public class Inet6AddressRecordEncoder
extends Object
2. New resource record definition and domain
A record type is defined to store a host's IPv6 address. A host that
has more than one IPv6 address must have more than one such record.
2.1 AAAA record type
The AAAA resource record type is a record specific to the Internet
class that stores a single IPv6 address.
The IANA assigned value of the type is 28 (decimal).
2.2 AAAA data format
A 128 bit IPv6 address is encoded in the data portion of an AAAA
resource record in network byte order (high-order byte first).
2.3 AAAA query
An AAAA query for a specified domain name in the Internet class
returns all associated AAAA resource records in the answer section of
a response.
A type AAAA query does not trigger additional section processing.
2.4 Textual format of AAAA records
The textual representation of the data portion of the AAAA resource
record used in a master database file is the textual representation
of an IPv6 address as defined in [3].
2.5 IP6.ARPA Domain
A special domain is defined to look up a record given an IPv6
address. The intent of this domain is to provide a way of mapping an
IPv6 address to a host name, although it may be used for other
purposes as well. The domain is rooted at IP6.ARPA.
An IPv6 address is represented as a name in the IP6.ARPA domain by a
sequence of nibbles separated by dots with the suffix ".IP6.ARPA".
The sequence of nibbles is encoded in reverse order, i.e., the
low-order nibble is encoded first, followed by the next low-order
nibble and so on. Each nibble is represented by a hexadecimal digit.
For example, the reverse lookup domain name corresponding to the
address
4321:0:1:2:3:4:567:89ab
would be
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.
ARPA.
