I put this in Off Topic as it’s more of just a question. Given that DoH will query a server for DNS details via HTTPS does that mean the original DNS request for that server would go via the usual DNS route?
So if I am using dns.google.com/experimental as my DoH server I would see only DNS requests for dns.google.com any longer in Pi Hole. If so would blocking dns.google.com at the Pi Hole level block access to this DoH server?
I am wondering how to get around this DoH issue whereby applications or devices will be free to query their own DNS server of choise and not that of the OS or network. My options are either to block those servers on Pi Hole or to drop packets destined for the ip addresses at the router. Either way I do not want to go back to a time where I have minimal control over the data leaving my network.
