As far as I'm aware all bulletin boards store the IP addresses of users, PHPBB (the previous software) gives a list of every IP address a user has posted from, this software gives just one IP address. Presumably if you have a dynamic IP address (as most users do) it will give the last one used?, or perhaps blank it? (like the ones in question).
Incidently, your reverse DNS gives 'United States [City: Englewood, Colorado]'.
Just checked mine!, that's blank as well - but I logon from both work (fixed IP) and home (dynamic IP).
As far as I'm aware the owner is in New Zealand?, the domain name is registered through "COMPUTER SERVICES LANGENBACH GMBH DBA JOKER.COM", and the registered owner is "Phil G, Oxfordshire, England" - this is all freely available via "whois". A 'trace route' takes you to Abacus America Inc. in San Deigo - presumably it's them who do the hosting?.
I, I, feel nothing. What is this vast empty hole? Could it be? No! Is it the horror of knowing? The nothingness that lingers in my head? YES! It is! No! It is almost blinding...
