Abstract

   This document defines changes to the Domain Name System to support
   renumberable and aggregatable IPv6 addressing.  The changes include a
   new resource record type to store an IPv6 address in a manner which
   expedites network renumbering and updated definitions of existing
   query types that return Internet addresses as part of additional
   section processing.

   For lookups keyed on IPv6 addresses (often called reverse lookups),
   this document defines a new zone structure which allows a zone to be
   used without modification for parallel copies of an address space (as
   for a multihomed provider or site) and across network renumbering
   events.
