=head1 SYNOPSIS

    use Net::DNS;
    $rr = new Net::DNS::RR('name RP mbox txtdname');

=head1 DESCRIPTION

Class for DNS Responsible Person (RP) 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 mbox

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

A domain name which specifies the mailbox for the person responsible for
this domain. The format in master files uses the DNS encoding convention
for mailboxes, identical to that used for the RNAME mailbox field in the
SOA RR. The root domain name (just ".") may be specified to indicate that
no mailbox is available.

=head2 txtdname

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

A domain name identifying TXT RRs. A subsequent query can be performed to
retrieve the associated TXT records. This provides a level of indirection
so that the entity can be referred to from multiple places in the DNS. The
root domain name (just ".") may be specified to indicate that there is no
associated TXT RR.
