We have a design that scales well. It's called DNSSEC.
ISC has worked on DNSSEC development for well over 10 years.
Once development stopped we looked at methods to speed up
it deployment. It works today. People were deploying it
well before this recent problem started.

The problem is that is will take time to get people to sign
their zones.

DNSSEC security is end to end. Publisher to validator. You
don't need to secure individual links which is what the
random query ports attempt to do. Put the validator on
the same machine as the application and you are only worried
about securing interprocess communication which unless the
attacker is on the machine should be secure.
