Technical Summary DHCPv6 "leasequery" allows a DHCPv6 server to be queried for information about DHCPv6 bindings. As an example, a network element may use leasequery to recover state derived from DHCP message exchanges. The existing leasequery mechanism is limited to queries for individual bindings. In some situations individual binding queries may not be efficient, or even possible. DHCPv6 bulk leasequery expands on the Leasequery protocol, adding new query types and allowing for bulk transfer of DHCPv6 binding data via TCP. Working Group Summary The dhc WG reviewed this document and raised several issues during the WG last call. All of the issues have been resolved or addressed in this revision of the draft. One set of issues was raised in http://www.ietf.org/mail-archive/web/dhcwg/current/msg08468.html; the issues were resolved in a revision to the draft. Document Quality DHCPv6 bulk leasequery was originally developed as a simple extension to DHCPv6 leasequery, carried over UDP. Because of the possible effect on the network of a bulk data transfer over UDP, DHCPv6 bulk leasequery was re-architected to use TCP. The specification for the resulting protocol has been reviewed by both dhc WG members and external transport experts. DHCPv6 bulk leasequery was originally developed at the request of a large ISP, in anticipation of IPv6 service deployment. At least one DHCPv6 server vendor plans to implement DHCPv6 bulk leasequery. Personnel Jari Arkko has reviewed this specification for the IESG.
