I'm not making a market statement. I'm looking at a technical scenario, which I laid out in email yesterday. It could be IPv6-only because the network didn't give it an IPv4 address, to pick one possible reason out of a cloud of possible ones. The point is, it *is*, and if the peer it wants to talk with doesn't have a AAAA record, whether native or DNS64, it can't.

So the failure of DNSSEC when DNS64 is used isn't the only issue. Connectivity is also an issue. That's my whole point.
