Support subdomain

Theoretically, it is feasible to dynamically alter the interaction with the CNAME based on the response to the request.

When a device within a network attempts to connect to, for instance, test.lab.local, and test.lab.local is not present in the cache, a request is sent. Consequently, two potential approaches are possible: either listening on the multicast IP or subscribing to avahi dbus messages (assuming they are available).

Implementing this approach would result in reduced network traffic by minimizing the number of packages transmitted within the network, and it would also introduce additional logic to handle response behavior. An automatic redirection of all *.lab.local requests to lab.local through CNAME during runtime would be achievable through this mechanism.

Avahi don't support query messages in dbus (I couldn't find them)
