Try http://whois.webhosting.info

The info is cached, so it's dated. But for instance:

shows that ubuntu.com is on and that IP hosts 122 domains.

So now we look at:
and you can see what those 122 domains are.

Now if I look at the IP of one of the domain servers used by ubuntu.com:
I can see about 418 domains.

 From the terminal you can also see what other nameservers might share a 

$ whois -h whois.nsiregistry.com

man whois for the -h option etc.

I know of no other non abusive way to do this directly.
