 To minimize system changes, NetBird runs a local embedded DNS resolver on each peer.
 This resolver handles queries for domain names of registered peers in your network and forwards queries to upstream nameservers that you configure in the system.

 ### Nameserver
 A nameserver is an upstream DNS server responsible for name resolution. If a query is not related to a peer domain name,
 it will be resolved by one of the upstream servers. You can assign private and public IPs, as well as custom ports for your nameservers.

 ### Metric and priority
 Metric defines prioritization when choosing the main routing peer in a high availability network. Lower metrics have higher priority.
 Outside of high availability routes, the metric has no effect.
