+ Delegation of IP6.ARPA
+
+Status of this Memo
+
+ This document specifies an Internet Best Current Practices for the
+ Internet Community, and requests discussion and suggestions for
+ improvements. Distribution of this memo is unlimited.

+
+Abstract
+
+ This document discusses the need for delegation of the IP6.ARPA DNS
+ zone, and specifies a plan for the technical operation thereof.
+
+1. Why IP6.ARPA?
+
+ In the IPv6 address space, there is a need for 'reverse mapping' of
+ addresses to DNS names analogous to that provided by the IN-ADDR.ARPA
+ zone for IPv4.
+
+ The IAB recommended that the ARPA top level domain (the name is now
+ considered an acronym for "Address and Routing Parameters Area") be
+ used for technical infrastructure sub-domains when possible. It is
+ already in use for IPv4 reverse mapping and has been established as
+ the location for E.164 numbering on the Internet [RFC2916 RFC3026].
+
+ IETF consensus was reached that the IP6.ARPA domain be used for
+ address to DNS name mapping for the IPv6 address space [RFC2874].
+
+2. Obsoleted Usage
+
+ This document deprecates references to IP6.INT in [RFC1886] section
+ 2.5, [RFC2553] section 6.2.3, [RFC2766] section 4.1, [RFC2772]
+ section 7.1.c, and [RFC2874] section 2.5.
+
+ In this context, 'deprecate' means that the old usage is not
+ appropriate for new implementations, and IP6.INT will likely be
+ phased out in an orderly fashion.

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