100001 464XLAT defines an architecture for providing IPv4 connectivity across an IPv6-only network. The solution involves two functional elements: a provider-side translator (PLAT) and a 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 node developers on enabling and disabling CLAT. /api/v1/person/person/112869/2026-09-06T20:54:51Z/api/v1/group/group/1578/136959/api/v1/name/intendedstdlevelname/ps/[]draft-ietf-v6ops-clatonmcr@sandelman.ca25/api/v1/doc/document/draft-ietf-v6ops-claton/16/api/v1/person/email/mcr@sandelman.ca//api/v1/doc/state/1//api/v1/doc/state/110//api/v1/doc/state/115//api/v1/doc/state/17//api/v1/doc/state/216//api/v1/doc/state/44//api/v1/name/streamname/ietf//api/v1/submit/submission/144222//api/v1/submit/submission/150553//api/v1/submit/submission/146297//api/v1/submit/submission/147073//api/v1/submit/submission/149459//api/v1/submit/submission/153505//api/v1/submit/submission/154321//api/v1/submit/submission/154814//api/v1/submit/submission/155378//api/v1/submit/submission/155798//api/v1/submit/submission/156402//api/v1/submit/submission/157308//api/v1/submit/submission/157385//api/v1/submit/submission/157753//api/v1/submit/submission/158213//api/v1/submit/submission/160410//api/v1/submit/submission/160914/464XLAT Customer-side Translator (CLAT): Node Behavior and Recommendations/api/v1/name/doctypename/draft/
