open, type the following command:

notepad C:\Windows\System32\drivers\etc\hosts

Notepad will open, containing your hostfile.

assign domain name to local ip address

Mapping new domains to IP addresses is very simple. Start a new line, write the IP address, followed with a space and the domain name you want to map to the IP. Like we said, this can be a custom domain. That means it doesn’t really have to exists. For example, if you’re coding an awesome app and want to use gregg.isawesome as a domain name, you can.

Once you are done editing the file, remember to save it. To check if your host file is working, you can try to ping the domain name you just mapped.

This is particularly useful if people have PC-hosted websites (e.g. sites created with Wampserver) on a LAN. Providing the Wampserver “domain” has been created using the technique described in https://www.betterhostreview.com/setup-domain-wamp-server.html and you’ve added the “Allow from all” rule *and* your Wampserver “domain” exists on a static IP address, you can add this “domain” to other PCs on the LAN by modifying the hosts file.

How to point your domain name to a dedicated server's IP address

To point your domain name to your dedicated server's public IP address, you need to create an address record for the domain — an A record. An A record is part of the DNS system and it simply maps a domain name to an IP address.

An A record is stored as a DNS entry on the domain’s name servers. To add an A record for your domain, you can use your domain registrar’s name servers or switch to the name servers provided by Servers.com .

Creating an A record using name servers of a domain name registrar

Before you can add an A record for your domain, you need to find a public IP address of your server in “Dedicated Servers > Manage” section of the Servers.com Portal:

Please use the obtained IP address to add an A record for your domain by following the instructions provided by your domain’s registrar. Here are the links to instructions by several popular domain name registrars:

  • GoDaddy: Add an A record ;
  • Name.com: Adding an A record;
  • Namecheap: How can I set up an A (address) record for my domain?

Please note, that the domain need to be configured to work with the default registrar's name servers.

Creating an A record using name servers of Servers.com

You can change your domain’s name servers to those provided by Servers.com, and then use the “DNS” section of the Servers.com portal to add an A record for your domain.

Changing your domain’s name servers

Before you can manage your domain’s DNS entries using Servers.com Portal, you need to set the following name servers for the domain:

  • ns01.srvrsdns.com
  • ns01.srvrsdns.net
  • ns01.srvrsdns.org
  • ns01.srvrsdns.co.uk

To change name servers of your domain, please follow the instructions provided by your domain’s registrar. Here are the links to instructions by several popular domain name registrars:

  • GoDaddy: Set custom nameservers for domains registered with GoDaddy;
  • Name.com: Changing nameservers for DNS management;
  • Namecheap: How can I change the nameservers for my domain? (see the CustomDNS option).

You may need to wait up to 72 hours for your domain’s new name servers to be propagated.

You can use the following commands to view name servers of a domain to be sure new name servers were propagated.

In Microsoft Windows:

After new name servers are propagated, you can add an A record for your domain in the “DNS” section of the Servers.com portal.

Adding your domain in the “DNS” section of the Servers.com portal

In the “DNS” section of the Servers.com portal click “Add new domain” button. Enter your domain name in the displayed form and click “Save”:

Your domain should now be listed in the “Domains” subsection:

If you are getting error saying “No TXT record with special value, or NS records pointing to our nameservers” , you may need to wait for your domain’s new name servers to be propagated, in some cases this process might take up to 72 hours.

After successfully adding your domain name to the DNS service of Servers.com, you need to point the domain to your dedicated server's public IP address by adding an A record for the domain.

Creating A and CNAME records for your domain

Before you can add an A record for your domain, you need to find a public IP address of your server in “Dedicated Servers > Manage” section of the Portal:

Find your recently added domain in the “DNS” section of the Servers.com portal and click “View details” button, then click “Add A record” . Leave the “Domain” field blank, enter your server’s public IP address in the “IP” field and click “Add record” :

You can also add a CNAME record to make WWW subdomain alias for your domain:

By now you should have A and CNAME records added for your domain as follows:

Your server should be now accessible by your domain name.

Use the following command in Linux to view your domain’s A record:

Or in Microsoft Windows:

Use the following command to make sure your server is running and can be accessed using the domain name:

Reverse DNS Lookup: What is it? How Does it Work? Featured Image

Reverse DNS Lookup: What is it? How Does it Work?

By: hostwinds team  /  february 8, 2024.

What is Reverse DNS?

A reverse DNS (rDNS) is a domain name system that uses IP addresses to find domain names. As the name suggests, it is the opposite of the forward DNS query , which uses a domain name to locate an IP address.

What's the Purpose of Reverse DNS?

Reverse DNS helps verify the identity of a server. It's essentially a security measure used to confirm the legitimacy of a domain attempting to connect to a server. rDNS Lookups are most commonly used by email servers to authenticate message sources and filter spam.

rDNS can also be used for logging and analyzing data. By returning human-readable domain names, one can better understand their sources of incoming connections and identify potential traffic patterns or anomalies.

How Does Reverse DNS Work?

In typical DNS queries, people often trigger the process, usually through a browser. However, with rDNS queries, the initiation typically occurs in the background by servers, network devices, or automated systems.

During a reverse DNS query, the resolver specifically seeks out the PTR (Pointer) record. This record stores the DNS entries that link an IPv4 or IPv6 address to its respective host domain.

The IP addresses are stored in reverse and, depending on the IP version, appended with ".in-addr.arpa" (for IPv4) or ".ip6.arpa" (for IPv6). For example, the PTR record would store a domain with the IP address 104.168.205.10 as 10.205.168.104.in-addr.arpa.

Here are the basic steps of a Reverse DNS Query:

reverse-dns-lookup-thumbnail2.jpg

1. Server Initiates Query

A server, such as a mail server or web server , receives a request to connect from a client (ex. A domain). The server wants to verify the client's identity, so it initiates a Reverse DNS lookup by sending the client's IP address to a DNS resolver.

2. Resolver Checks Cache or Forwards Query

The resolver checks its cache for the domain associated with the IP address. If not found, it forwards the query to the authoritative DNS server. Otherwise, the resolver responds back to the server.

3. PTR Record Lookup

The authoritative DNS locates the PTR record containing the IP address queried IP address. If the record exists, the domain name found in the PTR record is sent to the resolver.

If the PTR record does not exist, the authoritative server responds with an "NXDOMAIN" (Non-Existent Domain) error code.

4. Resolver Responds to Initial Query

If the PTR record exists, the resolver sends the domain name to the server that initiated the query.

If a PTR record does not exist, the resolver will typically forward the error code information to the requesting server.

5. Server Takes Action

The requesting server verifies the domain name's association with the client IP address, typically using Forward Confirmed Reverse DNS (FCrDNS).

Perform Your Own rDNS Lookup

While reverse DNS lookups are typically handled on the backend by the server, there are a few ways you can perform your own reverse DNS lookup:

Windows command shell can be used to perform rDNS lookup using the nslookup command. Here's how that command looks:

Linux command prompt can perform rDNS lookup with the 'dig' command and '-x' flag. That command looks like this:

Online Tools

There are also a number of online tools for reverse DNS lookup. A few of the most notable:

  • Google Public DNS
  • WhatIsMyIP.com
  • Hacker Target

Do You Need Reverse DNS?

Unlike forward DNS, having reverse DNS is not a strict requirement for web hosting.

However, it is highly recommended that domains are capable of rDNS lookup. Doing so allows domains to establish online trust and credibility, while also helping prevent email spoofing and improving email deliverability.

Overall, allowing your domain to accept rDNS lookups (adding PTR record to your IP address) and configuring it to perform its own reverse queries makes the internet a safer place to be.

There is a misunderstanding about hosts file here.

First of all, hosts file have precedence over DNS on most operating systems, you can define them on Linux/Unix operating systems and macOS in /etc/hosts and c:\windows\system32\drivers\etc\hosts on Windows .

So when you add a record in your hosts file like:

and try to open http://repo.sweetsoft/ in your browser, it doesn't send any DNS query to the outside world and uses this entry from your hosts file.

Keep in mind this only works for A record (resolving a name or domain address to an IPv4 address) and AAAA record (resolving a name or domain address to an IPv6 address) and you can not define TXT or MX records for example.

But port numbers are in a different network layer, hosts file only understands names (like repo.sweetsoft) and IP addresses, it's layer 3 and 4 in ISO model (Network/Transport) but port numbers are in layer 7 (application layer).

Check OSI model

enter image description here

OSI vs TCP/IP model

enter image description here

Since hosts file or DNS protocol are not aware of application layers, they have no idea about port numbers too.

Your configuration by adding 127.0.0.1:9000 to your hosts file is like adding port numbers to DNS A records.

After this clarification, you can fix this issue in multiple ways:

  • Running your application on port 80. Fixes your issue and removes any ambiguity.
  • Forward port 80 to port 9000 on your machine via iptables
  • Forward port 80 to port 9000 on your machine via socat:

If you can't change your application port, socat will be the easiest way.

For day to day usage, you can write a systemd service file to run it in the background.

  • 1 Isn't TCP port number in transport layer instead of application layer? –  Billy T Jan 12, 2023 at 19:50

You can go with a different approach:

  • 127.0.1.1 sweetsoft repo.sweetsoft in /etc/hosts
  • Direct repo.sweetsoft:80 and 127.0.0.1:9000 in your HTTP server (AFAIK, Apache can make it using VirtualHost Reference ).

However, it seem to me you are using an app development server. Using Apache to proxy may be an overkill.

Point multiple IP addresses to a single host name

In Windows System, there is this file at C:\WINDOWS\system32\drivers\etc\hosts . This file allows us to default a specific IP address to a host name.

The issue now is whether I can set multiple IP addresses to a host name. For example, can I do something like this:

And expect that the browser can resolve to both of them, see which one will work and thus point at that one?

If not, is there any other way to get the behavior I want?

Note: I am deploying this app in my own local area network, so there is no need for internet.

Normally you would not uses hosts to do this, but your DNS. Most DNS will provide what's called a "Round Robin" if you assign multiple A records to the one name in the zone.

What it would do then, is the first request comes through would receive 192.168.244.128 , the next would receive 192.168.226.129 , so on and so forth. However, by design, your local machine will cache its DNS resolution, and will usually use the same IP address over and over, until it expires (Time To Live, TTL).

Mark Henderson's user avatar

  • 1 EDIT: Nevermind, I stand corrected!! Posted Below –  MagnaVis Feb 13, 2015 at 4:24

Yes, you can do this, I've used it to test round-robin DNS scenarios without having to actually enter the hosts in a DNS.

When an application calls gethostbyname, it gets back the full list of IP addresses (possibly in random order - depending on the libraries / OS).

MarkR's user avatar

  • u mean to say it will pick one randomly..i have a windows server –  Lakshay Dulani Jul 7, 2016 at 11:24

I think you are going about this the wrong way. Let me know if I'm making the wrong assumptions here.

  • You have two windows servers running the same web application, probably on IIS.
  • You want your application to be fault tolerant so that if one of the servers fails, your application is still available.
  • You want this fault tolerance to be transparent to the browser, so that users can continue to access the application with the same hostname i.e. gateway.net

What your trying to do is called round-robin DNS (aka poor mans load balancing) , but your trying to do this from the client side. This does not seem to have the desired effect (at least on my Windows XP box) even if i flush the DNS cache. Windows will only resolve to the first IP in the file. Nonetheless round-robin DNS is not fault tolerant, so this won't help you achieve what you want.

Suggested solution:

Hardware load balancer: Some brand names are Alteon, Big-IP, Barracuda. What this does is basically present a single IP for your users to connect to & it forwards the requests to the web servers. If one of the servers becomes unavailable, then it will no longer forward traffic to it. This is the expensive option.

Network Load Balancing Services: This is a Microsoft technology available on windows server, which will give you a single clustered IP. It achieves the same result as a hardware load balancer, but in a different way. All you need to do is configure it .

  • 1 ZEN-LB is a really simple and easy load balancer. We've had a lot of success with it and love it because its open source (free.) –  Derrick Jan 31, 2013 at 17:49
  • Load-balancer is an alternative and often better, but it is definitely false that Windows returned only the first address. Windows returns multiple addresses since XP at latest, because I was supporting systems that used this in 2004. They are static-order not round-robin, which could be an issue. And some programs USE only the first address returned, but that's not Windows' fault. –  dave_thompson_085 Oct 3, 2020 at 5:00

I have done this on a home network where I assign static IPs to both the wired and wireless network interfaces of a laptop, and from another machine's hosts file point a single hostname to both those ip addresses. It seems to work fine.

From http://www.unc.edu/atn/lsf/docs/7.0.5/lsf_config_ref/index.htm?hosts.5.html~main

IPv4 Example

192.168.1.1 hostA hostB 192.168.2.2 hostA hostC host-C

In this example, hostA has 2 IP addresses and 3 aliases. The alias hostB specifies the first address, and the aliases hostC and host-C specify the second address. LSF uses the official host name, hostA, to identify that both IP addresses belong to the same host.

Peter's user avatar

  • 1 "The format of LSF_CONFDIR/hosts is similar to the format of the /etc/hosts file on UNIX machines." I.e.: the source is not about regular hosts files. –  gertvdijk Jan 27, 2013 at 0:57

My suggestion is to use an internal DNS server with DNS round-robin and TTL=0. If you update the DNS record (also with automatic ip checking system) when an IP/server is down, you can have an high-availability system.

lg.'s user avatar

  • This is not a solution for high availability. DNS is not designed for this and should only be used in conjunction with other fail over methods. A lot of resolvers ignore the TTL cache as well, making this method unreliable. –  Mark Henderson Oct 5, 2009 at 20:41
From http://www.unc.edu/atn/lsf/docs/7.0.5/lsf_config_ref/index.htm?hosts.5.html~main IPv4 Example 192.168.1.1 hostA hostB 192.168.2.2 hostA hostC host-C

Based on this example I did the following 10.18.y.x 192.168.z.x hostA

Where hostA is the hostname of a server I intend to reach from both internal network (192.168.y.x) and VPN (10.8.z.x).

So it works well and I'm able to get samba working through VNP using hostname so it's fine for me to have my connected drives in windows in both case (LAN or VPN connected).

Best regards.

@ Plamen Dimitrov You'll need a device to handle that kind of balance, possibly a switch that can handle BGP in front of your FW- or use your FW if it's capable. If your Ciscos handle BGP look into implementing that. This way you can have both of your ISPs IP going into the Cisco/or switch and the target servers would have valid IPs of 24-bit public IPs (DIFFERENT FROM THE 2 ISP IPs). At that point (you're using 3 different public IP blocks, the one for your servers MUST BE 24 BIT), you'd need to have each of your ISPs know about this solution and they'd have to be willing to support the BGP solution between them, which most will do. Now, when your FQDN resolves, it will resolve to your 24 bit block of IPs, even if 1 ISP lines goes down. The goal is, your 24-bit addresses will always be available due to your ISPs agreeing to route that 24bit address through their lines. This works for VPN too since all you're using for VPN are the 24bit addresses, not either of the IPs from the ISP that you plugged into your cisco/or switch. At that point you have to be wary of BGP FLAPPING where if your lines go up and down a lot, due to a line getting DOS, the DNS addresses will change so much, on the internet, that the DNS servers will AUTOMATICALLY REMOVE THE IPs THAT LEAD TO YOUR 24 BIT BLOCK OF IPs. That's a DOS attack on BGP solutions.

Slight clarification here, at least in the Windows world: You CAN have two IP addresses for a single name in a hosts file. When queried, all addresses are returned. The app (i.e. browser) will attempt to connect to each in turn until a connection is made. IOW, it will try all addresses before timing out. (This is a common misunderstanding as many people believe it will only try the "first" address.)

You can verify this with the following experiment:

Add two or more addresses for a host in the hosts file, one real and the others fake. (Make the fake addresses smaller alphabetically.) Open a browser and try to connect to the hostname. Run netstat -no at the same time. You should see connection attempts to the fake address. (stuck in SYN_SENT) The browser will eventually get to the good address and will connect. There is a delay in connecting, but it WILL work.

  • Not saying you are wrong but I just tried it on my Win 10 Pro using Chrome and it did not work. I tweaked my hosts file (and saved it), then ran ipconfig /flushdns to make sure previous resolutions were forgotten. Tried to open the site (local to my machine) in an incognito window in Chrome to preclude cache results. It just failed (and I waited several minutes to see if it would eventually work). Hit refresh just to be sure. Then I commented out the bogus IP from my hosts file. Without doing anything else I refreshed the page and it worked. Same thing with Firefox. –  Andrew Steitz Mar 15, 2018 at 18:08
  • So, it MAY work based on the application but it definitely does NOT work in two modern browsers. –  Andrew Steitz Mar 15, 2018 at 18:10
  • @AndrewSteitz: it works for me on Windows 10 Home 2004 with Firefox 78.3esr, Chrome 85.something, and IE11 (which identifies as Trident/7.0); the first two take 20 seconds for the bad address before using the good one, and the last only 6 seconds. The same on my older Windows 8.1 also. Edge is now really Chromium so I didn't test separately. Note you can see the (both/all) entries loaded from the hosts file with ipconfig /displaydns although the output format is long and verbose. –  dave_thompson_085 Oct 3, 2020 at 9:22

You can't do this with the hosts file.

You can't do this with DNS either: you can serve multiple IPs for a single name, but the browser will pick just one of those multiple IPs, try it, and if this host is currently down, the browser will display a connection error.

One possible solution is to set up a proxy server and configure these two IPs as the parents for the domain they serve. At least in the case of Squid, the proxy will try one server and, if it fails, try the second server. Then configure your browser to use this proxy server.

  • Not true about round robin: www-archive.mozilla.org/docs/netlib/dns.html Note that the likes of google return multiple DNS records. Despite RFC3484 reordering, it obviously helps to return multiple IPs as a failover strategy. –  BrianEss Oct 7, 2009 at 21:56

Custom domain name setup in router for local access?

Recently I purchased a TP Link router for my home use, and in the instructions they said you can access router cPanel from http://tplinkwifi.net/ domain.

But I am confused on how they have done that? When I pinged the domain from my home, it says it is pinging to 192.168.0.1 but when I did the same from my office, it says ping: cannot resolve tplinkwifi.net: Unknown host .

How they added a custom domain name which works only in the local router environment? Can I do the same?

Also are there any such router models which support local domain setup so that I can setup any domain name and point it to my local IP Address.

I know a way by modifying the hosts file in Windows but that is a lengthy process any way of doing the same via router or any CMS system?

Please advise?

  • What name server is configured on your local/home machine? If it is the router it's as easy as just having him resolve that name locally instead of asking a "internet" DNS server. –  Seth Sep 26, 2016 at 7:40
  • Linksys does the same... essentially, there's a custom route pre-programmed to send any requests to the address to localhost of the router, which is why it only works when you're connected to the LAN of the router. While you could do a port redirect to access this from WAN, it is never advised to do so, as a router's WebUI should never be accessible from WAN, unless its done so via SSH or a VPN tunnel (VPN server on the router, not a 3rd party VPN) –  JW0914 Nov 18, 2019 at 14:11

The router is intercepting and replying the DNS requests by itself.

DNS is the system that resolves a domain name like tplinkwifi.net into an IP address like 192.168.0.1 . The protocol does not have any sort of encryption or security built in - your computer sends a DNS (plain-text) query to the DNS server, receives a (plain-text) response, and trusts it.

When using DHCP, your router can assign you which DNS' to use (a primary and a secondary one), but your computer can still override that.

In my case, my computer is connected to a TP-Link Archer C50 Router ( 192.168.3.253 ) over WiFi, getting its IP ( 192.168.3.200 ) via DHCP but with custom DNS servers set ( 8.8.8.8 and 8.8.4.4 ). The tplinkwifi.net is resolving to 192.168.3.253 (which is not a standard IP for the router to be, so the resolution is not fixed), and even if I perform a DNS query explicitly targeted at the 8.8.8.8 DNS server, I get an immediate response with the local IP:

So the conclusion is that the Router is intercepting the DNS query for that name, and responding it by itself, impersonating 8.8.8.8 . You can see the 1 msec response time (I'm on a really bad internet connection, pinging 8.8.8.8 gives 30ms at best), so it has to be the router forging the response.

You can finally check on Google Public DNS that the actual domain resolves to some other IP. To be able to visit that site, you should either connect to the Internet without going through a TP Link router that resolves this domain, hard-code those IPs on your local hosts file, or use DNS over HTTPs (DoH) to avoid the DNS query being intercepted by the router.

mgarciaisaia's user avatar

Depending on the model and administration interface you may or may not be able to add/modify DNS entries. What is happening is your computer receives the router as its primary DNS server through DHCP. The router either has a DNS server on it or has a hosts file that contains that address.

At no point will you be able to access that address outside of your local network because it is not a publicly registered domain.

If you want full control of DNS on your local network, you can setup bind9 on a raspberry pi and configure the router to point to it.
