Having looked at the draft, I agree that its complexity and the multiple changes it makes to exisitng DNS semantics make it dead on arrival. My suggestion if you really want to do this is to use a specialized server. People who serve DNSBLs use a specialized server called rbldnsd. You give it CIDR ranges of addresses and it synthesizes DNSBL records, including patching the addresses into TXT records so they can return stuff like this: 4.3.2.1.bl.bad.example TXT "Blocked -- see http://www.bad.example?ip=1.2.3.4" where the 1.2.3.4 was plugged in on the fly. rDNS and DNSBLs are quite similar in DNS function, so you could probably modify rbldnsd to generate PTR records with patterns in the same way. Then just delegate your rDNS zones to it. Since v6 rDNS breaks names on 4-bit boundaries, even if your delegations are rather irregular, it's not all that many delegations.
