Whois. Either type it at the command line on most *nix systems, or go here.

    That will tell me who registered it, but will it tell me which company is hosting it? What if the person who has registered it has forgotten who they registered it with and who they got to host the site?

      A good place to start might be to use whois to check the IP with arin.net: whois -h whois.arin.net xxx.xxx.xxx.xxx. That won't necessarily give you the final answer though. The best way would simply to ask your client to check who his payments are being made to.

        This doesn't work, either. In my case, I get some company I've never heard of, which is most likely whoever hosts the company that hosts me. I think your best chance is to do as others have suggested - ask the company to check who they're paying. Low-tech, but if it works...

      Look at the DNS servers, those are almost certainly provided by the host. Do a Whois on those.

        That's simply not true. DNS is very often provided by the registrar or the host's host (or the host's host's host, etc.) in the case of resellers. And it could also be provided by a third party contracted by the host.

      sauoq gave the correct answer; you want to do a whois on the IP address of the box. Traceroute will give you hints, but whois on an IP address is the authoritative answer.
