This works fine... 
   print $name = gethostbyaddr(192.168.1.1, AF_INET);

This does not...
   while (defined($line = <INPUT>)) {

    if ($line =~ /\b\d*\.\d*\.\d*\.\d*\b/) {
        $name = gethostbyaddr($&, 'tcp');

        if (defined($name)) {
            print "hostname for address $&: $name\n";

        }else{
            print "Couldn't get hostname for: $&\n";
        }
    }
}

The value of $& appears to be the correct ip address, but for some reason gethostbyaddr() isn't returning a defined value. My guess is that the value in $& isn't formatted correctly for the function to correctly pass it.

What am I missing (besided pretty code)?
