SUMMARY STEPS

Detailed steps.

You can connect WAN interfaces either by using straight polarity connectors or reversed polarity connectors.

• Straight Polarity: If Mag-jack RJ45 connector has a dot or digit marked on front housing, it can be used with any type of cables.
• Reversed Polarity: If Mag-jack RJ45 connector has no dots or digit marked on front housing, it can be used with coupler and short cable (Cat5E UTP cable) to connect other devices which doesn’t support auto polarity correction.

To configure Gigabit Ethernet (GE) WAN interfaces, follow these steps, beginning in global configuration mode.

The loopback interface acts as a placeholder for the static IP address and provides default routing information.

To configure a loopback interface, follow these steps, beginning in global configuration mode.

The loopback interface in this sample configuration is used to support Network Address Translation (NAT) on the virtual-template interface. This configuration example shows the loopback interface configured on the gigabit ethernet interface with an IP address of 200.200.100.1/24, which acts as a static IP address. The loopback interface points back to virtual-template1, which has a negotiated IP address.

To verify that you have properly configured the loopback interface, enter the show interface loopback command as shown in the following example.

You can lso verify the loopback interface by using the ping command as shown in the following example.

To configure parameters to control access to the router, perform the following steps.

To manually configure Gigabit Ethernet (GE) LAN interfaces, follow these steps, beginning in global configuration mode.

Static routes provide fixed routing paths through the network. They are manually configured on the router. If the network topology changes, the static route must be updated with a new route. Static routes are private routes unless they are redistributed by a routing protocol.

To configure static routes, perform these steps in global configuration mode.

In the following configuration example, the static route sends out all IP packets with a destination IP address of 192.168.1.0 and a subnet mask of 255.255.255.0 on the Gigabit Ethernet interface to another device with an IP address of 10.10.10.2. Specifically, the packets are sent to the configured PVC.

You do not need to enter the command marked “(default).” This command appears automatically in the configuration file generated when you use the show running-config command.

To verify that you have properly configured static routing, enter the show ip route command and look for static routes signified by the “S.”

You should see verification output similar to the following:

In dynamic routing, the network protocol adjusts the path automatically, based on network traffic or topology. Changes in dynamic routes are shared with other routers in the network.

The Cisco routers can use IP routing protocols, such as Routing Information Protocol (RIP) or Enhanced Interior Gateway Routing Protocol (EIGRP), to learn routes dynamically. You can configure either of these routing protocols on your router.

• “Configuring Routing Information Protocol” section
• “Configuring Enhanced Interior Gateway Routing Protocol” section

Configuring Routing Information Protocol

To configure the RIP routing protocol on the router, follow these steps, beginning in global configuration mode.

The following configuration example shows RIP version 2 enabled in IP network 10.0.0.0 and 192.168.1.0.

To see this configuration, use the show running-config command from privileged EXEC mode.

To verify that you have properly configured RIP, enter the show ip route command and look for RIP routes signified by “R” as shown in this example.

Configuring Enhanced Interior Gateway Routing Protocol

To configure Enhanced Interior Gateway Routing Protocol (EGRP), perform these steps.

This configuration example shows the EIGRP routing protocol enabled in IP networks 192.145.1.0 and 10.10.12.115. The EIGRP autonomous system number is 109.

To see this configuration use the show running-config command, beginning in privileged EXEC mode.

To verify that you have properly configured EIGRP, enter the show ip route command, and look for EIGRP routes indicated by “D “ as shown in the following example:

A push or reset button is available on the rear side of the Cisco 800M Series ISR and it is designed to provide a disaster recovery method for the router.

Push button can be useful for recovery during one of the two scenarios:

• During ROMMON initialization
• For loading a specific configuration file without accessing the router IOS prompt after IOS is up and running.

Table 2-1 shows the high level functionality when the push button is pressed during ROMMON initialization.

Table 2-1 Push Button Functionality During ROMMON Initialization

If you press the push button for more than three seconds and then release the push button after IOS is up and running, IOS detects this event and looks for configuration files in the order of priority.If the IOS finds the configuration file, it copies the configuration file to the startup configuration file. Then the router reloads itself and the new configuration takes effect. If the configuration files cannot be found, pressing reset button has no effect.

The order of priority in which the router looks for configuration file is given as follows:

The Zero Touch Deployment (ZTD) through USB feature in Cisco 800M Series ISRs is an ease-of-use feature that loads a customized configuration from a USB flash drive. This feature requires that the router has no startup configuration in its nonvolatile RAM (NVRAM). The feature also requires that a valid configuration file, with the filename extension .cfg , is stored in the USB flash drive. A valid configuration file can be created by saving the running configuration of a router to flash, USB flash, or to a TFTP Server.

When a router with no startup configuration boots up, it checks for a valid configuration file within the USB flash drive. The pre-requisites for deployment using the Zero Touch Deployment through USB feature are:

• Boot up router with no startup-configuration.
• Cisco USB flash drive inserted in the first available USB slot.
• A valid configuration file in ASCII text with the filename extension .cfg

If the USB flash drive has multiple.cfg files, the router chooses the one with the highest index number in the USB Flash drive. To avoid loading an incorrect.cfg file, ensure that there is only one.cfg file in the USB flash drive.

The Cisco 800M Series ISR uses second core and it is actively used in detecting USB flash drive if 3G Wireless WAN module is present on the router. If 3G Wireless WAN module is not present, USB flash drive is detected by the IOS. When 3G Wireless WAN module is present, USB detection is a bit delayed for the Cisco 800M series ISR due to the delay in second core initialization. While system startup is in progress and push button is pressed, a timer is started to check the completion of second core initialization. For some reason if second core takes more time, system reports an error message and continues the normal start up. After second core initialization router waits up to 10 seconds for USB detection and then complete the configuration. In case the USB flash drive does not contain a deployment configuration, router enters the configuration mode.

IP Addresses

Every computer that connects to the Internet has to have an IP address assigned to it. IP addresses identify where the computer is located on the Internet so that Web servers and mail servers can send data to the correct computer. An IP address is a series of four numbers separated by dots:

66.117.136.6

208.25.127.254

192.168.1.1

PUBLIC AND PRIVATE IP ADDRESSES

There are two types of IP addresses – public and private. Public IPs are used by routers and by computers connected directly to DSL modems without a router. Private IP addresses are special IP addresses that are known only to a router and its home network. A Web server will not deliver Internet data to a private IP address. It will deliver the data to the router (which has a public IP address) and then the router will deliver the data to the computer that has the private IP address.

Routers are special because they have two IP addresses. An IP address is assigned to each of the router’s two “interfaces”. The first router interface is called the WAN (Wide Area Network) interface. This is the side of the router that faces the Internet and has a public IP address. The second router interface is called the LAN (Local Area Network) interface. This is the side of the router that faces the home network’s computers and has a private IP address.

IPv4 addresses are usually assigned using the DHCP protocol. How this happens, depends on the particular DHCP server running on the router...

With DHCP, addresses are leased for a certain time period, so if a device reboots requests an address before the old lease expires, the router usually gives the same old address (based on DHCP client ID, or on the MAC address).

Some DHCP servers remember which address was issued even for a while after the lease expires, so they always give the same address to the same device.

If the device wasn't seen previously, it depends on the implementation – usually the new address is chosen randomly, but sometimes sequentially, and sometimes based on some sort of a hash on the MAC address so that the router at least tries to give the old address again.

For example, to quote the manual page dhcpd.conf(5) of the ISC DHCP server dhcpd :

For IPv6, there is a similar protocol DHCPv6, to which the answer above still applies.

However, many networks use a simpler "stateless autoconfiguration" protocol in which the router only broadcasts the prefix (aka network address), and devices assign their own IP addresses. The assignment is done in two ways:

With normal "Stateless Autoconfiguration" ( RFC 4862 ), the 'host' part of IP addresses is based on the device's hardware address . For 48-bit MAC addresses, the second bit is flipped, and ff:fe is inserted in the middle (to pad to 64 bits)

For example, prefix 2001:470:1f0b:915::/64 plus MAC address 48:5d:60:e8:65:8f results in IP address 2001:470:1f0b:915: 4a5d:60 ff:fe e8:658f .

With "Privacy Extensions" ( RFC 4941 ), the 'host' part is chosen randomly – and a new address is added every 10 hours, too.

Note that "Privacy Extensions" are almost always used in addition to the normal "stateless" MAC-based IP address.

• You mention IPv4, is this any difference with IPv6? –  agz Mar 31, 2013 at 18:10
• @agovizer: Yes – I updated the answer. –  u1686_grawity Mar 31, 2013 at 18:29
• If it's simply a hash, wouldn't a single IP address be applied to more than one host? –  Pacerier Sep 9, 2013 at 16:13
• @Pacerier: Depends on how well-designed the hash is, how many IP addresses you get to choose from, etc. Also note that I said "tries". If the resulting IP address is already in use, the router might just assign another one. –  u1686_grawity Sep 9, 2013 at 19:21
• In case of Ad hoc network, How IP addresses gets assigned ? As there is no central server. –  pathe.kiran Jul 13, 2017 at 17:52

I think it is important to point out that routers do not assign IP addresses : routeurs receive an IP packet on an interface and send it almost unchanged on another interface (the changes I can think of is decreasing the TTL and updating the checksum of the IP packet; even changing the IP address in the packet (NAT) is beyond the task of a router).

The devices that are called home routers are much more than routers, they also include some of the following functionalitys/services:

• DHCP Server (this is the service that assigns IP addresses),
• ADSL Modem (to negotiate a connection to the ISP),
• Firewall (to filter incoming and outgoing connections),
• Inbound and outbound NAT device (to share the single IPv4 address allocated by the ISP for all the devices on the home network),
• WiFi Antenna,
• Web Server,
• Console (web, ssh or telnet) to configure the device,

(Note: firewalls can usually do Inbound and outbound NAT and routing, even though those 4 functions can be done using dedicated devices.)

In large Enterprise deployment, the DHCP Server is often hosted on dedicated Linux or Windows servers (usually a cluster) that does not have anything to do with routers.

Generally (for IPV4), the system used is called "DHCP", and works, broadly, as follows.

• The router runs a "DHCP Server", which has a table with IP's which can be used.
• Each computer makes a DHCP request, which is basically a packet (with its MAC address) sent on the network saying "What IP can I have ?"
• The router looks at the packet received and says here is your IP address, gateway, DNS server [and anything else]
• The computer then configures itself.

The MAC address can be used by the DHCP server table to make sure the machine gets the same IP address, if available each time.

• Sorry for the necropost. Is the IP assigned by the router the internal one? I assume if there is a nat server, it will provide an external one? –  MSIS Sep 5, 2022 at 22:17
• @MSIS The DHCP server will provide an IP address from whatever range it is programed to. In the case of NAT the IP address should be an Internal one. DHCP does not know anything about NAT - it just assigns the IP, DNS server, gateway etc. The router would need to identify the IP needs to be natted. –  davidgo Sep 6, 2022 at 2:05

How to assign an IP address to a device

First off, let's start with the basics. An IP address is a unique identifier assigned to every device that connects to a network. This allows devices to communicate with each other and access the internet. Without an IP address, your device is essentially invisible on the network.

So, how do you assign an IP address to a device? Here are the steps:

Step 1: Determine the network address

The first step is to determine the network address of the router or switch to which the device will connect. This is usually a series of four numbers separated by dots, such as 192.168.0.1 or 10.0.0.1. You can usually find this information in the router's network settings or switch.

Step 2: Determine the subnet mask

A subnet mask is a number that determines the size of the network that the device will connect to. It is usually given as a series of four numbers separated by dots, such as 255.255.255.0. This number is used to divide the IP address into two parts: the network address and the host address.

Step 3: Determine the range of available IP addresses

The router or switch is configured to assign IP addresses to devices on the network from a range of available addresses. This range is usually determined by the subnet mask. For example, if the subnet mask is 255.255.255.0, then the range of available IP addresses is from 192.168.0.1 to 192.168.0.254.

Step 4: Assign a static IP address

If you want to assign a specific IP address to the device, you can assign a static IP address. This is useful if you have a device that needs to always have the same IP address. To do this, you will need to enter the IP address, subnet mask, and default gateway into the device's network settings.

Step 5: Enable DHCP

Alternatively, you can set the device to use Dynamic Host Configuration Protocol (DHCP) to automatically obtain an IP address from the router or switch. This is the default setting for most devices and is often the simplest option. DHCP allows the router or switches to assign an available IP address to the device when it connects to the network.

Step 6: Test the connection

Once you have assigned an IP address to the device, test the connection by attempting to connect to the internet or other devices on the network. If everything is working properly, your device should be connected and ready to go!

Assigning an IP address to a device is essential in getting it connected to a network. Whether you choose to assign a static IP address or use DHCP, the process is relatively simple once you understand the basics. If you're still having trouble connecting your device, don't hesitate to seek assistance from a knowledgeable IT professional.

How to Configure IP Addresses on a Cisco Router

Configuring routers is a routine operation for network administrators. Enterprise-grade routers are very different from consumer-grade routers, though. Consumer-grade routers come mostly configured out of the box. Likewise, consumer-grade ISP services typically configure home ‘routers’ with a dynamic IP address. 

In contrast, business-grade ISP services assign static IP addresses. Before an enterprise-grade router can be installed in a network, it needs to have an IP address assigned to it first. So, we will walk through how to configure an IP address on a Cisco router today.

Configuring a Cisco router with an IP address is not a complicated process. There are typically four steps involved:

Verify the current interface configuration of the router

Choose the interface that you want to assign an IP address to

Assign the IP address

Enable the interface on the Cisco router

We will walk through each of those steps, explain how to complete them, and why they are essential. 

An Overview of How to Configure IP Addresses on Cisco Devices [VIDEO]

In this video, Jeremy Cioara covers assigning IP addresses and enabling interfaces on Cisco routers. Unlike switches, which are essentially plug and play, routers require a bit of configuration before they can do what they were designed to. You'll see a straightforward, four-step process to enabling interfaces that will equip you to do this yourself.

How to Display Interfaces on a Cisco Device

Before you assign an IP address to a Cisco router, you need to know the current configuration of that device. Typically, Cisco routers have all their interfaces shut down out of the box. Therefore, we need to verify the state of those interfaces before proceeding, especially if this router is being re-used. 

The rest of the instructions through this article will assume that you are connected to the Cisco router. 

To show the interfaces in a Cisco router, use the ‘show IP interface brief’ command in the console window. For example, this command will output the following information:

Each interface and interface name

The IP address for that interface

Whether each interface is up or down on the Layer 1 level (status column)

Whether each interface is up or down on the Layer 2 level (protocol column)

The Status and Protocol columns will have one of three messages:

Administratively Down

Each message has a clear indication of the status of its associated interface. The ‘Up’ message is self-explanatory. That means that the associated interface is working correctly. The ‘Administratively Down’ message indicates that the interface is disabled by configuration. Otherwise, the network admin purposefully disabled that interface for some reason. Finally, the ‘Down’ message means the associated interface isn’t working for other reasons (like unplugging the network cable from the network port). 

Out of the box, Cisco routers have the ‘Administratively Down’ configuration for each interface. This is different from Cisco Switches. Cisco Switches come pre-configured out of the box. They can be safe to implement into an existing network almost right away. On the other hand, an unconfigured router can make a network inoperable. 

That’s because an improperly configured router can send data from the network into a black hole. Routers are the pieces of equipment that push data to and from networks or network segments. If a router isn’t correctly configured, it won’t know where to send that information to. Hence, that data is sent to purgatory. It is simply dropped from the network. 

So, you need to verify the status of the interfaces on a Cisco router before you configure an IP address for it. We need to configure as much of the router as possible before connecting it to a network, so this is an excellent first step. 

What is the Difference Between Status and Protocol on a Cisco Router?

When you use the ‘show IP interface brief’ command in the console when connected to a Cisco router, the router will dump information about each interface on the router to the console display. That information will include the link-state labeled as ‘Status’ and ‘Protocol.’

Many new network admins may not understand the difference between both states. After all, aren’t they both the same?

The ‘Status’ and ‘Protocol’ states represent different layers of the OSI networking model , though. The ‘Status’ column represents Layer one, or the physical connection layer. The ‘Protocol’ column represents Layer 2 of the OSI model. The physical layer explains whether a cable is physically connected or if the physical hardware for that interface is working correctly. The protocol layer explains whether that interface is receiving signals that it can understand and recognize. 

Understanding the difference between Layer 1 and Layer 2 and their operational status is essential for configuring Cisco routers and diagnosing issues with them down the road. 

How to Choose an Interface to Assign an IP Address on a Cisco Device

When we configure an IP address for a new Cisco router, we need to verify the current state of the interfaces of that router. After we confirm the state of those interfaces, we need to select an interface in the console before configuring an IP address. This process is easy. 

Running the ‘show IP interface brief’ command in the console of a Cisco router will list each interface and the designation for those interfaces. Pay attention to those interfaces. Also, make sure to match the interface in the console with the physical interface on the Cisco router. That way, you don’t plug the ethernet cable into the wrong port. 

To select an interface in the console, first enter the global configuration mode in the router. Then, use the ‘configure terminal’ command in the console to enter configuration mode. 

After switching to the configuration mode in the router, use the ‘interface’ command followed by the interface itself to select that interface. You can also add a question mark after the ‘interface’ command instead of the interface designation for additional help. 

Interface g0/0

In the example above, we used interface g0/0. That means we selected the first interface that is a gigabit ethernet port on our router. The interfaces in your Cisco router may be labeled differently depending on the device you are configuring. 

How to Assign an IP Address to a Cisco Router

Before we can assign an IP address to a Cisco router, we need to complete a couple of steps. First, we need to run the ‘show IP interface brief’ command. This will list each interface in the router as well as their status. Then, we need to enter global configuration mode with the ‘configure terminal’ command and select an interface using the ‘interface’ command in the console of that router. The ‘interface’ command must be followed by the interface designation. Once we have our interface selected, we can assign an IP address to it. 

Assigning an IP address to an interface in a Cisco router is as simple as using the ‘IP address’ command. That command must be followed by the IP address for that interface port as well as its subnet.

Ip address 192.168.1.1 255.255.255.0

Entering that command will not produce any confirmation messages unless there was an error. In this case, no news is good news. 

After assigning the IP address to an interface in a Cisco router, run the ‘show IP interface brief’ command again. When that command displays information about each interface in the router, you should see the IP address assigned to your chosen interface under the IP address column. If you do not, try repeating the process. 

That’s it! It’s that simple to assign an IP address to a Cisco router.

How to Find the IP Address to Assign to a Cisco Router

Many new network admins may not understand where to find the IP address to assign to a new Cisco router. Those admins may have received that information from a senior network administrator or through documentation, but if those resources aren’t available, where would you find the IP address to assign to a Cisco router?

Often, that information comes from the ISP (Internet Service Provider). Businesses will typically choose to have a static IP address assigned to them from their ISP. 

This is done for stability reasons. In a dynamic environment, the external IP address of a network can be changed by the ISP. If your business hosts something like a VPN , though, that could be an issue. Static IP addresses keep network configurations static for things like VPNs or DNS entries. 

This is in stark contrast to the typical consumer-grade ISP connection. In these cases, the ISP will always use DHCP to assign a network address to consumer customers. But, of course, a business can use DHCP addresses, too. This is more common with small and medium-sized companies that may not need to host services that depend on a static IP address. 

Cisco routers can be configured to use DHCP instead of being assigned a static IP address, too. To do that, add ‘dhcp’ instead of the IP address and subnet mask to the ‘IP address’ command in the console in a Cisco router.

Ip address DHCP

How to Enable an Interface on a Cisco Router

After configuring an IP address for a Cisco router, you will most likely need to enable the interface to be active. Cisco routers come with all the interfaces on them shut down out of the box. This is for important network safety reasons. So, the interface you just configured needs to be enabled. 

First, we can verify a Cisco router’s status and configuration using the ‘show run’ command from the configuration console for a Cisco device. That command will display all the current information for that device and its interfaces. More than likely, the information displayed from that command will be too much to fit on your screen. Use the space button to jump through the configuration information.

Look for the configuration information for the interface you need to enable. This should show that the interface is currently administratively down. 

Once the status of that interface has been verified, we need to enable it. First, we need to select that interface. Use the ‘interface’ command in the console followed by the interface name.

E.g., interface GigabitEthernet0/0

In our example, the name of the interface we are working with is GigabitEthernet0/0. Of course, the name of the interface you are working with may be different.

Now that the interface is selected, use the ‘no shutdown’ command to enable that interface. If all goes well, you should see three messages. The first message shows that the interface is down. The next two messages should state that the ‘Status’ and ‘Protocol’ are now up. You should also see lights blinking next to the physical interface port that you just configured on the router. 

Remember that the status and protocol states in a Cisco router represent different layers of the OSI network model. The status state represents layer 1, while the protocol state represents layer 2. This is why the console shows two different status prompts after running the ‘no shutdown’ command. 

Wrapping Up

We covered a lot of information in this article! Consider this guide a rough tutorial on assigning an IP address to a Cisco router. Still, we did not cover other important topics like what a subnet is or how to secure a router. If you would like to learn more, consider our CCNA training . 

Though assigning an IP address to a Cisco router is easy, it is also very routine. Furthermore, this is a function that you will perform a lot as a network admin. So, let’s go over how to assign an IP address to a Cisco router with a short and sweet tl;dr instruction set.

Verify the interface status with the ‘show IP interface brief’ command.

After verifying all interfaces are down, enter global configuration mode with the ‘configure terminal’ command.’

Select the interface you want to configure with the ‘interface’ command followed by the interface name.

Assign an IP address to that interface with the ‘ip address’ command followed by the IP address and the subnet mask for that interface.

Run the ‘show IP interface brief’ command again to verify the IP address has been assigned to the network interface. 

Run the ‘no shutdown’ command to enable that interface. 

That’s it! Keep these instructions handy until they become second nature. Businesses use static IP addresses for all sorts of things, but above all else, they use static IP addresses to keep networks from breaking or requiring additional maintenance. Understanding how to assign an IP address to a Cisco router is vital for any network admin.

How to Set a Static IP Address

There are many reasons that you may need to change and set a static IP address for your IP device, such as a managed switch , wireless router , or outdoor access point . One reason is because an installation scenario doesn’t have an active network with DHCP services. Some other reasons you may need to set a static IP are because you use a dedicated web server, host server, VPN, or VoIP services.

Setting static IP addresses can help to avoid network conflicts which could cause certain devices to stop working correctly. However, in most installation scenarios, users will use a regular network and will not need to use a static IP. Setting a static IP address is an advanced networking function, and a basic, fundamental knowledge of TCP/IP is needed.

In general, statically address devices outside of your DHCP pool range, which in most home networks is your router . For reference, the DHCP pool range for TRENDnet products is usually (but not always) 192.168.10.101 to 199.

1. Access the Control Panel

In the Windows search bar, type in “ncpa.cpl” and then press enter.

If you are not using Windows 10, follow the steps below instead.

• On your keyboard, press the “Windows” and “R” keys at the same time.
• Enter “ncpa.cpl” in the window that pops up.

Note: Network connections will display the network adapters that are currently connected to your computer.

2. Select the Network Adapter

Right click on the network adapter that is currently connected to the device that you are trying to configure. Usually, it will be the adapter with the word “Ethernet” in the name.

3. Select Properties

Select “Properties” from the drop-down menu.

4. Select Internet Protocol Version 4 (TCP/IPv4)

Double-click on “Internet Protocol Version 4 (TCP/IPv4)”.

5. Manually enter IP address and subnet mask

Select “Use the following IP Address” and then input the following information in the corresponding fields:

IP address: Check the device that you are connected to in order to locate the IP address. The first three sets of digits should match. For this tutorial, we will use IP address 192.168.10.10.

Subnet mask: The subnet mask between the device that you are trying to connect to needs to be the same as your PC. For this tutorial, we will use subnet mask 255.255.255.0

6. Save Settings

Click the OK button on “Internet Protocol Version 4 (TCP/IPv4) Properties” window, and also click the OK button on “Ethernet Properties” window.

Note: The OK buttons must be clicked in both instances or your settings will not be saved.

7. Revert Back to DHCP

To set your computer back to DHCP, repeat steps 1-4 again. When you get to the “Internet Protocol Version 4 (TCP/IPv4) Properties” window, click “Obtain an IP address automatically”. This will allow your PC to be assigned a random IP address on your network.

Operating System The operating system (often shortened to OS) is the software your computer or mobile device uses to perform basic functions. Microsoft Windows, Apple macOS, and Linux are the most popular operating systems for computers and laptops, with Android and iOS for mobile devices.

Browser A browser (short for web browser) is a software application that allows you to access the internet. Some of the most popular browsers are Chrome, Safari, Edge, Internet Explorer, and Firefox.

Network Adapter A network adapter allows a device to communicate and connect to a local area network (LAN), the internet, or other computers. Network adapters can be wired or wireless , and they can be visible or hidden from plain sight.

IP Address An IP address is a unique identifier for devices that access the internet or devices on a local area network. It uses a string of numbers and/or letters with periods or colons. To identify your IP address, type “what is my ip” into a search engine, like Google or Bing. You can also visit whatismyipaddress.com or whatismyip.com .

Dynamic IP address A dynamic IP address is an IP address that can change over time. Your IP address may change each time you connect. Most IP address assigned by your ISP will be dynamic IP addresses.

Static IP address A static IP address (also referred to as a manual IP address or static IP configuration) is an IP address that remains unchanged over time. Your IP address remains the same (or static) each time you connect (from the same location). Your IP address may change if you connect to a different network in a different location.
