Hi all, We've updated a new version of draft-ietf-dhc-dhcpv6-prefix-length-hint-issue (version 06) according to the comments received during IESG Last Call. Main changes include: 1. Changed text at the end of the first and second paragraph of the “Solution” part of section 3.2. OLD: If the server does not have a prefix with length matching the prefix-length hint value, then the server SHOULD provide the prefix with the shortest length possible which is closest to the prefix-length hint value. NEW: If the server does not have a prefix with length matching the prefix-length hint value, then the server SHOULD provide the prefix whose length is shorter and closest to the prefix-length hint value. 2. Added text at the last paragraph of the “Solution” part of section 3.2, to describe what the server should do if it cannot provide any prefixes to the client. 3. Changed option 4 of the “Solution” part of section 3.5: OLD: Assign the original delegated prefix with 0 preferred-lifetime, a short non-zero valid-lifetime... NEW: Assign the original delegated prefix with 0 preferred-lifetime, a specific non-zero valid-lifetime depending on actual requirement... 4. Added reference to RFC3315 in section 4 for security considerations in DHCP 5. Added a sentence at the end of section 3.1 to explain that there is no requirement for the order of the two IAPREFIX options. 6. Expanded the words “IAID” and “IA_PD” on first use in the second paragraph of the “Problem” part of section 3.1: IAID (Identity Association IDentifier) IA_PD (Identity Association for Prefix Delegation) 7. Throughout the draft, changed “the prefix which length is” to “the prefix whose length is”. Thank you, Tianxiang ---------- Forwarded message ---------- From: <internet-drafts@ietf.org> Date: 2017-04-01 14:10 GMT+08:00 Subject: New Version Notification for draft-ietf-dhc-dhcpv6-prefix-length-hint-issue-06.txt To: Cong Liu <gnocuil@gmail.com>, Yong Cui <yong@csnet1.cs.tsinghua.edu.cn>, Tianxiang Li <peter416733@gmail.com> A new version of I-D, draft-ietf-dhc-dhcpv6-prefix-length-hint-issue-06.txt has been successfully submitted by Tianxiang Li and posted to the IETF repository. Name: draft-ietf-dhc-dhcpv6-prefix-length-hint-issue Revision: 06 Title: DHCPv6 Prefix Length Hint Issues Document date: 2017-03-31 Group: dhc Pages: 9 URL: https://www.ietf.org/internet-drafts/draft-ietf-dhc-dhcpv6- prefix-length-hint-issue-06.txt Status: https://datatracker.ietf.org/doc/draft-ietf-dhc-dhcpv6- prefix-length-hint-issue/ Htmlized: https://tools.ietf.org/html/draft-ietf-dhc-dhcpv6-prefix- length-hint-issue-06 Htmlized: https://datatracker.ietf.org/doc/html/draft-ietf-dhc- dhcpv6-prefix-length-hint-issue-06 Diff: https://www.ietf.org/rfcdiff?url2=draft-ietf-dhc-dhcpv6- prefix-length-hint-issue-06 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. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org. The IETF Secretariat
