Â - Technical Summary Â (Abstract from "Detection of Network Attachment (DNA) in IPv4") Â The time required to detect movement (or lack of movement) between Â subnets, and to obtain (or continue to use) a valid IPv4 address may Â be significant as a fraction of the total delay in moving between Â points of attachment.Â This document synthesizes experience garnered Â over the years in the deployment of hosts supporting ARP, DHCP and Â IPv4 Link-Local addresses.Â A procedure is specified for detection of Â network attachment in order to better accommodate mobile hosts. Â The document addresses a need for compilation of experiences with Â various protocol specifications and formal description of protocol Â operation based on those experiences.Â Members of the dhc WG Â provided significant expert input based on experience with DHCP Â client/server deployment and operation. Â - Working Group Summary Â The dhc WG was actively involved in the development of this Â document and provided significant input.Â The consensus of the WG Â is to submit the document for publication.Â The issues raised Â during discussion of this document, including the WG last call, are Â listed at http://www.drizzle.com/~aboba/DNA/ Â - Protocol Quality Â This document does not define a protocol; rather, it provides a Â formal description of procedures for host movement that are useful Â in protocols like DHCP and IPv4 link-local addresses.Â The quality Â of the document is excellent. This document was reviewed for the IESG by Margaret Wasserman.
