Abstract

   This document clarifies and updates the standards status of RFCs that
   define direct and reverse map of IPv6 addresses in DNS.  This
   document moves the A6 and Bit label specifications to experimental
   status.

1.  Introduction

   The IETF had begun the process of standardizing two different address
   formats for IPv6 addresses AAAA [RFC 1886] and A6 [RFC 2874] and both
   are at proposed standard.  This had led to confusion and conflicts on
   which one to deploy.  It is important for deployment that any
   confusion in this area be cleared up, as there is a feeling in the
   community that having more than one choice will lead to delays in the
   deployment of IPv6.  The goal of this document is to clarify the
   situation.

   This document also discusses issues relating to the usage of Binary
   Labels [RFC 2673] to support the reverse mapping of IPv6 addresses.

   This document is based on extensive technical discussion on various
   relevant working groups mailing lists and a joint DNSEXT and NGTRANS
   meeting at the 51st IETF in August 2001.  This document attempts to
   capture the sense of the discussions and reflect them in this
   document to represent the consensus of the community.
