I donâ??t believe there is a reason that folks should accept this prefix from a transit/peer.  If they have need for 6to4 within their network, they should operate their own local 6to4 relays.

It seems native IPv6 is fairly widely available:


And there is almost zero 6to4 activity in those stats as well.  Since itâ??s a known path for abuse as well, I would expect networks to not carry these IPv6 routes and filter them.
