The IESG has received a request from the Dynamic Host Configuration WG (dhc) to consider the following document: - 'DHCPv6 Prefix Length Hint Issues' <draft-ietf-dhc-dhcpv6-prefix-length-hint-issue-05.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 2017-02-09. 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 DHCPv6 Prefix Delegation (RFC3633) allows a client to include a prefix-length hint value in the IA_PD option to indicate a preference for the size of the prefix to be delegated, but is unclear about how the client and server should act in different situations involving the prefix-length hint. This document provides a summary of the existing problems with the prefix-length hint and guidance on what the client and server could do in different situations. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-dhc-dhcpv6-prefix-length-hint-issue/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-dhc-dhcpv6-prefix-length-hint-issue/ballot/ No IPR declarations have been submitted directly on this I-D.
