It should be noted in-network DNS64 is a fallback for situations where end devices don't have native support for NAT64 (either with a CLAT or with local DNS64). (Network side DNS64 breaks DNSsec)

RedHat is working to get CLAT on regular Linux hosts, where it has been direly missing.

I guess this is because sometimes hosts use bare IPv4 address and don't go through DNS and thus DNS64 doesn't work for them? And if the host supports translating the addresses itself (CLAT) why use DNS64 at all?

But this is the first time I've heard of that. Do any devices support it at all? I'm still struggling with IPv6 issues on my iphone.

Desktop Linux is to my knowledge the only "major" OS without a CLAT; Android and iOS/MacOS have had a CLAT for ages and I believe Windows got one recently*.

* not sure about that

This, and also legacy applications just not using IPv6 sockets.
