Tfw u set up Pihole so ur fridge stops spamming you with ads.
I wonder how much longer that will work. DNS over HTTPS is now a thing and totally defeats the mechanism of a pihole.
Maybe block the DoH endpoint and in theory the device might fall back to normal DNS, dunno if that would work.
DoH is tricky to block since it's just using https on port 443. The only options are blocklists of known servers and attempting to detect it with deep packet inspection.
Yeah gotta inspect the traffic and block whatever hostnames it uses.
