This black list company seems to be a shoddy operation. They have blacklisted the entire subnet to which we belong, and there does not appear to be a way to contact them to get off the list. Their web site is hard to navigate, and appears to be an advertisement for custom software development.
I have contacted our ISP, and asked them to look into this, but have not as yet heard a reply. The complaints detailed on the five-ten-sg web site appear to indicate that there is a problem in the way our ISP, Time Warner Road Runner, appears to list our IP subnet, bother reverse DNS lookup and A record lookup, but is not clear on how to fix the problem.
Has anyone else run into this problem, and is there a way to contact this black list to get our IP sibnet removed, or at least our IP?
