IPv4 Support for Proxy Mobile IPv6
Abstract
This document specifies extensions to the Proxy Mobile IPv6 protocol
for adding IPv4 protocol support. The scope of IPv4 protocol support
is two-fold: 1) enable IPv4 home address mobility support to the
mobile node, and 2) allow the mobility entities in the Proxy Mobile
IPv6 domain to exchange signaling messages over an IPv4 transport
network.
