Pi-hole

Pi-hole is a Linux network-level advertisement and Internet tracker blocking application which acts as a DNS sinkhole and optionally a DHCP server, intended for use on a private network. It is designed for low-power embedded devices with network capability, such as the Raspberry Pi, but can be installed on almost any Linux system. As well as importing externally prepared blocklists, Pi-hole can be configured to block specific websites or apply parental controls.
