Net::DNS::RR::AMTRELAY(3pm) User Contributed Perl Documentation Net::DNS::RR::AMTRELAY(3pm)
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.
