The best way to do this is to have the person who is primary for 166.1.199.in-addr.arpa insert records like: jdl IN NS jdl.com. 200 IN CNAME 200.jdl 201 IN CNAME 201.jdl 202 IN CNAME 202.jdl ... 207 IN CNAME 207.jdl And then you can build a database for jdl.166.1.199.in-addr.arpa and you can be authoritative. I am sure that this is documented somewhere but can't figure out where. The most recent time I heard it described was at the NANOG meeting a month or so ago, and the person describing it said that people have been doing this for years. >Meta-question: Is there a better DNS list to question for this one? comp.protocols.tcp-ip.domains is probably a good place.
