The IESG has approved the following document: - 'Detecting Network Attachment in IPv4 (DNAv4) ' <draft-ietf-dhc-dna-ipv4-18.txt> as a Proposed Standard This document is the product of the Dynamic Host Configuration Working Group. The IESG contact persons are Margaret Wasserman and Mark Townsley. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-dhc-dna-ipv4-18.txt  - Technical Summary  (Abstract from "Detection of Network Attachment (DNA) in IPv4")  The time required to detect movement (or lack of movement) between  subnets, and to obtain (or continue to use) a valid IPv4 address may  be significant as a fraction of the total delay in moving between  points of attachment. This document synthesizes experience garnered  over the years in the deployment of hosts supporting ARP, DHCP and  IPv4 Link-Local addresses. A procedure is specified for detection of  network attachment in order to better accommodate mobile hosts.  The document addresses a need for compilation of experiences with  various protocol specifications and formal description of protocol  operation based on those experiences. Members of the dhc WG  provided significant expert input based on experience with DHCP  client/server deployment and operation.  - Working Group Summary  The dhc WG was actively involved in the development of this  document and provided significant input. The consensus of the WG  is to submit the document for publication. The issues raised  during discussion of this document, including the WG last call, are  listed at http://www.drizzle.com/~aboba/DNA/  - Protocol Quality  This document does not define a protocol; rather, it provides a  formal description of procedures for host movement that are useful  in protocols like DHCP and IPv4 link-local addresses. The quality  of the document is excellent. This document was reviewed for the IESG by Margaret Wasserman. _______________________________________________ IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
