> If I have a million IPv6 servers, can I somehow accomplish the same thing using DNS64/NAT64/464XLAT? Assuming the incoming request is from an IPv4-only host.

You can have a front-end with IPv4 and have a box send the request to the back-end which is IPv6.

This is how FaceMeta works for the last few years: they are completely IPv6 internally in their DC and only have IPv4 at the edges to service 'legacy' connections.

So I still need SNI for IPv4 requests.

Given the finite nature of IPv4 addresses, how can it be otherwise?
