GT> I am confused about this one. MIP6 RO requires the CN to
participate in MIP6 signaling for the Return Routability tests. How
would an IPv4 only node participate in such an IPv6 specific
signaling?. This makes no sense to me.
I was also thinking if any other MIP related scenario is worth
considering here, e.g., MIP HA inside vs outside the NAT64. MIPv4 and
MIPv6 protocols, however, are entirely incompatible so MIPv4 to MIPv6
translation is not a realistic option as far as I can tell. My
inclination is to just forget about Mobile IP and all its versions and
denominations for now.
