IoT devices are starting to use hardcoded DNS servers instead of using the one provided by DHCP, which negates the benefits of Pi-Hole on those devices.
For now, I've configured my router to force all UDP port 53 traffic to my Pi-Hole which overrides what I mentioned above.
But, in the future we may start to see IoT Devices hard-code DoH servers which will be harder to force over to the Pi-Hole.
Your computer sends the raw domain name to pi-hole (e.g. ads.google.com), and pi-hole returns 0.0.0.0 if it's on the block list.
There's nothing Google or anyone can do to make pi-hole stop working.
