How to Find Your Own IP Address

Windows 2000, XP, or Vista (source)

By default, Windows Vista is not set to show the Run command from the Start menu. You can change this in Vista Preferences or use Search to find the Run command.

To use the Search command in Windows Vista type:

1. From the Start menu click Search
2. Type Run
3. Double-click the Run shortcut

Once you have the Run command window start with step 2 below

1. From the Start menu select Run
2. Type cmd in the Run window field
3. Type ipconfig /all

Unix

• In a terminal window, use the command

  ifconfig -a

  or, if this is not found use,

  /usr/sbin/ifconfig -a

  You may get a variety of responses. The one you want is one that includes the words "BROADCAST" and "inet," where "inet" introduces the IP address -- e.g.,

  le0: flags=<863up,broadcast,notrailers,running,multicast> mtu 1500 inet 128.8.10.95 netmask ffffff00 broadcast 128.8.10.255

• In case the ifconfig is not installed: nslookup
  

nslookup machine-name.domain.name
