Can XBox Networking on Windows 10 use Native IPV6?

Basically, the question is as the title says. I’ve been playing Forza Horizon 4 a lot since it’s on Gamepass, but the networking reliability has been absolutely horrible. I’ve tried all sorts of things, from ensuring all ports are forwarded correctly to using a different Teredo server. In the end I switched my router for another one I had lying around, and joined my ISP’s ipv6 beta program, and got a proper ipv6 connection working. Then to my dismay I found that Teredo was still being enabled and used by Xbox networking, along with the consistent disconnects and other difficulties.

So, the question is not about how I fix Teredo, but simply, does Xbox Networking on Windows have support for native ipv6? It feels as though that should be a more robust solution that relying on what amounts to a proxy server that’s nowhere near my machine.
