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.

Right. Like I said, this is a starting point and won't necessarily give the final answer. But, you can find out who is responsible for the IP and work your way down by contacting them. (They might even have their own whois server.) I do think the guy's client should have a look at his records to see who he is paying... but, there's always the possibility he paid for a year up front 6 months ago and has since lost the info, closed his bank account, changed banks, paid with a money order initially, or whatever.
