Original Pull Request: https://github.com/netbirdio/netbird/pull/4633

State: open
Merged: No


Describe your changes

Fix bug on Darwin where different instances of netbird clobber each other's DNS entries:
disambiguate 'netbirdDNSStateKeyFormat' by including the interface name.

Related to https://github.com/netbirdio/netbird/issues/446: allows proper DNS resolution when multiple server instances are run on Darwin/MacOS, each instance with its own interface and state.

It is reasonable to assume that multiple instances of netbird server can run on a Darwin machine, as long as they bind to different interfaces and have separate runtime and state directories; in this case each should push its own independent resolver record to the resolver.

This is already the case on Linux, and this bugfix brings feature parity to Darwin.
