It should be simple to build a DNS server that will automatically generate a hostname value for every reverse lookup received, and also be able to parse that hostname value to return the correct IPv6 address on forward lookups. Does any DNS server have that feature? Should we have it? Why not?
Nominum's nameserver software has these features. Industrial strength nameservice, with lots of industrial-strength features, but at an industrial-strength price. I thought BIND had grown that feature, but I haven't used BIND for a while now, so maybe not.
1b) anti spam filters believe in the magic of checking forward/reverse match.
Someone in this thread said that only malware-infested end-users are behind IP addresses with no reverse lookup. Well - no. As long as we keep telling anyone who isn't running a full-bore commercial network to "consume, be silent, die", we are holding everyone back, including ourselves. It's fine to use no-reverse-lookup as a component of a spamminess score. It's not OK to use it as proof of spamminess.
