reverse (just one possible):
This is a bit off topic, but I've seen multiple PTR records for one ip

for example 64.251.192.200 has 245 different PTR records. I can't help but
think this is violating some established practice somewhere.
I know that powerdns does just this (reverse my server's IP,
206.168.112.32 and see). I think it actually works in the vast majority
of cases, though once you get up into the hundreds of names, it pushes
you completely into the realm of TCP DNS.
I suspect that PowerDNS setups are one of the primary places this
occurs.
