The Pihole is a device built on a single board computer (sbc). The device acts as an ad-blocker for your network. There are also blacklists that can be applied or you can build your own.

I good deal for people build these with a raspberry pi, but I found 2 orange pi zeroes for cheap and decided to build on out of this.
Found a video that shows you how to put wireguard vpn and unbound dns on the orange pi along with pihole. Thos is the one I plan on following.
