=head1 DESCRIPTION

=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 ptrdname

    $ptrdname = $rr->ptrdname;

A domain name which points to some location in the
domain name space.
