IPv4 Service Continuity Prefix
Overview
RFC 7335, “IPv4 Service Continuity Prefix”, is a Proposed Standard document published in August 2014 by C. Byrne. It updates RFC 6333. The canonical text is published by the RFC Editor.
Abstract
Dual-Stack Lite (DS-Lite), defined in RFC 6333, directs IANA to reserve 192.0.0.0/29 for the Basic Bridging BroadBand (B4) element. Per this memo, IANA has generalized that reservation to include other cases where a non-routed IPv4 interface must be numbered as part of an IPv6 transition solution.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
