How do I get ip address while I am chatting gtalk?and also I need to exact location where he/she is chatting?

Can anyone solve this problem?

First, please pay more attention to posting guidelines. This was moved from the Introductions forum which is clearly marked as NOT for questions.

Second, getting their IP will NOT give you the exact location. All it will tell you is the ISP that issued the IP. While this may indicate a general location it also may not.
