That's not always reliable. For example, if you do a query on my company's web server IP address, you'll just get the name of our ISP as your result.

Whois on an IP address - you mean rDNS, right? Are you sending mail from this server without fcrdns?

Most VPS providers will let you change the rDNS record for the IP.
