Use the 'ifconfig' command. The normal 'ifconfig' command will throw out a lot of unnecessary data and cause a bit of confusion for the user. The following command line will show your internal IP address, and remove most of the unnecessary information:

ifconfig | grep "inet" | grep -v 127.0.0.1

This command will remove entry 127.0.0.1, the data will always appear no matter what kind of computer you use. This is a type of repeated response that you can ignore if you are only interested in the IP address.

Go to your router (router) configuration page. Almost the entire router can be accessed through the web interface, where users can view and adjust settings. Open the web interface by typing the router's IP address into a web browser. Look through your router's reference to find the specific router address. The most common router addresses are:

192.168.1.1

192.168.0.1

192.168.2.1

Open Router Status. The location of the external IP address for each router is different. Most of them show up in Router Status or WAN (Wide Area Network) Status.

Under Internet Port in Router Status, your IP address will be displayed in full. It consists of 4 sequences of characters, each with a maximum of 3 characters.

This is the IP address of the router you use. Any connection made from this router carries that IP address.

This IP address is assigned to you by your carrier. Most public IP addresses are 'dynamic', meaning it changes over time. This address can be hidden using a proxy server.
