I could be wrong here, but the DNS servers used by Netbird would only be used for domain names registered to Netbird, not for generic internet browsing or the like, unless you've setup a matching domain as ALL.

This is a generic DNS server matching all requests.

Are you setup to use netbird as an exit node then, with it having highest priority in routes?

This should'nt be relevant for DNS, but yes, I also use a Netbird host as exit node.
