HOW TO: Find the Internet Protocol (IP) information for your windows computer.

There are time when you need to find out the Internet Protocol (IP) information for your computer.

A simple way to get just your IP address is to use our What-is-my-IP-address page.

Windows has a command line utility to show you more information. The program is named IPCONFIG or WINIPCFG, which one your system has depends on the version of windows that you are using. Newer systems tend to have IPCONFIG.

To get the IP information for your computer, open a command prompt. If you are not sure how to do that, see How to open a Command Prompt.

At the command screen type "ipconfig /all" (without the quotes, and with a space between ipconfig and /all), then press enter. If it doesn't understand that , try "winipcfg /all" (without the quotes and with a space between winipcfg and /all).

It should display a lot of information. Look for the portion of the display that gives information about the Ethernet (if you connect to the internet by a network) or for the modem (if you connect to the Internet by a modem).

Some of the common things you would be looking for are:
IP address (a number like 200.30.140.123).
Mask, (a number like 255.255.255.0). 
Nameservers, (a number like 200.30.140.123).


If you connect to the internet by a modem, DSL, or Cable; you will probably have to be connected for the information to be valid. You may be assigned a new number every time that you connect, or every time the provider has to reset their equipment. In the case of dialup, this will probably be every time you dial in. In the case of cable or DSL, this will probably stay the same number for long periods of time, but it may change occasionally.
