IPv6 Support Required for All IP-Capable Nodes
RFC 6540, “IPv6 Support Required for All IP-Capable Nodes”, is a Best Current Practice document published in April 2012 by W. George, C. Donley, C. Liljenstolpe, L. Howard. The canonical text is published by the RFC Editor.
Abstract
Given the global lack of available IPv4 space, and limitations in IPv4 extension and transition technologies, this document advises that IPv6 support is no longer considered optional. It also cautions that there are places in existing IETF documents where the term "IP" is used in a way that could be misunderstood by implementers as the term "IP" becomes a generic that can mean IPv4 + IPv6, IPv6-only, or IPv4-only, depending on context and application. This memo documents an Internet Best Current Practice.
What “Best Current Practice” means
Documents the IETF community's recommended operational or procedural practice rather than a protocol specification.
