updated definitions of existing query types that return Internet addresses as
part of additional section processing.
•
The extensions are compatible with existing applications and, in particular,
DNS implementations themselves.
•
RFC 2874: DNS Extensions to Support IPv6 Address Aggregation and
Renumbering
•
Changes are made to DNS to support aggregated and renumbered IPv6
addressing.
•
A new RR type, A6, maps a domain name to an IPv6 address, with a provision
for indirection for leading prefix bits.
•
A new domain, IP6.ARPA, supports lookups based on IPv6 addresses.
•
The new scheme for reverse lookups relies on a new type of DNS label called
the bit-string label [BITLBL], which represents an arbitrary string of bits that is
treated as a hierarchical sequence of one-bit domain labels.
•
DNS address-space delegation is implemented by a new analogue to the
CNAME record, called the DNAME RR, which provides alternate naming to an
entire subtree of the domain-name space, rather than to a single node.
•
RFC 2845: Secret Key Transaction Authentication for DNS (TSIG)
•
Allows for transaction-level authentication using shared secrets and one-way
hashing.
•
It can be used to authenticate dynamic updates as coming from an approved
client, or to authenticate responses as coming from an approved recursive
Name Server.
