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.
