This is a bit off topic, but I've seen multiple PTR records for one ip address,
for example 64.251.192.200 has 245 different PTR records. I can't help but

It is... While it's not necessarily against the RFC AFAIK, the Cricket book (4th edition) says use ONE PTR record and it should point at the canonical name only.
