Pi-hole DNS Server

Built a network-wide ad and tracker blocker using a Raspberry Pi and custom enclosure — integrated directly into the home network.

Networking Raspberry Pi DNS Linux Security

Overview

In January 2026, I set up a Pi-hole DNS sinkhole on a Raspberry Pi and integrated it into my home network as the primary DNS server. Pi-hole intercepts DNS queries and blocks known ad-serving and tracking domains before they even load.

I also built a custom enclosure for the Pi to keep it clean and protected. The whole thing runs 24/7 and handles DNS for every device on the network — phones, laptops, smart TVs, everything.

How It Works

Raspberry Pi acts as the DNS resolver for the entire home network
Queries for known ad/tracker domains are blocked at the DNS level
Pi-hole dashboard shows real-time stats on blocked queries
Custom blocklists added on top of the defaults
Static IP assigned so the router always routes DNS through it

What I Learned

Linux server setup and SSH administration
Home network configuration (static IPs, router DNS settings)
