=head1 SYNOPSIS

    use Net::DNS;
    $rr = new Net::DNS::RR('name DNAME target');

=head1 DESCRIPTION

Class for DNS Non-Terminal Name Redirection (DNAME) 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 target

    $target = $rr->target;

Redirection target domain name which is to be substituted
for its owner as a suffix of a domain name.
