I was really enthusiastic after reading this blog posting and after some work I had implemented it and it seemed to work very well.
Then came the disappointment that some big firms do sabotage this way of resolving DNS requests.
Unbound does not offer a solution for that and point to Knot to do this. Having two upstream DNS servers next to Pi-hole on the same device is even to me a overkill.
So I want to request a possibility to have a alternative upstream server in Pi-hole.
This alternative upstream server is queried when there is a N/A or time out that can be set by the user starting at two seconds.
As a alternative can be one of the default DNS servers in pihole or added manually.
This is a unusual way of handling a problem but we are confronted by firms that do not like that we have this freedom.
