The IESG has received a request from the Dynamic Host Configuration WG (dhc) to consider the following document: - 'Softwire Provisioning using DHCPv4 Over DHCPv6' <draft-ietf-dhc-dhcp4o6-saddr-opt-04.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2018-09-07. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract DHCPv4 over DHCPv6 (RFC7341) is a mechanism for dynamically configuring IPv4 over an IPv6-only network. For DHCPv4 over DHCPv6 to function with some IPv4-over-IPv6 softwire mechanisms and deployment scenarios, the operator needs to know the IPv6 address that the client will use as the source of IPv4-in-IPv6 softwire tunnel. This address, in conjunction with the client's IPv4 address, and (in some deployments) the Port Set ID are used to create a binding table entry in the operator's softwire tunnel concentrator. This memo defines a DHCPv6 option to convey IPv6 parameters for establishing the softwire tunnel and a DHCPv4 option (to be used only with DHCP 4o6) to communicate the source tunnel IPv6 address between the DHCP 4o6 client and server. It is designed to work in conjunction with the IPv4 address allocation process. This document updates "DHCPv6 Options for Configuration of Softwire Address and Port-Mapped Clients" (RFC7598), allowing OPTION_S46_BR (90) to be enumerated in the DHCPv6 client's ORO request and appear directly within subsequent messages sent by the DHCPv6 server. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-dhc-dhcp4o6-saddr-opt/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-dhc-dhcp4o6-saddr-opt/ballot/ No IPR declarations have been submitted directly on this I-D.
