Can you paste the output of `scutil --dns` ?

On a Windows 10 system running Tailscale 1.28 when I ping a single-label MagicDNS name, in Wireshark on the Tailscale interface I see: - regular DNS requests, which receive responses...

There are registry keys to disable mDNS globally: https://f20.be/blog/mdns So far I haven't found a setting to disable it for a specific interface. PPP interfaces have a `connection.mdns` setting, but...

Disappointingly, we already set a registry key to disable multicast on the Tailscale interface but the mDNS frames are sent regardless.

Split DNS does work for some people, I'm using it on an Android 12 device for example. Around the time of the bugreport we see DNS packets being sent to...
