The IESG has approved the Internet-Draft 'DNS Extensions to Support IP Version 6' <draft-ietf-ipngwg-dns-lookups-08.txt> as a Proposed Standard. This document is the product of the IPNG Working Group. The IESG contact persons are Erik Nordmark and Thomas Narten.

Technical Summary

This document defines changes to the Domain Name System to support renumberable and aggregatable IPv6 addressing. The changes include a new resource record type (called A6) to store an IPv6 address in a manner that expedites network renumbering and updated definitions of existing query types that return Internet addresses as part of additional section processing. A6 records can hold all or part of an address, with pointers to other DNS names holding the remaining part of the address.

For lookups keyed on IPv6 addresses (often called reverse lookups), this document defines a new zone structure that 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.

Working Group Summary

This document was discussed extensively in both the IPNG and DNSIND working groups. Although concern has been raised that use of the A6 records will increase the demands placed on the DNS when resolving names to addresses, the goal of easing site renumbering was deemed important and the mechanism described in this document was viewed as the best approach.

Protocol Quality

This document has been reviewed for the IESG by Thomas Narten and Erik Nordmark.
