[FEATURE]: Automatic dns fallback #33
Description
🚀 Feature Description
Automatic dns fallback
💭 Problem/Motivation
If a public dns over https (DoH) fails to get the domain/s (e.g. NXDOMAIN) or doesn't send a response in a time limit (e.g. 5 sec) it switches (back) to None (device/network default dns provider).
It could be usefult to provide a better and smoother experience and help troubleshoot some problems by excluding the dns query ones.
💡 Proposed Solution
Add a check on dns response, if the status is NXDOMAIN or the dns packet containing the response is not received before a timeout (e.g. 5 sec) the DoH switches back to None.
