NAME

6       Net::DNS::RR::AMTRELAY - DNS AMTRELAY resource record
7

SYNOPSIS

9           use Net::DNS;
10           $rr = Net::DNS::RR->new('owner AMTRELAY precedence Dbit relaytype relay');
11

DESCRIPTION

13       AMTRELAY resource record designed to permit DNS Reverse IP AMT
14       Discovery (DRIAD), a mechanism for AMT gateways to discover AMT relays
15       that are capable of forwarding multicast traffic from a known source IP
16       address.
17
18       AMT (Automatic Multicast Tunneling) is defined in RFC7450 and provides
19       a method to transport multicast traffic over a unicast tunnel in order
20       to traverse network segments that are not multicast capable.
21

METHODS

23       The available methods are those inherited from the base class augmented
24       by the type-specific methods defined in this package.
25
26       Use of undocumented package features or direct access to internal data
27       structures is discouraged and could result in program termination or
28       other unpredictable behaviour.
29
30   precedence
31           $precedence = $rr->precedence;
32           $rr->precedence( $precedence );
33
34       8-bit integer which indicates relative precedence within the RRset.
35       Relays listed in AMTRELAY records with lower precedence are to be
36       attempted first.
37
38   Dbit, Discovery Optional
39           $Dbit = $rr->Dbit;
40           $rr->Dbit(1);
41
42       Boolean field which indicates that the gateway MAY send an AMT Request
43       message directly to the discovered relay address without first sending
44       an AMT Discovery message.
45
46   relaytype
47           $relaytype = $rr->relaytype;
48
49       The relaytype type field indicates the format of the information that
50       is stored in the relay field.
51
52       The following values are defined:
53
54           0: The relay field is empty (0 bytes).
55
56           1: The relay field contains a 4-octet IPv4 address.
57
58           2: The relay field contains a 16-octet IPv6 address.
59
60           3: The relay field contains a wire-encoded domain name.
61
62   relay
63           $relay = $rr->relay;
64           $rr->relay( $relay );
65
66       The relay field is the address or domain name of the AMT relay.  It is
67       formatted according to the relaytype field.
