Describe the problem

basically the domain-based Network Resource:

properly registers in a routing table after it gets resolved by the DNS, but it does not get to this due to point 2
nothing is registering the domain with system's resolver so it cannot get to point 1) without additional help (point 3)
a workaround is to create a dummy Nameserver in the management for the domain

the only reason it works on Linux clients is due to how resolved behaves with +DefaultRoute, normally it should not work here either

I am pretty sure this should be implemented/fixed

To Reproduce

create a Network with a domain Resource
the selected domain does not get registered with operating system's resolver

Expected behavior

the domain defined in a Network Resource is poperly registered with operating system's DNS resolver

Are you using NetBird Cloud?
