There's also "host_name_lookup()" for translating IP addresses to names
- or, if no name could be found, dotted-quad IP address strings.

On *some* platforms, at least, there are also routines to translate MAC
addresses to host names, if you have such a database handy; a routine
that, if such a routine is handy, uses it, and if it's missing or if the
attempt to use it failed, does "ether_to_str()", might be handy as well.
