	Title		: Connecting Mobile IPv6 Nodes Across IPv4 Clouds Back  
                          To IPv6 Domains With Mobile IPv4

This document specifies a mechanism for Mobile IPv6 nodes of IPv6 
Site to continue utilizing Mobile IPv6 services when they roam 
into IPv4 domains. The mechanism is based on Mobile IPv6 and 
Mobile IPv4 glued together by IPv4 encapsulation for delivering 
IPv6 packets between the Mobile IPv6 nodes and their Mobile IPv6 
home agents. To support the mechanism specified in this draft, the 
Mobile IPv6 nodes MUST be Mobile IPv4 capable and MUST NOT utilize 
Mobile IPv6 route optimization when in IPv4 domain, and some of 
the border routers of the site MUST be capable to act as Mobile 
IPv4 home agent(s). The IPv6 site does not need to run 6to4 
protocol, however.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
