Active DHCPv4 Lease Query
Draft of message to be sent after approval:
From: The IESG <firstname.lastname@example.org> To: IETF-Announce <email@example.com> Cc: RFC Editor <firstname.lastname@example.org>, dhc mailing list <email@example.com>, dhc chair <firstname.lastname@example.org> Subject: Protocol Action: 'Active DHCPv4 Lease Query' to Proposed Standard (draft-ietf-dhc-dhcpv4-active-leasequery-07.txt) The IESG has approved the following document: - 'Active DHCPv4 Lease Query' (draft-ietf-dhc-dhcpv4-active-leasequery-07.txt) as Proposed Standard This document is the product of the Dynamic Host Configuration Working Group. The IESG contact persons are Brian Haberman and Terry Manderson. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-dhc-dhcpv4-active-leasequery/
Technical Summary: The Dynamic Host Configuration Protocol for IPv4 (DHCPv4) has been extended with a Leasequery capability that allows a client to request information about DHCPv4 bindings. That mechanism is limited to queries for individual bindings. In some situations individual binding queries may not be efficient, or even possible. In addition, continuous update of an external client with Leasequery data is sometimes desired. This document expands on the DHCPv4 Leasequery protocol, and allows for active transfer of near real-time DHCPv4 address binding information data via TCP. Working Group Summary: Active leasequery for DHCPv4 was initially proposed in 2010, but after 2 revisions it was abandoned due to lack of interest in the WG. In 2013 active leasequery was proposed for DHCPv6 and received strong support in the WG. v6 version was presented in Vancouver (IETF88, Nov 2013) and one of the questions was whether WG is interested in its v4 equivalent. The strong consensus in the room (later confirmed on ML) was to have active leasequery for both DHCPv4 and DHCPv6 and thus the v4 draft was revived. As the principles are the same, this ended up in a somewhat unusually fast path. Cisco seems to have working implementation of this protocol, which is reflected in high maturity of the draft. 00 WG item passed WGLC in March 2014. The -01 (June 2014) addresses all raised comments (all were minor). This work was somewhat stalled as its v6 equivalent required several updates. The latest v6 draft was approved in June 2015 and all the changes required to address IESG comments were applied to v4 (in version -04). Document Quality: This document is of high quality. Personally, I think this is the result of several factors: the imlementation primary author is involved in has this mechanism implemented with actual deployments for serveral years, significant experience of its primary author and also the similarity to its DHCPv6 counter-part, which was recently approved by IESG. Author made extra care to apply all changes to both v4 and v6 drafts. I have reviewed -04 and think it is ready for publication. It is idnits clean. Personnel: Who is the Document Shepherd?
