Yes but I think OP is referring to plain DNS requests to a preferred server.
You can hijack port 53 and redirect them to your preferred server. Also acts as a method of hardening DNS for devices and apps that do not support encrypted DNS.
Forgot to mention the port but that's it. Notorious devices like smart TVs and consoles like to use the hard coded DNS method
Right, and I am pointing out that non-cooperative devices still won't be blocked by pihole if they so desire.
Only if they do encrypted DNS, and you can still block them, you just can't force them to use the DNS you want. Embedded devices tend to avoid encryption to cut down on hardware requirements, they typically even pull their updates over unencrypted connections. IoT is a crazy world. 😃
And may I point out that if you have embedded devices freely connecting to the Internet you have a lot bigger problems than the fact they use encrypted DNS. Hell you should be so lucky for them to use encrypted DNS, at least it would be secure.
What would be an example of an embedded device?
Media players, TVs, IP cameras, lightbulbs... anything with wifi capability really.
Is there a safe way to use these devices? I’m moderately tech savvy at best, and I do worry a lot about my tv. I also use some smart plugs to manage equipment on my aquarium, but that’s it. I’ve considered the implications of these devices, but didn’t know if there was anything I could do about it.
