Thanks for the reply.
I am convinced that if I am an admin of a BGP router
of our global public Internet, the 2002:... addresses
are reserved for those routers that are authorized
to use the corresponding IPv4 addresses.
Since the ipv4 compatible ipv6 address is deprecated,
I am convinced that 2002:... addresses are the only
"special" addresses for backward compatibility with
IPv4 in today's best practice. Once every router in
the world only runs IPv6, the 2002:... addresses will
be abandoned.
I have never logged on to any BGP router of our
global public Internet. So, no surprise if
I am missing out things.
