How do I find my computer's IP address?

The easiest way to determine your computer's IP address is to visit http://www.WhatIsMyIP.com. The site will display your IP address and other information about your system. If the page does not appear, you may not have a working Internet connection and should try one of the methods below.

Windows 8.x

  • Press Win-r
  • Type cmd and press Enter
  • At the command prompt, enter: ipconfig

The IPv4 address will be a series of numbers following the pattern xxx.xxx.xxx.xxx (e.g., 156.56.27.32).

Windows 7 and earlier

  • Click Start, and then select All Programs
  • Click Accessories, and then Command Prompt
  • At the command prompt, enter: ipconfig

The IP address (or IPv4 address) will be a series of numbers following the pattern xxx.xxx.xxx.xxx (e.g., 156.56.27.32).

Mac OS X

  • From the Apple menu, select System Preferences.... In System Preferences, from the View menu, select Network.
  • In the Network preference window, click a network port (e.g., Ethernet, AirPort, Wi-Fi). If you are connected, you'll see your IP address under "Status:".

Unix-like OS

In many Unix-like operating systems (e.g., Ubuntu, RHEL, OS X, BSD), a shared system administration utility known as ifconfig is available to configure, control, and query TCP/IP network interface parameters from a command-line interface (CLI). Typically, ifconfig can only be used under a superuser account in your terminal.

To obtain your IP Address from ifconfig, enter the following command:

ifconfig

A list of all your network interfaces will appear. Following the heading of the interface whose IP address you're searching for, you will see a "inet addr:" section containing your IP address.

You can usually obtain more information with the command:

man ifconfig
