How to Find Someone's IP on Yahoo Messenger
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.
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.
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.
Open Yahoo! Messenger by clicking on the icon on your desktop or accessing it from the Start menu.
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.
Click on the tab for the Command screen to expand the application. Navigate to the Command prompt (C:\).
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.
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.
