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.

This document is a product of the Internet Area Working Group Working Group of the IETF.

This is now a Proposed Standard Protocol.

STANDARDS TRACK: This document specifies an Internet standards track
protocol for the Internet community,and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Internet
Official Protocol Standards (STD 1) for the standardization state and
status of this protocol.  Distribution of this memo is unlimited.
