The IESG has received a request from the IPv6 Operations WG (v6ops) to
consider the following document: - '464XLAT Customer-side Translator (CLAT):
Node Behavior and
   Recommendations'
  <draft-ietf-v6ops-claton-12.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
last-call@ietf.org mailing lists by 2025-11-21. Exceptionally, comments may
be sent to iesg@ietf.org instead. In either case, please retain the beginning

Abstract


   464XLAT defines an architecture for providing IPv4 connectivity
   across an IPv6-only network.  The solution involves two functional
   elements: provider-side translator (PLAT) and customer-side
   translator (CLAT).  This document updates the 464XLAT specification
   (RFC6877) and Requirements for IPv6 Customer Edge Routers (RFC8585)
   by further defining CLAT node behavior and IPv6 Customer Edge Routers
   to Support IPv4-as-a-Service by providing recommendations for the
   node developers on enabling and disabling CLAT.
