How to Locate Your IP Address

By Techwalla Internet Editor

Similar to a human fingerprint, an IP address is unique to every computer within a network. An IP address is what gives a computer an identity so that it can exchange data with other computers in the network. Needless to say, it is important that you know how to locate your IP address. Read on to learn how to locate your IP address.

Running Windows

Step 1

Launch the "Start" menu if you're using Windows 2000/XP. Once the "Start" menu appears, select the "Run" command from the list. After you select the "Run" command, a small window with a text box will appear.

Step 2

Type "Cmd" if you're using Windows 2000/XP. After typing the appropriate command word, click on the "OK" button. If you are using Windows 2000/XP, the MS-DOS windows will appear.

Step 3

Type "Ipconfig/all" in the MS-DOS window. Your IP address is the series of series of numbers that will appear next to IP address under the "LAN Adapter" information in the MS-DOS window.

Running Mac

Step 1

Launch the "Apple" menu if you are using a Mac OS X 10.3 and other later Mac versions. Once the "Apple" menu appears, select the "About This Mac" command from the list to launch the "About This Mac" window.

Step 2

Click "More Info" from the "About This Mac" window. Click "Network" from the left pane and choose your network port from the column labeled "Active Services" from the right pane. You can find your IP address at the lower right-hand part of the pane, next to the "Ipv4 Addresses" label.

Tips & Warnings
