Here's an 'nslookup' on your stuff: | > set q=any | > 11.2.125.199.in-addr.arpa. | Server: ns.lambert.org | Address: 198.17.250.50 | | 11.2.125.199.in-addr.arpa name = webserver.id.net | 2.125.199.in-addr.arpa nameserver = ns1.id.net | 2.125.199.in-addr.arpa nameserver = ns2.id.net | ns1.id.net internet address = 199.125.1.1 | ns2.id.net internet address = 199.125.1.2 Offhand, I'd say that this was entirely too much stuff to be returned for an RARP entry. I'd expect something like a single line of: | 11.2.125.199.in-addr.arpa name = webserver.id.net I'd also expect, on a forward lookup, something like: | > www001.id.net | www001.id.net canonical name = webserver.id.net instead of a huge amount of cruft. The cruft won't really hurt (probably), but it's indicative of no logical seperation of SOA and namedb records. THEN I'd expect the huge amount of cruft for the CNAME record for a forward on "webserver.id.net". Probably the lack of a "cannonical name" (CNAME) record is why it's failing to find the cannonical name. You probably have the numeric value listed multiple times instead of using alias (A) records, if I had to guess.
