? Ad-Blocking DNS Server using Raspberry Pi Zero

? Overview

This project uses a Raspberry Pi Zero to create a DNS server that filters out ad-related domains and blocks them before they reach your device. It leverages Pi-hole, a powerful open-source software for network-wide ad blocking.

By routing your device?s DNS queries through the Pi Zero, all ad requests are intercepted and blocked, resulting in a faster and cleaner browsing experience.

?? Components

? Raspberry Pi Zero (W or 2 recommended)
? Micro SD Card (8GB or higher)
? Power Supply (5V, 2A recommended)
? Wi-Fi or Ethernet Connection
?? Any client device (PC, phone, or tablet)

? Working Principle

The Pi-hole software turns your Raspberry Pi Zero into a local DNS server.
All DNS queries from your devices go through the Pi Zero first.
Pi-hole filters the requests and blocks domains known for ads or trackers.
Clean data packets are then sent to your device, keeping browsing fast and ad-free.

? Setup Instructions

Install Raspberry Pi OS on the SD card using Raspberry Pi Imager.
Boot up the Pi and connect it to the internet.

Open the terminal and run:

curl -sSL https://install.pi-hole.net | bash

Follow the on-screen instructions to configure Pi-hole as your DNS server.
Set the Pi-hole?s IP address as the DNS server on your device or router.
Access the web dashboard at:
```
http://<your-pi-ip-address>/admin
```

? Features

Network-wide ad blocking
Easy-to-use web dashboard
Lightweight and runs efficiently on Raspberry Pi Zero
Can be used with multiple devices simultaneously

? How It Works (Simplified)

Your Device ? Raspberry Pi Zero (Pi-hole) ? Internet

The Pi Zero acts as a middleman between your device and the internet.
It filters DNS requests and blocks ad domains before they load.

? Example Use Case

You connect your phone to the same Wi-Fi network as the Raspberry Pi Zero.
When you open a website, instead of loading ads, Pi-hole silently blocks them and only lets the useful content through.

? Future Improvements

Add a custom blacklist/whitelist
Integrate statistics on blocked domains
Use Raspberry Pi Zero 2 for better performance
