A client of mine just discovered that he could no longer do ftp transfers to my machine. His IP address had changed to one in 12.240.20 and there is no reverse DNS for that block. His previous assignment was in a totally different block which did have reverse DNS. Calls to ATTBI got the answer that they are not obligated to provide reverse DNS and have no plans to do so. My servers refuse connections when there is no reverse lookup.
Is this common?
yes, i've had similar problems with cox both when i had cox@work business service, and now that i have cox@home residential service. this feeds right into the thread that branched off my post about "network diameter" in which people are talking about "clue factor". these networks spring up overnight, built by people who are missing some of the fundamental knowledge about how all this "stuff" works. and we're stuck with it as end users. -b
