Description

It is possible to return multiple NAT64 prefixes - ie multiple AAAA records returned pointing to each prefix. The servers listed at the top of https://nat64.xyz do this for example.

The purpose of such a setup is to allow load balancing and failover, allowing the use of multiple NAT64 gateways at once.

It sounds like this would need to be implemented upstream in Unbound. The DNS64 module doesn't currently support doing so:
