=head1 DESCRIPTION

Class for DNS Canonical Name (CNAME) 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 cname

    $cname = $rr->cname;
    $rr->cname( $cname );

A domain name which specifies the canonical or primary name for
the owner.  The owner name is an alias.
