You may notice that the title of this post too SE oriented. We use Trace IP, Find IP, Knowing IP and Grab IP Address. All those synonym have same meaning: How we know the Internet Protocol Address of a buddy or user friends via Instant Message of Yahoo Messenger. If we get their IP address, that mean we can know where he came from. Of course we can not make sure whether the IP address is their real Address or just a Proxy. But, at least we know their IP used to connect in Yahoo Messenger.
They are two step how to trace or find IP address of a friend in IM of YM: Manually and Automatically. IF you want to use software or automatic software to grab IP or knowing IP just try to use Sharp IP Getter. If you want to use manual ways, follow my instructions below:
First open your command prompt windows through Start menu then All Program then Accessories then Command Prompt. Or you can just open it via Run cmd Command.
After that Login to Yahoo Messenger and make an Instant Message with one of your friends. and this it the IMPORTANT thing that you must do: Send them a File! or Make Cam to Cam or Share Picture. This will make you and your friend connected via Peer to Peer. Peer to Peer allow us to know or see each others IP. The next question? How we know their IP that use Peer to Peer. That why we open Command Prompt and with a little task we can find their IP.
Type in the Command prompt a code command neststat -n or netstat -a (note: between netstat and -n or -a is spacing character) . If you want more detail about the info type netstat -anvb command. This will show all the connection that came to us. Then all you need to do just find the correct IP. Usually the IP for Peer to Peer use remote port 80 or 81 (File Transfer), Port 5100 (Webcam), Remote Port 5000 or 5001 (Voice Chat). Note: Remote Port might change time to time.
