whois for domains?

I need to find a whois for someone who owns a site.

I only know two of his websites but I need to know of all of the domains he owns.

Where is that tool?

 

try domaintools.com. whois is free.
its a paid service for the reports on other domains etc though.

 

Yeah, but the only problem is it will not tell me which domains are by the same person who registered it.

It just says the amount of domains.

 

You can get the details of other domain name also, but I am scared that is a paid service by them.

 

It is paid. It was $156 bucks.

That's stupid that those idiots would charge for something so automatic. Anyone know anywhere else?

 

This is what your looking for and its free

yougetsignal.com/tools/web-sites-on-web-server/

 

I use sometimes Project Whois. Very good tools. You can see lot of informations.

Best Regards!
