Does Tailscale use Datadog for telemetry?

Noticed something weird on my pihole/home network setup - I have a fairly fresh WSL2 VM as a testbed for Tailscale and recently set it up to the get DNS from my pihole (on another VM) and saw in pihole logging that the WSL2 computer is trying to resolve “” — there is nothing much running on WSL2 so I am wondering if it is could be something in tailscale doing this?

Tailscale does not use datadog, to my knowledge. I suspect that access is from something else.

ok thanks - let me investigate based on this and isolate somehow.
