Net::DNS::RR::AMTRELAY - DNS AMTRELAY resource record
use Net::DNS; $rr = Net::DNS::RR->new('owner AMTRELAY precedence D relaytype relay');
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.
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 = $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.
$D = $rr->D; $rr->D(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 = $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 = $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.
