Where would the info have to be available?  Is there anything comparable to
a "dig -x" command under Unix?  For most IP addresses, there will not be
anything configured on my computer, but I know that ARPA reverse lookups are
possible.

The method you show above still returns the IP address on my system, yet a
"dig -x" will show the host name resolved.
