Describe the problem

Each request used with Netbird and an output node is very slow on MacOs (can't test on other OS). This seems to be due to time-consuming DNS resolution:

❯ netbird up ; sleep 5 ; httpstat https://console.scaleway.com/

We use an exit node and a DNS configuration at netbird level applied to the group: "All".

@arthur-trt is this still an issue for you with the latest NetBird version?

I see CNAME mentioned in the dig output. In one of the more recent versions we have added support for forwarding CNAME records in addition to A/AAAA so there is chance your issue got fixed in the meantime.
