The IESG has approved the following document: - 'Softwire Provisioning using DHCPv4 Over DHCPv6' (draft-ietf-dhc-dhcp4o6-saddr-opt-08.txt) as Proposed Standard This document is the product of the Dynamic Host Configuration Working Group. The IESG contact persons are Suresh Krishnan and Terry Manderson. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-dhc-dhcp4o6-saddr-opt/ Technical Summary This document extends DHCPv4 over DHCPv6 (RFC7341) to provide some IPv4-over IPv6 softwire mechanisms and deployment scenarios two additional needed pieces of information. It defines a new DHCPv6 option to indicate the preferred prefix for the client to bind its IPv4 configuration to, and a new DHCPv4 option to indicate the IPv6 address associated with the client's IPv4 configuration, and the procedures to use these options. Working Group Summary This document has been in development, first as an individual submission in the software WG, and more recently in the DHC WG. It has undergone about 10 revisions - with more recent changes being fairly minor. Document Quality The document has had extensive review and input by the working group and by "DHCP experts" and "Softwires experts". Personnel Bernie Volz is the document shepherd. Suresh Krishnan is the current responsible AD.
