I have looked carefully at all corrections (thanks for referencing diff). Support publication again. Even more: both my comments were addressed. I have a small concern that corrections have a form of “discussion” that is not appropriate for RFC. I hope IETF editors will correct this. RFC should not “make excuses” before demanding something. It undermines any SHOULD or MAY. Extreme politeness may be good for WGLC but not for RFC. SHOULD should be SHOULD without any excuses. Ed/ From: ipv6 <ipv6-bounces@ietf.org> On Behalf Of Bob Hinden Sent: Wednesday, April 10, 2024 18:29 To: IPv6 List <ipv6@ietf.org> Cc: Bob Hinden <bob.hinden@gmail.com> Subject: [IPv6] Second Working Group Last Call for <draft-ietf-6man-rfc6724-update> Given the number of changes since the first w.g. last call, the chairs, in consultation with the authors, are staring a second 6MAN working group last call for this document. This email starts a second two week 6MAN Working Group Last Call on advancing "Preference for IPv6 ULAs over IPv4 addresses in RFC6724" document https://datatracker.ietf.org/doc/draft-ietf-6man-rfc6724-update/ as a Standards Track document. A summary of changes since the -06 version is below. A good diff to review is: https://author-tools.ietf.org/iddiff?url1=draft-ietf-6man-rfc6724-update-08&url2=draft-ietf-6man-rfc6724-update-06&difftype=--html [New draft on left due to line length problem with old draft] Substantive comments and statements of support for publishing this document should be directed to the ipv6@ietf.org<mailto:ipv6@ietf.org> mailing list. Editorial suggestions can be sent to the authors. This last call will end on 24 April 2024 23:59 UTC. Also, one issue the authors would like feedback on is if the requirement is a SHOULD or MUST for inserting known-local ULA prefixes into their policy table with a precedence above both GUAs and IPv4, while leaving all other general ULAs at a lower precedence. It is a SHOULD in the -08 draft, but there has been support for a MUST in the discussion.

Section 4: Changes the 6to4 prefix deprecation to match Teredo, adds further clarity and reference to RFC6724 section 10.7 Section 5: Add text to upgrade the requirement to automatically insert known-local ULAs into a node's policy table from a MAY to a SHOULD. Section 5.3 Further define insertion and removal parameters and requirements for known-local ULA prefixes into table and associated values and label Section 7.2: Further clarify GUA-GUA preferred over ULA-ULA details Section 7.3: Further clarify ULA-ULA preferred over IPv4-IPv4 details Section 8: Housekeeping and formatting changes Section 9.2: Describe the new known-local interaction and how it addresses issues with ULAs in global DNS Further copy edit and housekeeping.
