Subject Re: reverse IP lookup for check all doimains on the server
Date Tue, 15 Jun 2004 12:12:37 GMT


Looks like they have created their own database.  It's
not all that accurate either.  I have a few IPs with websites on
them which just turned up "no data available".

For example, www.perl.org is on 63.251.223.172
but it does not come up at http://whois.webhosting.info/63.251.223.172
