How to Find Your Computer IP Address in Windows

An Internet Protocol address identifies your computer on a network. Home computers typically connect to the Internet via a router and cable or DSL connection. In this type of setup your computer's IP address only identifies it on the local network. This includes the router and any other computers you have connected at home. The router has its own IP address to identify itself on the Internet. When you use a service such as WhatIsMyIP.com, the IP address returned is your router's address. Determine your computer's IP address using the tools included with Windows.

Tips & Warnings

• If performing the IPCONFIG command gives you the following error: "'ipconfig is not recognized as an internal or external command" you may need to approach a slightly different method: - From the C: drive in DOS, type CD\WINDOWS\SYSTEM32 - Try the IPCONFIG command from this location again
