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.
