+1, also a quick check to make sure your name servers are actually set
can be done with host.. host -t ns 0.168.192.in-addr.arpa

I suggest doing something like:
dig +trace -x 204.42.254.5
You can watch the delegation authority for the in-addr at each stage.

We have a /24 from one of our upstream providers that we handoff to a customer.
The /24 has been SWIPd to us, and we have nameservers setup with ARIN against
that record.
Twice now this information has just "disappeared". That is, if do reverse DNS
lookups, they returns nothing, whereas they were just working fine earlier. If you do an
NS lookup on the block, it returns nothing. The /24 blocks immediately surrounding us
continue to work just fine. If we do a lookup directly against our nameserver, it works
just fine.
It's like the nameserver information against that reverse DNS is just magically
gone.
The ARIN record looks good, nothing has changed. Last time, our upstream
resubmitted the info so it would repopulate, and it started working again soon
there after. I admit to not being the smartest one with how these records
work: is the problem with the upstream, or ARIN's database, or is there not
enough information to tell?
Thanks,
