nameserver

Up until now, I was pretty confident that it was pretty much impossible to list all the domains handled by a nameserver.

But apparently, there exists a couple of websites on the Internet that are able to list all the domains registered in a namerserver.

For example:

http://www.gwebtools.com/ns-spy/udns1.ultradns.net

Or all domains pointing to a specific IP :

http://www.robtex.com/ip/190.7.200.92.html

(These DNS/IP were picked at random)

Do you know how it's done ?
