I'm resolving ip addresses to host names based upon the following: 
#!/usr/bin/perl -w
use strict;
use Socket;

foreach my $ip (@ARGV) 
{
  my $sin = inet_aton($ip);
  my $name = gethostbyaddr $sin, AF_INET;
  print "$ip => $name\n";
}

This works but I would like to change the server it uses to resolve the ip from within the code. My research has proved futile.
