Raspberry Pi Ad Blocker: Pi-hole Complete Setup

Pi-hole is a network-wide ad blocker that runs on your Raspberry Pi, blocking advertisements and trackers for every device on your home network. No more installing ad blockers on each device — your Pi handles it all at the DNS level. This guide shows you how to set it up optimally for Indian users.

What is Pi-hole and How Does It Work

Pi-hole acts as a DNS sinkhole. When any device on your network tries to load an ad, tracker, or malware domain, Pi-hole intercepts the DNS request and returns a blank response instead of the ad server’s IP address.

• Network-wide: Blocks ads on phones, tablets, smart TVs, and IoT devices.
• No per-device setup: Configure once at the router level.
• Blocks trackers: Stops analytics services from tracking your browsing.
• Speeds up browsing: Pages load faster without ads downloading.
• Saves bandwidth: Reduces data usage by 15-30% on average.

Hardware Requirements

Pi-hole is extremely lightweight and runs on any Raspberry Pi model:

• Raspberry Pi Zero 2 W, Pi 3, Pi 4, or Pi 5 (even a Pi Zero W works)
• MicroSD card (8GB minimum, 16GB recommended)
• Ethernet connection (recommended for DNS reliability)
• Power supply for your Pi model

Pi-hole uses only about 50MB of RAM and minimal CPU, making it perfect for a dedicated always-on Pi.

Installing Pi-hole on Raspberry Pi

# Ensure your Pi has a static IP address first
# Check your current IP
hostname -I

# Set a static IP via dhcpcd (if not using NetworkManager)
sudo nano /etc/dhcpcd.conf
# Add at the end:
# interface eth0
# static ip_address=192.168.1.50/24
# static routers=192.168.1.1
# static domain_name_servers=1.1.1.1 8.8.8.8

# Reboot and verify the static IP
sudo reboot
hostname -I

# Install Pi-hole (one-line installer)
curl -sSL https://install.pi-hole.net | bash

# Follow the interactive installer:
# 1. Select interface: eth0 (Ethernet)
# 2. Select upstream DNS: Google, Cloudflare, or custom
# 3. Select blocklists: default lists are a good start
# 4. Install web admin interface: Yes
# 5. Install lighttpd web server: Yes
# 6. Enable query logging: Yes
# 7. Privacy mode: Show everything (for your home network)

# Note down the admin password shown at the end
# Or set a new one:
pihole -a -p your-new-password

# Access the dashboard
# http://192.168.1.50/admin

Configuring Your Router to Use Pi-hole

For Pi-hole to work for all devices, your router needs to use the Pi as its DNS server:

Method 1: Router DHCP DNS (Recommended)

1. Log into your router admin panel (192.168.1.1)
2. Find DHCP settings
3. Set Primary DNS to your Pi’s IP (e.g., 192.168.1.50)
4. Set Secondary DNS to your Pi’s IP as well (not an external DNS, or devices may bypass Pi-hole)
5. Save and restart the router
6. Renew DHCP on your devices or reboot them

Method 2: Per-Device DNS

If your router does not support custom DNS, configure each device manually:

• Windows: Network Settings > IPv4 > DNS: 192.168.1.50
• Android: WiFi > Advanced > DNS: 192.168.1.50
• iOS: WiFi > Configure DNS > Manual > 192.168.1.50

Adding Custom Blocklists for Indian Ads

The default blocklists work well but miss many India-specific ad networks. Add these:

# Go to Pi-hole Admin > Adlists
# Add these Indian ad-blocking lists:

# Commonly used lists:
https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts
https://raw.githubusercontent.com/anudeepND/blacklist/master/adservers.txt
https://raw.githubusercontent.com/anudeepND/blacklist/master/CoinMiner.txt
https://v.firebog.net/hosts/AdguardDNS.txt
https://v.firebog.net/hosts/Easylist.txt

# After adding lists, update gravity:
pihole -g

Whitelist common Indian services: Some Indian banking and government websites may break. Whitelist them in Pi-hole Admin > Whitelist:

# Common whitelist entries for Indian users
pihole -w razorpay.com
pihole -w api.razorpay.com
pihole -w checkout.razorpay.com
pihole -w paytm.com
pihole -w digilocker.gov.in
pihole -w aadhar.uidai.gov.in

The Pi-hole Dashboard and Statistics

The Pi-hole dashboard provides valuable insights:

• Total queries: How many DNS requests your network makes (typically 5,000-50,000 per day)
• Queries blocked: Usually 15-40% of all queries are ads/trackers
• Top blocked domains: See which ad networks target you most
• Top clients: Identify which devices make the most requests
• Query log: See every DNS request in real-time

Access the dashboard at http://pi.hole/admin or http://<pi-ip>/admin.

Advanced Configuration and Maintenance

# Update Pi-hole
pihole -up

# Update blocklists (gravity)
pihole -g

# View real-time log
pihole -t

# Check Pi-hole status
pihole status

# Disable Pi-hole temporarily (useful for debugging)
pihole disable 5m   # Disable for 5 minutes
pihole enable       # Re-enable

# Backup your Pi-hole settings
# Admin > Settings > Teleporter > Backup

# Set up DHCP server in Pi-hole (alternative to router DHCP)
# Admin > Settings > DHCP > Enable DHCP server
# Then disable DHCP on your router

Frequently Asked Questions

{“@context”: “https://schema.org”, “@type”: “FAQPage”, “mainEntity”: [{“@type”: “Question”, “name”: “Does Pi-hole block YouTube ads?”, “acceptedAnswer”: {“@type”: “Answer”, “text”: “Pi-hole has limited effectiveness against YouTube ads because Google serves ads from the same domains as video content. For YouTube ads, you still need a browser-based ad blocker like uBlock Origin. Pi-hole blocks most other website ads effectively.”}}, {“@type”: “Question”, “name”: “Will Pi-hole slow down my internet?”, “acceptedAnswer”: {“@type”: “Answer”, “text”: “No, Pi-hole actually speeds up your internet. DNS queries to the Pi are faster than external DNS servers (sub-millisecond vs 20-50ms). Plus, blocked ads mean less data to download, so pages load faster.”}}, {“@type”: “Question”, “name”: “Can I run Pi-hole and a VPN on the same Raspberry Pi?”, “acceptedAnswer”: {“@type”: “Answer”, “text”: “Yes, Pi-hole and WireGuard work excellently together. Configure WireGuard to use the Pi’s IP as its DNS server, and all VPN traffic will be ad-free too.”}}, {“@type”: “Question”, “name”: “How much electricity does Pi-hole use running 24/7?”, “acceptedAnswer”: {“@type”: “Answer”, “text”: “A Raspberry Pi running Pi-hole consumes 2-4 watts, costing approximately u20b910-20 per month at Indian electricity rates. This is negligible compared to the bandwidth savings.”}}, {“@type”: “Question”, “name”: “What happens if the Pi-hole Raspberry Pi goes offline?”, “acceptedAnswer”: {“@type”: “Answer”, “text”: “If Pi-hole goes down, DNS resolution fails and internet may appear to stop working. Set a secondary DNS on your router (like 1.1.1.1) as a fallback, though this means ads may appear on some devices when Pi-hole is down.”}}]}
