The WHOIS database is a nice way to determine contact information for a web site. Query the site with whois <site> It shows the name and address of the registrant, through who he/she registered the site, a technical and administrative contact, and the domain servers corresponding to the site. Use it along with dig, host, ping, etc. (and if you're feeling naughty, nmap) to get information about a site.
