=head1 SYNOPSIS

use Net::DNS;
    $rr = new Net::DNS::RR('name AFSDB subtype hostname');

=head1 DESCRIPTION

Class for DNS AFS Data Base (AFSDB) 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 subtype

$subtype = $rr->subtype;

A 16 bit integer which indicates the service offered by the
listed host.

=head2 hostname

$hostname = $rr->hostname;

The hostname field is a domain name of a host that has a server
for the cell named by the owner name of the RR.
