How do I determine my computer's IP address?

On this page:

Note: For help navigating, see Getting around in Windows.


Via the web

If you are connected to the Internet, visit 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.

Note: This IP address is known as your external IP address; it may differ from those mentioned in different sections of this document.

Windows

Windows 8.x

  1. Press Win-r .

  2. Type cmd and press Enter .

  3. 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, Vista, and XP, using the command prompt

Important: As of April 8, 2014, Microsoft no longer supports Windows XP with security updates. To ensure the highest security standards, the UITS Support Center no longer registers Windows XP devices to the IU network. UITS strongly recommends that you look into the options for replacing or upgrading your Windows XP computers for full compatibility with IU systems. See About end of life for Windows XP.

  1. Click Start, and then select All Programs.

  2. Click Accessories, and then Command Prompt.

  3. At the command prompt, enter: ipconfig

    The IP address (or IPv4 address, if you are using Windows 7 or Vista) will be a series of numbers following the pattern xxx.xxx.xxx.xxx (e.g., 156.56.27.32).

Note: If you are using PPP with a modem at home, your IP address will change each time you log in.

Windows 7, without using the command prompt

  1. In the notification area, click the network connection icon and select Open Network and Sharing Center.

  2. To view the IP address of a wired connection, click Local Area Connection.

    To view the IP address of a wireless adapter, click Wireless Network Connection (Network Name).

  3. Click Details... . Your IP address will appear next to "IPv4 Address".

Windows Vista, without using the command prompt

  1. From the Start menu, right-click Network, and then select Properties. This opens the Network and Sharing Center.

  2. To view the IP address of a wired connection, click View Status to the right of Local Area Connection.

    To view the IP address of a wireless adapter, click View Status to the right of Wireless Network Connection.

  3. Click Details... . Your IP address will appear next to "IPv4 IP Address".

Windows XP, without using the command prompt

Important: As of April 8, 2014, Microsoft no longer supports Windows XP with security updates. To ensure the highest security standards, the UITS Support Center no longer registers Windows XP devices to the IU network. UITS strongly recommends that you look into the options for replacing or upgrading your Windows XP computers for full compatibility with IU systems. See About end of life for Windows XP.

  1. From the Start menu, right-click My Network Places, and then click Properties.

Mac OS X

To find the IP address of a Mac OS X computer:

  1. From the Apple menu, select System Preferences... . In System Preferences, from the View menu, select Network.

  2. 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
