=head1 SYNOPSIS

use Net::DNS;
    $rr = new Net::DNS::RR('name IN HIP algorithm hit key servers');

=head1 DESCRIPTION

Class for DNS Host Identity Protocol (HIP) 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 pkalgorithm

$pkalgorithm = $rr->pkalgorithm;

The PK algorithm field indicates the public key cryptographic
algorithm and the implied public key field format.
The values are those defined for the IPSECKEY algorithm type [RFC4025].

=head2 hit

$hit = $rr->hit;

The hexadecimal representation of the host identity tag.

=head2 hitbin

$hitbin = $rr->hitbin;

The binary representation of the host identity tag.

=head2 key

$key = $rr->key;

The hexadecimal representation of the public key.

=head2 keybin

$keybin = $rr->keybin;

The binary representation of the public key.

=head2 servers

@servers = $rr->servers;

Optional list of domain names of rendezvous servers.
