Ok, I was wrong about top level stuff... My point was that you don't register every box at like register.com, you only register secondlevel.. Register.com only checks second level (I guess), while php queries the name on some dns server, which gives php another dns server and so on, until it finds what it's looking for... Gah, jusst forget I even started typing this message, I have no real idea what I'm talking about...
