Technical Summary
The current Mobile IPv6 and NEMO specifications support IPv6 only.
This specification extends those standards to allow the registration
of IPv4 addresses and prefixes, respectively, and the transport of
both IPv4 and IPv6 packets over the tunnel to the home agent. This
specification also allows the Mobile Node to roam over both IPv6 and
IPv4, including the case where Network Address Translation is present
on the path between the mobile node and its home agent.

RFC Editor Note
Please add the following paragraph to the end of Section 5.4.4:
This specification does not support mobile nodes returning home
while using IPv4. That is, the IPv4 support is only defined for
mobile nodes that are in a visited network.
