If you’re tired of ads cluttering your browsing experience across all your devices—from smartphones to smart TVs—it’s time to implement network-wide ad blocking. Pi-hole offers an elegant DNS-level solution that blocks ads and trackers for every device on your network without requiring individual software installation. In this guide, I’ll walk you through setting up Pi-hole, compare it with AdGuard Home, and explain why Pi-hole has become my go-to choice for homelab DNS management.
What is Pi-hole?
Pi-hole is a DNS sinkhole that acts as a network-wide ad blocker. Instead of filtering ads at the browser level, Pi-hole intercepts DNS requests from all devices on your network and blocks queries to known advertising and tracking domains before they ever reach your devices.
When a device on your network tries to load an advertisement, Pi-hole checks the domain against its blocklists. If the domain is on the blocklist, Pi-hole returns a non-routable address like 0.0.0.0, effectively preventing the ad from loading. For legitimate content, Pi-hole forwards the DNS query to your chosen upstream DNS provider and returns the result.
Key Benefits
Network-wide protection: Block ads on all devices including smart TVs, IoT devices, smartphones, and tablets—even those that don’t support traditional ad blockers.
Improved performance: Pages load faster without ads consuming bandwidth and processing power. Pi-hole also caches DNS queries locally, reducing DNS resolution times.
Enhanced privacy: Block tracking domains and analytics services across your entire network, reducing the digital footprint of all your devices.
Lightweight and efficient: Runs smoothly on minimal hardware, making it perfect for Raspberry Pi or resource-efficient LXC containers.
Network insights: The web dashboard provides detailed statistics about DNS queries, helping you understand what your devices are communicating with.

- Update your system:
sudo apt update && sudo apt upgrade -y - Assign a static IP address (if not done via router):
sudo nano /etc/dhcpcd.conf
Add the following lines (adjust for your network):
interface eth0
static ip_address=192.168.1.100/24
static routers=192.168.1.1
static domain_name_servers=1.1.1.1 8.8.8.8
Reboot to apply changes:
sudo reboot
- Run the Pi-hole installer:
curl -sSL https://install.pi-hole.net | bash
Note: While piping to bash is controversial, this is the official installation method. You can review the script at https://install.pi-hole.net before running it if you prefer.
- Follow the installer prompts:
- Confirm static IP address setup
- Select network interface (eth0 for Ethernet, wlan0 for Wi-Fi)
- Choose upstream DNS provider (Cloudflare 1.1.1.1, Google 8.8.8.8, OpenDNS, etc.)
- Select default blocklists (recommended: Yes)
- Install web admin interface (recommended: Yes)
- Enable query logging (your choice based on privacy preferences)
- Save the admin password displayed at the end of installation. You can change it later with:
pihole -a -p - Access the web interface:
Navigate to
http://YOUR_PI_IP/admin(e.g.,http://192.168.1.100/admin)
Configure Your Network
To enable network-wide ad blocking, configure your router to use Pi-hole as the DNS server:
- Log into your router’s admin panel
- Find DHCP/DNS settings
- Set primary DNS to your Pi-hole IP address
- Leave secondary DNS blank (or set to a backup Pi-hole)
- Save and reboot router if necessary
Alternatively, manually configure DNS on individual devices for testing before network-wide deployment.

Post-Installation Configuration
Once Pi-hole is installed, there are several optimizations and configurations worth considering:
1. Adding Additional Blocklists
Navigate to Settings → Adlists and add additional blocklists. Some popular options:
https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts
https://dbl.oisd.nl
https://v.firebog.net/hosts/lists.php?type=tick
After adding lists, update gravity:
pihole -g
2. Whitelisting Essential Domains
Some domains may need to be whitelisted to prevent breaking functionality:
- Settings → Whitelist
- Add domains that are incorrectly blocked
- Common examples: update servers, CDN domains, authentication services
3. Configuring Upstream DNS
For enhanced privacy, consider using encrypted DNS or recursive DNS with Unbound:
Using Cloudflare DNS:
- Settings → DNS → Upstream DNS Servers
- Select Cloudflare (1.1.1.1 and 1.0.0.1)
Setting up Unbound (recursive DNS):
apt install -y unbound
curl -o /etc/unbound/unbound.conf.d/pi-hole.conf https://docs.pi-hole.net/guides/dns/unbound/
systemctl restart unbound
Then configure Pi-hole to use Unbound:
- Settings → DNS → Upstream DNS Servers
- Custom 1:
127.0.0.1#5353 - Uncheck all other upstream servers
4. Enable DHCP (Optional)
If your router’s DHCP server is limited, Pi-hole can act as your DHCP server:
- Settings → DHCP
- Enable DHCP server
- Configure IP range, router/gateway, and domain
- Important: Disable DHCP on your router first
5. Local DNS Records
Add local DNS entries for your homelab services:
- Local DNS → DNS Records
- Add domain names and corresponding IP addresses
- Example:
proxmox.home.lab→192.168.1.10
This eliminates the need to remember IP addresses for your homelab services.
Monitoring and Maintenance
Web Dashboard
The Pi-hole dashboard provides comprehensive statistics:
- Total queries
- Queries blocked (percentage)
- Top blocked domains
- Top clients
- Query types
- Forwarding destinations
Command-Line Tools
Pi-hole includes powerful CLI tools:
# Update Pi-hole
pihole -up
# Update blocklists
pihole -g
# Restart Pi-hole services

pihole -a -p
Regular Maintenance
- Update Pi-hole: Run
pihole -upmonthly - Update blocklists: Automatic by default (weekly), or manually with
pihole -g - Review statistics: Identify blocked domains that might need whitelisting
- Backup configuration: Export your settings regularly
Redundancy and High Availability
For critical homelab infrastructure, consider running two Pi-hole instances:
Primary and Secondary Setup
- Install Pi-hole on two separate devices/containers
- Configure router to use both as DNS servers:
- Primary DNS: Pi-hole 1 (192.168.1.100)
- Secondary DNS: Pi-hole 2 (192.168.1.101)
Keeping Instances in Sync
Use Gravity Sync to synchronize configurations between Pi-holes:
# On both Pi-hole instances
curl -sSL https://raw.githubusercontent.com/vmstan/gravity-sync/master/GS_INSTALL.sh | bash
Configure gravity-sync to sync:
- Blocklists
- Whitelists
- Blacklists
- Local DNS records
- DHCP settings
This ensures you only need to manage one Pi-hole while maintaining redundancy.
Troubleshooting Common Issues
Websites Not Loading
Problem: Legitimate websites fail to load or function properly.
Solution:
- Check query log to identify blocked domains
- Whitelist necessary domains
- Temporarily disable Pi-hole (
pihole disable 300) to confirm it’s the cause
High False Positive Rate
Problem: Too many legitimate domains are blocked.
Solution:
- Review and adjust blocklists
- Remove aggressive blocklists
- Use more curated lists like OISD
Pi-hole Not Blocking Ads
Problem: Ads still appear on some websites.
Solution:
- Verify devices are using Pi-hole as DNS (check router settings)
- Some ads are served from the same domain as content (YouTube, Hulu)
- Update blocklists:
pihole -g - Check if domains are on whitelist
YouTube Ads Still Showing
Problem: Pi-hole doesn’t block YouTube ads.
Limitation: YouTube serves ads from the same domains as content, making DNS-level blocking impossible without breaking functionality. Solutions:
- Use browser extensions like uBlock Origin
- Consider YouTube Premium
- Accept that DNS blocking has limitations
Performance Considerations
Pi-hole is remarkably efficient, but there are ways to optimize performance:
DNS Caching
Pi-hole caches DNS responses, significantly speeding up repeat queries. You can monitor cache effectiveness in the dashboard.
Rate Limiting
Configure rate limiting to prevent DNS amplification attacks:
Edit /etc/dnsmasq.d/02-pihole-rate-limit.conf:
rate-limit=1000/60/60
Log Management
Query logging can impact performance on high-traffic networks. Consider:
- Reducing log retention period
- Disabling logging if privacy is paramount
- Using anonymous mode (logs without client identification)
Security Best Practices
- Change default password immediately after installation
- Enable HTTPS for the web interface (requires certificate setup)
- Restrict web interface access to local network only
- Keep Pi-hole updated with
pihole -up - Use strong upstream DNS providers (Cloudflare, Quad9)
- Consider recursive DNS (Unbound) for maximum privacy
- Regular backups of configuration via teleporter (Settings → Teleporter)
