It's misconfigured in that gethostbyname() returns NULL:

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.
