How to Setup a Local DNS Server with AdGuard Home

Managing network traffic and protecting connected devices from unwanted trackers, advertisements, and malicious domains has become essential for modern home and small office networks. While cloud-based filtering services offer a quick fix, they lack granular control and local domain resolution capabilities. Implementing a dedicated network-wide network blocker and resolver provides total control over your traffic.

By executing an adguard home setup local dns configuration, you take absolute command over your network layer. AdGuard Home acts as a centralized recursive or forwarded DNS server, blocking ads at the network level while empowering you to manage local hostnames, enforce safe search, and inspect real-time query logs across every connected device.

Prerequisites and Hardware Requirements

Before initiating the installation, you need a suitable host machine that remains powered on continuously. Because DNS resolution directly impacts network speed and availability, reliability is paramount.

• Dedicated Host: A low-power single-board computer (such as a Raspberry Pi 4 or 5), an always-on home server, or a lightweight virtual machine running Linux.
• Static IP Address: Your host machine must have a fixed local IP address assigned via your router’s DHCP reservation table.
• Administrative Access: Root or sudo privileges on the host operating system, along with administrative access to your primary home router.

Step 1: Installing AdGuard Home

The installation process varies depending on your operating system, but the official automated script supports most Linux distributions seamlessly. Log into your host machine via SSH and execute the official installation script:

curl -s -S https://raw.githubusercontent.com/AdguardTeam/AdGuardHome/master/scripts/install.sh | sh -s -- -v

This script automatically downloads the correct architecture binary, configures it as a system service, and starts the service immediately. Upon completion, the terminal outputs the URL and port required to access the initial web setup wizard (typically http://<your-host-ip>:3000).

Step 2: Completing the Initial Web Setup Wizard

Open a web browser on a device connected to the same network and navigate to the address provided by the installation script. Follow these steps in the wizard:

1. Interface Binding: Select the network interface on which AdGuard Home should listen. By default, binding to all interfaces (0.0.0.0) is recommended.
2. Admin Port: Choose a port for the web interface (port 3000 is standard for setup, but you can switch to standard HTTP/HTTPS ports later).
3. DNS Port: Keep the default DNS port set to 53. This ensures that client devices can query the server without appending custom port numbers.
4. Credentials: Create a secure administrative username and password to prevent unauthorized access to your filtering dashboard.

Step 3: Configuring Upstream DNS and Filtering Rules

Once inside the main dashboard, optimizing your upstream resolvers and blocklists ensures optimal performance and privacy.

Setting Upstream DNS Servers

Navigate to Settings > DNS Settings. Here, you define where AdGuard Home forwards valid queries that are not blocked locally. For enhanced privacy, configure encrypted upstream protocols such as DNS-over-HTTPS (DoH) or DNS-over-TLS (DoT) using providers like Cloudflare, Quad9, or AdGuard DNS.

Enabling Blocklists

Go to Filters > DNS Blocklists to enable curated lists that strip out advertisements, tracking beacons, and known malware domains. The default AdGuard DNS filter is a robust starting point. You can add community-driven lists (such as theoisplists or Steven Black’s unified hosts) to harden your defense further.

Step 4: Configuring Local DNS Records

One of the primary benefits of running your own resolver is managing local network devices via human-readable hostnames rather than IP addresses. To map local domains:

1. Navigate to Filters > DNS blocklists or directly to Settings > DNS Settings > Private DNS servers (depending on the version, locate the DNS blocklists / Custom filtering rules or Client settings).
2. Go to Filters > Custom filtering rules.
3. Add custom mapping entries using the standard hosts file syntax:

192.168.1.100 nas.home.arpa
192.168.1.50 printer.home.arpa
192.168.1.15 media-server.home.arpa

This configuration allows you to access your local network hardware effortlessly by typing nas.home.arpa into any browser on your network.

Step 5: Pointing Your Network to AdGuard Home

To enforce ad-blocking and local resolution network-wide, you must instruct your client devices to use your AdGuard Home server IP as their primary DNS server. You have two primary approaches for this:

• Method A (Router-Level – Recommended): Log into your home router’s admin panel, locate the LAN/DHCP settings, and change the Primary DNS server IP address to the static IP of your AdGuard Home host. Leave the secondary DNS blank or set it to a loopback to prevent clients from bypassing filters.
• Method B (Client-Level): Manually configure the DNS settings on individual computers, smartphones, and streaming boxes. This approach is ideal if you want to test filtering on a single device before rolling it out globally.

Frequently Asked Questions

Frequently Asked Questions

What happens to my network if the AdGuard Home host crashes?

If your AdGuard Home server goes offline and you configured a single DNS entry at the router level without a backup, client devices will temporarily lose domain resolution capabilities. To prevent outages, configure a secondary DNS server in your router settings—such as a public encrypted resolver—or set up a high-availability secondary AdGuard Home instance.

Can I bypass ad-blocking for specific trusted devices?

Yes. AdGuard Home features client management capabilities. You can create specific client profiles based on MAC or IP addresses, allowing you to disable filtering rules or change upstream resolvers for specific devices, such as a smart TV or a work laptop that requires unfiltered web access.

Does AdGuard Home slow down my internet connection?

In most cases, AdGuard Home actually improves perceived browsing speeds. Because advertisements, tracking scripts, and heavy analytics payloads are blocked locally before they ever touch your WAN connection, pages load faster and consume less bandwidth.

Conclusion

By completing an adguard home setup local dns deployment, you transform your home network into a secure, private, and lightning-fast environment. You no longer rely on external corporate resolvers that log your browsing habits, and you gain absolute mastery over local hostname resolution. Take the next step today: provision a dedicated host, spin up your instance, and experience a cleaner, faster internet across every connected screen in your home.
