    How do you block the DoH servers in the pihole? Pihole is a DNS server, devices using a third party DoH server would just bypass the pihole as they’re using the IP of the DoH with no DNS lookup required. No?

    To block DoH I think you need to block it at the firewall level with a list of blocked IPs for the DoH servers you want to block over 443

      You’re probably better off blocking it at the firewall level. It would be more thorough but also more effort. In my experience, most devices/apps that use DoH call a domain name rather than an IP. If you block the domain in piHole, the app cant resolve the DoH server IP and therefore won’t be able to use DoH.
