I didn't say the DNS record has to be anything specific, it just has to exist.
Almost all ISPs have a reverse DNS record for every IP, they commonly
indicate the type or location of the address.
Case in point (comcast):
126.96.36.199.in-addr.arpa domain name pointer
The problem arises usually when a private address is used where no
reverse DNS zone is served at all.
This means you either need to synchronize a complete hosts list to all
machines, or run your own internal DNS server.
