It's designed for low-power embedded devices with network capabilities, such as the Raspberry Pi, but it can also run on any Linux machine. Pi-hole is a network-level advertisement and Internet tracker filtering program for Linux that also functions as a DNS sinkhole and DHCP server for use on a private network. We can also put sites you visit frequently, to a whitelist, which we strongly encourage you to do to help them keep the lights on. That way, when a website (that serves ads) requests its ad servers’ domain to retrieve an ad, Pi-hole checks their domain name with its record of blacklisted ad-services.Īnd then redirect machines to the Raspberry Pi's IP address to begin blocking advertisements right away.

Once installed, you can point your devices to use its IP address such that all traffic on these devices is routed through Pi-Hole. It can be easily installed on Raspberry Pi Zero by executing some installation commands on a Raspberry Pi running Raspberry Pi OS.

Pi-hole is a Raspberry Pi-based network-wide ad filter. But before we proceed, let’s understand what is Pi-hole and how it blocks ads? What is Pi-hole, and What does it do? In this tutorial of Raspberry Pi Zero Series, we will walk you through setting up a Pi-hole on a Raspberry Pi Zero W. Pi-hole can block advertisements on any network device (such as smart appliances), and unlike browser add-ons, it can block adverts on any software. It protects your network from ads and trackers without the need of individual device settings. Pi-hole is a general-purpose network-wide ad-blocker, that can be installed on a Linux-based device to establish a server that filters all of your web traffic at the local network level and block ads on any device connected to your home network. You can either install ad-blocking software on each of your devices or you can use other more efficient methods such as Pi-hole. While online advertising is a major source of money for many of your favorite websites, some people want to avoid it for a variety of reasons, including performance and privacy concerns.
