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.
