Your DNS server should have 2 files, one that does ip->name and one that does name->ip. For exmaple I take care of monadlug.org and I have db.monadlug that contains any/all hosts in that domain. Then I have a db.43.22.207 file that includes reverse mappings, with records like this:
150 IN PTR talisman.monadlug.org. In my case I serve several domains from one machine and I only have 1 reverse lookup file.
