Mobile IPv4 is a standard mobility protocol that enables IPv4 device
   to move among networks while maintaining its IP address.  The mobile
   device has the Mobile IPv4 client function to signal its location to
   the routing anchor, known as the Home Agent.  However, there are many
   IPv4 devices without such capability due to various reasons.  This
   document describes Proxy Mobile IPv4 (PMIPv4), a scheme based on
   having the Mobile IPv4 client function in a network element to
   provide mobility support for an unaltered and mobility-unaware IPv4
   device, and the existing application of PMIPv4 in WiMAX Forum and
   3GPP2.

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.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
