It's not visible for local computer, you need to take help of some remote computer which can get the IP of connected socket.

Following samples take advantage that technique,

thats what is explained in the articles on those links. As I said earlier the technique is to use some remote interface (web interface etc.) to get you your external IP. The remote computers can read your external ip using getpeername on the socket which is connected bet. you and remote computer.
