Pi-hole is an open-source software that acts as a DNS server which blocks advertisements and disables trackers on a network-wide level. I configured my instance to run on a headless Raspberry Pi Zero connected to my router through Ethernet. This device has improved my network’s privacy by preventing targeted advertising and security by stopping malicious advertisements from being served.
