advises of the deprecation of the use of "ip6.int" for
Standards Conformant IPv6 implementations.
1. IPv6 Standards Action
In August 2001
the IETF published [RFC3152], which advised that the
use of "ip6.int" as the domain for reverse-mapping of IPv6 addresses
to DNS names was deprecated. The document noted that the use of
"ip6.int" would be phased out in an orderly fashion.
As of 1
September 2005, the IETF advises the community that the DNS
domain "ip6.int" should no longer be used to perform reverse mapping
of IPv6 addresses to domain names, and that the domain "ip6.arpa"
should be used henceforth, in accordance with the IANA Considerations
described in [RFC3596]. The domain "ip6.int" is deprecated, and its
use in IPv6 implementations that conform to the IPv6 Internet
Standards is discontinued.
Internet Registries (RIRs) are advised that maintenance
of delegation of entries in "ip6.int" is no longer required as part
of infrastructure services in support of Internet Standards
Conformant IPv6 implementations as of 1 September 2005. The RIRs are
requested to work with their communities to adopt a schedule
regarding the cessation of support of registration services for the
Huston Best Current Practice [Page 1]

2. IANA Considerations
IANA is advised
that the "ip6.int" domain for reverse mapping of IPv6
addresses to domain names is no longer part of Internet Standards
Conformant support of IPv6 as of 1 September 2005.
3. Security Considerations
spoofing of address to name mapping has been exploited in
IPv4, removal of the "ip6.int" zone from the standard IPv6
specification creates no new threats to the security of the internet.
