exactly - as long as the PTR record exists and returns a FQHN with a
resolvable and identical A record, rfc1912 seems satisfied.

back to the thread, I wouldn't feel comfortable with using PTR
nonexistence (or otherwise) to prove that an address is no longer used.
After all, that address *is* about to be used (hence the problem). In
other words, you'd have to violate rfc1912 on an authoritative nameserver
(of all devices to violate it on) just to prove re-use.
