the ad blocker your ISP doesn't want you to have

Overview

The video explains how Pi-hole can filter DNS requests across a home network, rather than blocking ads only within a particular browser. Browser extensions such as AdBlock or uBlock must be installed and configured on each browser and device. Pi-hole can filter requests from phones, computers, and smart TVs when their DNS traffic is routed through it.

How Pi-hole Works

Pi-hole acts as a DNS sinkhole. When a device requests a domain, Pi-hole checks it against blocklists. If the domain is listed—for example, as a known advertising, tracking, or malicious domain—Pi-hole blocks the request.

The presenter also describes using Pi-hole to restrict access to selected domains and block known malicious infrastructure, such as command-and-control servers.

Setup Guide

• Hardware: The presenter uses a Raspberry Pi 5, but other Raspberry Pi models or computers can run Pi-hole. The device needs an operating system and a static IP address.
• Docker and Portainer: The demonstration uses Portainer to manage Docker containers. The presenter shows a Pi-hole Docker image and YAML stack, and recommends host networking rather than bridged networking, which caused issues in their setup.
• Configuration: Set a web/API password, deploy the stack and container, then open Pi-hole using the server’s IP address and configured web port. The presenter mentions port 8080, or port 80 if available.
• Dashboard and blocklists: The dashboard displays total DNS queries, blocked queries, the percentage blocked, and the number of domains on the blocklist. The example shown has about 160,000 domains listed.

Network-Wide Filtering

By default, devices must be pointed to Pi-hole manually. To avoid configuring each device, the presenter demonstrates enabling Pi-hole’s DHCP server, disabling DHCP on the router, and entering the router information in Pi-hole.

This process depends on the router and its configuration. Once set up, devices joining the Wi-Fi should be filtered automatically.
