Pi-Hole

  Pi-Hole is a network-wide ad-blocker. Instead of installing ad-blockers on every device and every browser, you can install Pi-Hole once on your network and it will protect all of your devices. Because it works differently than a browser-based ad-blocker.

💨 DNS-based(Domain Name System) "black hole" devices, such as Pi-hole, are a popular method used to block ads and tracking on a local network.
💨 Devices like Pi-hole work by altering DNS lookups to unwanted destinations so that they return invalid IP addresses. 
💨 So for instance, when your browser tries to connect to Double click to retrieve an ad, your network can't reach their server. So the lookup fails and the ad is not displayed.
