NAME
    Net::DNS::RR::AMTRELAY - DNS AMTRELAY resource record

SYNOPSIS
        use Net::DNS;
        $rr = Net::DNS::RR->new('owner AMTRELAY precedence Dbit relaytype relay');

DESCRIPTION
    AMTRELAY resource record designed to permit DNS Reverse IP AMT Discovery
    (DRIAD), a mechanism for AMT gateways to discover AMT relays that are
    capable of forwarding multicast traffic from a known source IP address.

    AMT (Automatic Multicast Tunneling) is defined in RFC7450 and provides a
    method to transport multicast traffic over a unicast tunnel in order to
    traverse network segments that are not multicast capable.

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.

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

    8-bit integer which indicates relative precedence within the RRset.
    Relays listed in AMTRELAY records with lower precedence are to be
    attempted first.

  Dbit, Discovery Optional
        $Dbit = $rr->Dbit;
        $rr->Dbit(1);

    Boolean field which indicates that the gateway MAY send an AMT Request
    message directly to the discovered relay address without first sending
    an AMT Discovery message.

  relaytype
        $relaytype = $rr->relaytype;

    The relaytype type field indicates the format of the information that is
    stored in the relay field.

    The following values are defined:

        0: The relay field is empty (0 bytes).

        1: The relay field contains a 4-octet IPv4 address.

        2: The relay field contains a 16-octet IPv6 address.

        3: The relay field contains a wire-encoded domain name.

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

    The relay field is the address or domain name of the AMT relay. It is
    formatted according to the relaytype field.
