25 * 2. New resource record definition and domain
26 *
27 * A record type is defined to store a host's IPv6 address. A host that
28 * has more than one IPv6 address must have more than one such record.
29 *
30 * 2.1 AAAA record type
31 *
32 * The AAAA resource record type is a record specific to the Internet
33 * class that stores a single IPv6 address.
34 *
35 * The IANA assigned value of the type is 28 (decimal).
36 *
37 * 2.2 AAAA data format
38 *
39 * A 128 bit IPv6 address is encoded in the data portion of an AAAA
40 * resource record in network byte order (high-order byte first).
41 *
42 * 2.3 AAAA query
43 *
44 * An AAAA query for a specified domain name in the Internet class
45 * returns all associated AAAA resource records in the answer section of
46 * a response.
47 *
48 * A type AAAA query does not trigger additional section processing.
49 *
50 * 2.4 Textual format of AAAA records
51 *
52 * The textual representation of the data portion of the AAAA resource
53 * record used in a master database file is the textual representation
54 * of an IPv6 address as defined in [3].
55 *
56 * 2.5 IP6.ARPA Domain
57 *
58 * A special domain is defined to look up a record given an IPv6
59 * address. The intent of this domain is to provide a way of mapping an
60 * IPv6 address to a host name, although it may be used for other
61 * purposes as well. The domain is rooted at IP6.ARPA.
62 *
63 * An IPv6 address is represented as a name in the IP6.ARPA domain by a
64 * sequence of nibbles separated by dots with the suffix ".IP6.ARPA".
65 * The sequence of nibbles is encoded in reverse order, i.e., the
66 * low-order nibble is encoded first, followed by the next low-order
67 * nibble and so on. Each nibble is represented by a hexadecimal digit.
68 * For example, the reverse lookup domain name corresponding to the
69 * address
70 *
71 * 4321:0:1:2:3:4:567:89ab
72 *
73 * would be
74 *
75 * b.a.9.8.7.6.5.0.4.0.0.0.3.0.0.0.2.0.0.0.1.0.0.0.0.0.0.0.1.2.3.4.IP6.
76 * ARPA.
