   Does anyone know how to obtain the hostname of a machine given the IP

including automatic in-addr.arpa queries when given a dotted quad, no
need to do special "query=ptr" things.

You can pick it up as tut.cis.ohio-state.edu:pub/nameserver/host.[1c].
Chuck Hedrick/Rutgers is responsible for it.
