This document specifies IPv4 compatibility mechanisms that can be
implemented by IPv6 hosts and routers.  These mechanisms include
providing complete implementations of both versions of the Internet
Protocol (IPv4 and IPv6), and tunneling IPv6 packets over IPv4 routing
infrastructures.  They are designed to allow IPv6 nodes to maintain
complete compatibility with IPv4, which should greatly simplify the
deployment of IPv6 in the Internet, and facilitate the eventual
transition of the entire Internet to IPv6.  This RFC is the product of
the New Generation Transition Working Group of the IETF.

This is now a Proposed Standard Protocol.

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. 

This announcement is sent to the IETF list and the RFC-DIST list.
