Strange problem

[Stranger]

I am going through some strange problem. I have internet connection (wireless) and i have taken connection in XXXX but my ip address shows my Ip YYYY and sometime ZZZZ.
I am confused by seeing this problem.
Why my ip showing yyyy when i am using it in xxxx and connection is from address of xxxx

Thanks indranil and raymond to solve my problem

It's seems to be their gateway server IP. Due to NAT translation it may happen . You don't need to worry about that matter.

IP addresses are not really 100% accurate in determining your location.
