Im confused, according to your location, your in India!!! So why do you act surprised when the WHO IS search led to India? Or is this friend of yours located somewhere else?

Yes you can trace his IP address, but its only usefull for finding his ISP and reporting an abuse. Thats a common way for people to knock out spammers and email abusers. My first advice to you is to not only use WHO IS searches, but also do a tracert in the command prompt on the IP address you found in the header. One of the last 2 hops will show his ISP. The reason why you wanna do a tracert and WHO IS search is because a WHO IS search sometimes will bring up a company that is basically the ISP of the ISP of your friend, or in this case the ISP of the ISP of the internet cafe, if you know what I mean.
