=head1 SYNOPSIS

use Net::DNS;
    $rr = new Net::DNS::RR('name IN AAAA address');

$rr = new Net::DNS::RR(
	name	=> 'example.com',
	type	=> 'AAAA',
	address => '2001:DB8::8:800:200C:417A'
	);

=head1 DESCRIPTION

Class for DNS IPv6 Address (AAAA) resource records.

=head1 METHODS

The available methods are those inherited from the base class augmented
by the type-specific methods defined in this package.

Use of undocumented package features or direct access to internal data
structures is discouraged and could result in program termination or
other unpredictable behaviour.

=head2 address

$IPv6_address = $rr->address;

Returns the text representation of the IPv6 address.

=head2 address_long

$IPv6_address = $rr->address_long;

Returns the text representation specified in RFC3513, 2.2(1).

=head2 address_short

$IPv6_address = $rr->address_short;

Returns the textual form of address recommended by RFC5952.
