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

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 mailing lists by 2017-02-09. Exceptionally, comments may be
sent to instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.


   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.
