RFC 3056
Connection of IPv6 Domains via IPv4 Clouds
February 2001
   In any case, any 6to4 traffic whose source or destination address
   embeds a V4ADDR which is not in the format of a global unicast
   address MUST be silently discarded by both encapsulators and
   decapsulators.  Specifically, this means that IPv4 addresses defined
   in [RFC 1918], broadcast, subnet broadcast, multicast and loopback
   addresses are unacceptable.
