The overview

What Pi-hole is for

Once deployed on a dedicated device (e.g., Raspberry Pi, VM, or Docker container), Pi-hole provides a web-based administrative interface accessible via a browser. This interface allows operators to configure DNS filtering rules, monitor real-time query logs, and manage blocklists for all devices on their local network, effectively acting as a DNS sinkhole to prevent ad and tracker domains from resolving.

Quick answers

Frequently asked questions

1What hardware is required to run Pi-hole?⌄

Pi-hole is designed to run on low-power devices like a Raspberry Pi (any model from Zero W upwards), a virtual machine (VM) on a hypervisor like Proxmox or ESXi, or a Docker container on an existing server. It requires a Linux-based OS and minimal RAM/storage.

2How does Pi-hole handle encrypted DNS (DoH/DoT)?⌄

Pi-hole itself operates as a traditional DNS resolver. To utilize DoH/DoT, you'd typically configure a local DNS proxy like `unbound` or `cloudflared` on the same host, which then forwards encrypted queries to an upstream DoH/DoT provider, with Pi-hole acting as the frontend for filtering.

3Can Pi-hole block ads on YouTube or other streaming services?⌄

Pi-hole primarily blocks ads by preventing DNS resolution of known ad domains. While effective for many in-browser ads, it generally cannot block ads embedded directly within video streams (like YouTube or Hulu) that are served from the same domain as the content itself, as this would also block the content.

4Is there a subscription fee for Pi-hole?⌄

No, Pi-hole is open-source software and is completely free to download and use. The only costs involved are for the hardware you choose to run it on (e.g., a Raspberry Pi) and your internet connection.

5How do I update Pi-hole and its blocklists?⌄

Updates for the Pi-hole software itself are performed via the command line on the host system using `pihole -up`. Blocklists are updated through the web admin interface under 'Tools' -> 'Update Gravity', or via the command line with `pihole -g`.
