I think you are making a mistake here but it is probably a typo? 
unpack("a4", inet_ntoa($buffer);

Also have you tried doing this on the same machine? 
my $buf,$str;
my $ip_addr="10.10.10.1";
$buf=pack("a4",inet_aton($ip_addr));
$str=inet_ntoa(unpack("a4",$buf));
print "$str\n";

Do you get the correct address after doing this? If you do perhaps you are misconfiguring your setup to transmit the bytes over the socket?
