Technical Summary

   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.

Working Group Summary

   Although the reference 464XLAT architecture was published as Informational, the
   document specifies normative behavior for CLAT nodes for deterministic,
   consistent, and interoperable implementations.

   The updates to RFC 8585 are included in this document rather than offloading
   them to a separate document to help implementers/operators easily find latest
   CLAT node clarifications in a self-contained document.

Document Quality

   This document provides updates based upon CLAT deployment and implementation
   experiences.

Personnel

   The Document Shepherd for this document is Michael Richardson.
   The Responsible Area Director is Mohamed Boucadair.
