It goes to the USA and back again. They would need NAT64 servers in every
region and then let the DNS64 service decide which one is close to you by
encoding the region information in the returned IPv6 address. Such as
An anycast solution would need a distributed NAT64 implementation, such
that the NAT64 servers could somehow synchronize state. A more simple
solution is just to have the DNS64 be anycast and have a DNS64 at each
NAT64 location with the DNS64 returning pointers to the local NAT64.
Now, can we have a public MAP server? That might scale. The geo blockers
will hate it. What is not to like?
