Hi chairs,

Please hold the WGLC, we still have some further changes to make as a result of the 6man WG discussion in Prague.

These include updating the abstract, the addition of text clarifying how the change will affect behaviour more clearly (Jen’s point), simplification of sections 3 and 6, and reduction and possible removal of Section 7.

There’s also a potential change of title given the re-instantiation of the 5.5 text.

Thanks,
Tim

Chairs,

We have updated our draft to reflect feedback from the list as well as from IETF 118 and respectfully request consideration for WGLC. We believe this addresses the input and the problems it is aimed at remedying.

Thanks,

Nick, Jeremy, Tim

Internet-Draft draft-ietf-6man-rfc6724-update-04.txt is now available. It is a
work item of the IPv6 Maintenance (6MAN) WG of the IETF.

   Title:   Preference for IPv6 ULAs over IPv4 addresses in RFC6724
   Authors: Nick Buraglio
            Tim Chown
            Jeremy Duncan
   Name:    draft-ietf-6man-rfc6724-update-04.txt
   Pages:   11
   Dates:   2023-11-21

Abstract:

   This document updates [RFC6724] based on operational experience
   gained since its publication over ten years ago.  In particular it
   updates the precedence of Unique Local Addresses (ULAs) in the
   default address selection policy table, which as originally defined
   by [RFC6724] has lower precedence than legacy IPv4 addressing.  The
   update places both IPv6 Global Unicast Addresses (GUAs) and ULAs
   ahead of all IPv4 addresses on the policy table to better suit
   operational deployment and management of ULAs in production.  In
   updating the [RFC6724] default policy table, this document also
   demotes the preference for 6to4 addresses.  These changes to default
   behavior improve supportability of common use cases such as, but not
   limited to, automatic / unmanaged scenarios.  It is recognized that
   some less common deployment scenarios may require explicit
   configuration or custom changes to achieve desired operational
   parameters.
