In this Raspberry Pi Pi-hole tutorial, we will be setting up a network-wide ad blocker. A network-wide ad blocker works by acting as your DNS server.
What the network-wide ad blocker does is act as your DNS server. Your computers our routers will connect to it for DNS requests.
These DNS requests will then be filtered by the Raspberry Pi. Any DNS requests that match any that match a known ad host will be rejected meaning the connection will never meet your computer. Therefore the ad will never be loaded by the devices.
Network-wide ad blocking is a useful tool for stopping ads from appearing on devices that don’t have any easy to use adblock tool. It’s also a handy way to improve your network performance and bandwidth usage as the number of files downloaded during normal web browsing will be reduced.
It also has the added side effect of potentially improving the security and the privacy of your network, as some sites use relatively dodgy ad providers.
You can install the Pi-hole on other operating systems other than Raspbian. They have support for Ubuntu, Debian, Fedora, and CentOS 7 (Non-ARM).
If you decide to use the network-wide adblocker, please consider purchasing our Ultimate Books of Pi to help support the site and allow us to continually grow.
