Pi-hole

The Pi-hole® is a DNS sinkhole that protects your devices from unwanted content without installing any client-side software.

The smallest device I have known that can run a pihole is a raspberry pi zero. But I feel it is possible have a device so small, it can be powered from the same Ethernet cable that connects to the router and still be a DNS sinkhole.

Any ideas or suggestions for experimentation?

I had two pi zeros running different instances of pihole when I started using pihole, one was my primary DNS and one was my secondary DNS. It was probably over kill to have 2 but being able to have a backup made me feel good.

As I got more into doing more with my pi I have two pi 5’s that back up to a nextcloud host I have outside of my LAN, 1 has a TB NVME drive and one has a 500 GB NVME drive but they are definitely over kill for just pihole.
