Upgrading to 1Gb Yahoo China Account
1. Sign-in to Yahoo Messenger, add a contact, sign-out
2. Go back to cn.mail.yahoo.com (all pages would be in Chinese)
3. Click the 1G orange label (graphic) *look at the lower right of the page*

b) knowing the ip-address u can know the websites name.
Thats called REVERSE DNS i.e by knowing the ip address u can know the hosts
name.

Guys this website also does the same info as above with the difference that, it also
shows where u are exactly on the geographical map.
just check it man it would be more clear to u.

Eg: for www.nettech.in the details are as follows:

Host info:
--------------
Host of the IP: www.nettech.in
Host IP: 202.144.75.66
