What’s the Function of a Pi-hole in Your Network Defence (And Why You Should Totally Use It with PiVPN)


The Digital Adpocalypse Is Real—So Is Pi-hole

You ever feel like your devices are snitching on you 24/7? Ads follow you around like that one ex who just won’t take a hint. From your smart fridge to your phone, everything’s leaking data and calling home—even when you’re just watching cat videos.

That’s where Pi-hole comes in like the digital Gandalf: “You shall not pass… any DNS requests to shady ad servers!”

Pi-hole is a DNS sinkhole for your entire network. It acts as your first line of defence against annoying ads, trackers, telemetry, and sometimes even malware domains. You can run it on a Raspberry Pi, pair it with PiVPN, and suddenly you’ve built your own mini fortress of solitude (minus the ice).


So, What Exactly Does Pi-hole Do?

Let’s break it down:

Pi-hole = Network-wide Ad Blocker

Unlike browser extensions, Pi-hole works at the network level. That means it:

  • Blocks ads in apps, games, and smart TVs
  • Stops sneaky trackers before they even load
  • Reduces bandwidth usage (less junk = faster speed)
  • Works for every device, even IoT weirdos

TL;DR? If it tries to phone home through DNS and it’s on the blocklist—boom, denied.

It Replaces Your DNS Resolver

Pi-hole becomes your local DNS server. So instead of asking Google or Cloudflare to resolve “clickbaitcentral.com,” your devices ask Pi-hole. And if that domain is on your blocklist? Pi-hole replies with a polite “nah.”

Think of it as firewall-lite meets adblock on steroids.


My Setup: Pi-hole + PiVPN = Home Network Ninja Mode

Here’s what I run at home:

  • Raspberry Pi 4 with 8GB RAM
  • Pi-hole + PiVPN (WireGuard)
  • Static IP and Dynamic DNS with DuckDNS
  • Firewall rules on UFW

When I’m out and about, I just connect to my VPN, and voilà—all my mobile traffic routes through Pi-hole. I get ad-free browsing even on public Wi-Fi, with better privacy and zero creepy targeted ads.

Bonus: My battery lasts longer since fewer ad scripts load. 🙌


Why You Should Use Pi-hole with PiVPN

1. Take Back Control from Advertisers

Do you really want Meta, Google, and Amazon to track every digital sneeze you make? Didn’t think so.

Pi-hole blocks:

  • Google Ads
  • Facebook trackers
  • App telemetry
  • Malware domains

You can use curated blocklists from places like Firebog.net, or custom ones to block specific garbage (I’m looking at you, TikTok’s background data syncing).

2. Enforce DNS Filtering Remotely

With PiVPN, you can connect to your home network from anywhere. That means:

  • Your phone always uses your Pi-hole’s DNS
  • You bypass dodgy DNS servers at cafés, airports, hotels
  • Kids or employees on the go still get filtered internet

This combo is perfect for families, small businesses, or paranoid geeks (ahem, hi).

3. Improves Performance and Privacy at the Same Time

By cutting out ad domains, your pages load faster. Less DNS resolution = less wait time. And since your DNS stays encrypted via WireGuard, ISPs can’t snoop on your browsing habits.

It’s like going incognito… for real.


Installation Basics (Don’t Panic, It’s Easy)

Step 1: Install Pi-hole

SSH into your Raspberry Pi and run:

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

Follow the prompts. Set a static IP. Choose your upstream DNS provider (Cloudflare, Google, etc.).

Step 2: Install PiVPN (If You Haven’t Yet)

curl -L https://install.pivpn.io | bash

Choose WireGuard for speed and security. After setup, generate your .conf file with:

pivpn add

Step 3: Route Your VPN DNS to Pi-hole

Open your Pi-hole admin dashboard (usually at http://pi.hole), then:

  • Go to Settings → DNS
  • Set your VPN client’s DNS IP to your Pi-hole IP (e.g., 192.168.1.2)

Then on your .conf file, edit:

DNS = 192.168.1.2

Now all VPN clients will use Pi-hole to resolve DNS. Clean and beautiful.


Real Commands I Use for Monitoring

View Top Blocked Domains:

pihole -t

Update Gravity Blocklist:

pihole -g

Check Service Status:

sudo systemctl status pihole-FTL.service

Restart DNS:

pihole restartdns

Bonus Tips to Level Up Your Setup

Use Unbound for Local DNS Resolution

Want total DNS privacy? Run Unbound locally:

sudo apt install unbound

Then configure Pi-hole to use 127.0.0.1#5335 as upstream DNS. Now, your DNS requests don’t leave your network unencrypted.

Add a Second Pi-hole for Redundancy

Two Pi-holes are better than one. Use a cheap Pi Zero for failover. Configure your DHCP to hand out both as DNS.

Block YouTube Ads (Kind of)

Pi-hole can’t block YouTube pre-rolls perfectly, but block domains like these to catch some junk:

r2---sn-p5qlsn7e.gvt1.com
youtubei.googleapis.com
s.ytimg.com

Don’t expect miracles—but it helps.


Pi-hole vs Browser Extensions (And Why Pi-hole Wins)

FeaturePi-holeuBlock Origin / AdBlock
Blocks Ads in Apps✅ Yes❌ No
Works Network-Wide✅ Yes❌ No
Lightweight✅ Yes⚠️ Browser Dependent
Privacy Logging✅ Fully Private❌ Sometimes Shares Logs
Centralized Control✅ Admin UI⚠️ Per Device

TL;DR: Pi-hole wins when you want total control over all devices.


Things Pi-hole Doesn’t Do (Just So We’re Clear)

Let’s not pretend Pi-hole is some digital unicorn. It doesn’t:

  • Encrypt your internet (use PiVPN or HTTPS)
  • Unblock geo-restricted content (no, you won’t get US Netflix this way)
  • Stop all YouTube ads (because YouTube is a sorcerer)

But it does a heck of a lot—especially when combined with PiVPN.


Final Thoughts: Should You Bother with Pi-hole + PiVPN?

If you’re:

  • Annoyed by ads and trackers
  • Tired of sketchy public Wi-Fi DNS
  • Into DIY cybersecurity
  • Already using a Raspberry Pi (or thinking about it)

Then YES—you need this combo in your life. It’s powerful, private, and honestly pretty fun to build.

I’ve been running mine for over a year. It saved my bacon more than once (like when an IoT camera tried calling servers in Russia—nope!). I learned more about DNS in two weeks than I did in two years. And now? My network feels… clean.


Techspiration to Close With

“The prudent sees danger and hides himself, but the simple go on and suffer for it.” — Proverbs 27:12 ESV

In this case, hiding yourself = running Pi-hole + PiVPN. Trust me, it’s worth the setup.
