Not only is Net::DNS overkill, but using Net::DNS means you're committed to using DNS to do the domain name resolving. While that may work on many machines, gethostbyaddr will actually use the resolving that's configured for the system. Which, beside DNS, may consist of files, NIS, NIS+, LDAP, ... or some combination of resolving.
