Pi-hole is a free and open-source software that can be installed on a Raspberry Pi to function as a network-wide ad-blocker and DNS server. Pi-hole is designed to block advertisements, tracking, and malware domains at the network level, which means that all devices on a network can benefit from Pi-hole’s ad-blocking capabilities.
To install Pi-hole on a Raspberry Pi 4, you first need to ensure that you have Raspbian Buster or later installed on your Raspberry Pi. Once you have confirmed that, you can follow these steps to install Pi-hole:
- Open a terminal window on your Raspberry Pi and type the following command to download and install Pi-hole:
- curl -sSL https://install.pi-hole.net | bash
- Follow the on-screen instructions to complete the installation. You will be prompted to set a static IP address for your Raspberry Pi and configure your DNS settings.
- Once the installation is complete, you can access the Pi-hole dashboard by opening a web browser and navigating to the IP address of your Raspberry Pi. You can then configure Pi-hole to block specific domains and enable additional features such as DHCP and DNSSEC.
