OK, that might explain it then. I'm going to guess that I'm seeing more IP's that don't have a rDNS record. If I understand it right then, from the way you've explained it - getnameinfo() must use the rDNS. Am I correct in assuming that the rDNS info (host name in this case) is different than the info returned from a WHOIS query? Because I've found that I can still get the "owner info" on the IP addresses that fail getnameinfo().
