How to Find Someone's IP on Yahoo Messenger

By Darla Ferrara

Windows operating systems offer a way for computer users to obtain IP addresses for every device encountering them via the Internet, such as Yahoo Messenger (YM). The IP address is simply a series of numbers, and will not tell you how to contact a person. Still, if you are curious about the IP on the other side of the Yahoo! Messenger screen, that information is readily available through your operating system.

Step 1

Press the "Start" button at the bottom of your desktop. In Windows XP, click on "Run" from the Start menu, in Vista or Windows 7; navigate to the "Search" text box in the Start menu.

Step 2

Type "CMD" in either in the Run dialog box or in the Search text box, then press the "Enter" key on the keyboard, this will open a Command screen. Press the "-" icon in the upper right corner of the Command screen to minimize the program.

Step 3

Open Yahoo! Messenger by clicking on the icon on your desktop or accessing it from the Start menu.

Step 4

Log in to your account on Yahoo! Messenger. In order for the process to work, you must initiate an Instant Message with the individual and send them a file, such as a photo. Other options include Cam-to-Cam viewing or the "Share Picture" function on YM.

Step 5

Click on the tab for the Command screen to expand the application. Navigate to the Command prompt (C:\).

Step 6

Enter "netstat -a" at the Command prompt and press the "Enter" key on the keyboard. This command provides a listing of all addresses and ports on your computer. Local Address is your computer and the port number in use. Foreign address is the remote host information.

Step 7

Select the IP for the Yahoo! Messenger file transfer. If you sent a file, that is peer to peer, so look for Port 80 or Port 81 under Local Address. If you used a Cam-to-Cam viewing, look for Port 5100. The number under "Foreign Address" is the IP of the individual receiving the file.

Tips & Warnings

  • This process works on other messenger programs as well, such as AIM.
  • Port number assignments vary based on the configuration of software.
