Pi-hole What is it? It’s a DNS level adblocker, this means running this on your network and setting Pi-hole as your DNS it will filter out ads for your whole network. It’s easy to set up using a Raspberry Pi for example, all you need is a Pi and an SD card. You should use BalenaEtcher to flash the OS, I recommend Raspberry Pi OS on a Pi for stability. But you can use any Linux based OS that utilizes systemd or sysvinit.
