Hmmno thanks. I already have a job, and though it has its ups and downs, I'm not looking for another :).
You're still free to keep asking questions to the monks in general though.

Edit: Cleaned up code and perltidy'd it. There seems to be a bug in Net::DNS::Packet where, if you remove the debug-flag when creating a new packet object from raw data, the answer section doesn't get decoded.

use strict;
use warnings;
use AnyEvent::Handle::UDP;
use Socket;
use Net::DNS::Packet;
use Data::Dump;

my $target_host = shift;
if (!defined $target_host) {
    print ("Usage: $0 hostname\n");
    exit 1;
}

my $d = Net::DNS::Packet->new($target_host, "PTR");

my $cv_recv = AnyEvent->condvar;
my $t = AnyEvent::Handle::UDP->new(
    timeout    => 3,
    on_timeout => sub {
        print STDERR "Nothing happened within the specified timeout ti
+meframe...\n";
    },
    on_error => sub {
        print STDERR "An error has occurred:";
        Data::Dump::dd(@_);
    },
    on_recv => sub {
        my ($buf, $handle) = @_;
        my ($res, $err) = Net::DNS::Packet->new(\$buf,1);
        if ($err) {
            print STDERR $err . "\n";
        } else {
            Data::Dump::dd($res);
        }
        $cv_recv->send;
    },
);

$t->bind_to(['0.0.0.0', 0]);
my $cv_send = $t->push_send($d->data, pack_sockaddr_in(53, Socket::ine
+t_aton('IP_OF_DNS-SERVER_HERE')));
print ("Waiting for data to be sent...");
$cv_send->recv;
print ("[OK]\n");

print ("Waiting for data to arrive...");
$cv_recv->recv;
print ("[OK]\n");
