Nick, the solution to this is to do DNS64 in the validator. If the
validator is a stub resolver, do the DNS64 hack there. AFAIK the
technology to support this already exists.
DNS64 really should just be made historic. It does not work with
DNSSEC. There has NEVER been a NEED for NAT64 or DNS64. They
provides NO BENEFIT over other methods. Every proported benefit
turns out not to exist.
Go do the comparitive analysis.
I respectfully disagree. dual-stack incur many additional costs
operationally. deploying v6only infrastructure is more cost effective,
specially over the long run. nowadays, statistics show that a large
amount of trafic could be carried over IPv6, which means then that you
« just » need to care about the tail of the IPv4-only destinations,
which is where nat64/dns64 comes. But I guess you know all this.

DNSSEC and DNS64 do not get along. DNSSEC for “A records only”
is
broken.
Is this the reason why all content must go v6?
Or is the case for DNSSEC still questionable?
Or do end hosts need to perform DNS64 so “DNSSEC for A records
only”
can be intact?
