14 Delegation of IP6.ARPA
18 This document specifies an Internet Best Current Practices for the
19 Internet Community, and requests discussion and suggestions for
20 improvements. Distribution of this memo is unlimited.

28 This document discusses the need for delegation of the IP6.ARPA DNS
29 zone, and specifies a plan for the technical operation thereof.
33 In the IPv6 address space, there is a need for 'reverse mapping' of
34 addresses to DNS names analogous to that provided by the IN-ADDR.ARPA
37 The IAB recommended that the ARPA top level domain (the name is now
38 considered an acronym for "Address and Routing Parameters Area") be
39 used for technical infrastructure sub-domains when possible. It is
40 already in use for IPv4 reverse mapping and has been established as
41 the location for E.164 numbering on the Internet [RFC2916 RFC3026].
43 IETF consensus was reached that the IP6.ARPA domain be used for
44 address to DNS name mapping for the IPv6 address space [RFC2874].
48 This document deprecates references to IP6.INT in [RFC1886] section
49 2.5, [RFC2553] section 6.2.3, [RFC2766] section 4.1, [RFC2772]
50 section 7.1.c, and [RFC2874] section 2.5.
52 In this context, 'deprecate' means that the old usage is not
53 appropriate for new implementations, and IP6.INT will likely be
54 phased out in an orderly fashion.

63 3. IANA Considerations
65 This memo requests that the IANA delegate the IP6.ARPA domain
66 following instructions to be provided by the IAB. Names within this
67 zone are to be further delegated to the regional IP registries in
68 accordance with the delegation of IPv6 address space to those
69 registries. The names allocated should be hierarchic in accordance
70 with the address space assignment.
72 4. Security Considerations
74 While DNS spoofing of address to name mapping has been exploited in
75 IPv4, delegation of the IP6.ARPA zone creates no new threats to the
76 security of the internet.
