Domain Hacking

[Bjfox]

If i understand the question and i may not you want to know how to make a domain like surf.pin.net well thats easy. You need to either own pin.net or be able to get a subdomain of it thus surf.pin.net.
As far as i am aware that is the only way you can do it.
As for the next bit. namehere.surfpin is the same thing namehere.surfpin.net
The namehere would be the sub domain.

This is true, he beat me to it but ya basically you need to own the website to make a sub domain.. if u own the domain and your hosting provides cpanel its very easy
