How do I determine my computer's IP address?

On this page:


Windows

Windows 7, Vista, XP, and 2000, using the command prompt

  1. Click Start, and then select All Programs (Windows 7, Vista, and XP) or Programs (2000).

    Note: If this doesn't match what you see, refer to About navigation settings in Windows.

  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 (i.e., 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 system tray, 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... . Look for the address next to "IPv4 IP Address".

Mac OS X

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

OS X 10.5

  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, modem). If you are connected, you'll see its IP address under "Status:".

OS X 10.4 or 10.3

Via the web

If you are connected to the Internet, visit ShowIPAddress.com. The site will display your IP address and other information about your system. If the page does not display, you may not have a working Internet connection and should try one of the above methods.

In IU housing, offices, or labs

In Indiana University housing, UITS uses DHCP to assign a different (i.e., dynamic) IP address to your computer each time you turn it on. If you have a problem connecting to Internet resources, or otherwise suspect a problem with DHCP or DNS, contact your campus Support Center.

If your workstation is in a university office or lab, your computer should have an IP address that never changes (i.e., a static IP address). Usually, your local support provider (LSP) registers your computer and assigns the IP address. If this has not happened, email:

IUB: dns-admin@indiana.edu IUPUI: dns-admin@iupui.edu

Include your computer's hostname, which can include letters, numbers, and hyphens (-); no other characters are allowed. See In Windows, how do I find my computer's hostname? For recommended IU naming conventions, see At IU, what naming conventions does UITS recommend for Windows computers and groups?

Also include:

  • The primary user or administrative contact; include the full name, and IU username or email address (if it's your workstation, you are the primary user)
  • Your department
  • Your computer's manufacturer and model, and the operating system installed (e.g., Windows XP)
  • The building and room number where your computer is located

If UITS receives your request before 3pm on a business day, your computer should be in the name server the following morning. If requests arrive after 3pm, UITS will process them the following business day.
