You can simply use
my $addr = gethostbyname($hostname);
instead of
my $addr = (gethostbyname($hostname))[4];
When used in scalar context, gethostbyname returns the address, which would have prevented your earlier bug.

    This is what I did at first, that was the problem (if you look at my original post). what's the difference?

      You weren't unpacking the address.

      You still need to unpack the results.

      A complete example would be:

      my $hostname = 'yahoo.com';
my $addr = gethostbyname($hostname);
my ($a,$b,$c,$d) = unpack('C4',$addr);
print "$a.$b.$c.$d\n";
