Pi-hole-Home-DNS

In this project, I will show you how to assemble a Raspberry Pi that filters out unwanted ads through a DNS sinkhole on your router.

What is a Pi-hole?

A Pi-hole is a Raspberry Pi configured with a DNS sinkhole that protects devices on your network from unwanted content.

Here is a link to the documentation : https://docs.pi-hole.net

Raspberry Pi

In terms of price, the Pi Zero is the best bang for your buck as this server runs headless, so a better Raspberry Pi is optional. However, within this guide, I have used a Pi 3 B. I have had a great experience using the Raspberry Pi 3 B for other projects, so I recommend it.

Raspberry Pi Case

I recommend this iUniker Raspberry Pi 3 b+ case. It comes with a fan, heatsink pads, and a power supply.

Getting Started

Install the Headless Firmware onto your Raspberry Pi

Please do this by first installing the Raspberry Pi Imager on their website: https://www.raspberrypi.com/software/

After installing the imager, select the device you want to connect and your storage device, then install the lite version of the Raspi OS.

Installing Pi-hole

First, update your raspberry Pi with,

sudo apt-get update && apt-get upgrade

Then, input the following command to install Pi hole :

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

Next, You will have to complete the installation wizard that displays the required IP Addresses and Passwords to be able to access your Pihole remotely.

I recommend going with Cloudflare as a DNS provider and also make sure to allow the Pi-Hole to rely on third party lists to block ads!

Now you can access your Pi-Hole Web Interface through your RaspberryPi's IP!

Here is what my Admin panel looks like, although you might be asking. Why is it so empty? It's because you must add your Pi-Hole as the default DNS route.

Next, Here is how you add your Pihole as your preferred DNS server

Step 1.) Go to your adapter options through your network status panel

Step 2.) Go to your properties of your main wifi-adapter

Step 3.) Double click on your IPv4

Step 4.) Add your Pi-Hole's IP address as your preffered DNS server and press OK

Congrats! Have fun blocking ADs on your devices through a DNS Sinkhole!
