(Tailscale cofounder) That’s a good callout on DoH support, thanks.

That said, note that if you run your own DNS server on your tailnet, the regular UDP DNS is automatically private because it’s carried over Tailscale. That’s the most common setup for non-SaaS DNS servers. DoH doesn’t really add anything in that arrangement. (And it’s more fiddly because you need to get and refresh a TLS cert.)
