- 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.
