#  Pi-hole
Pi-hole is a network-level ad-blocking solution that blocks ads before they reach your devices, improving browsing speed and privacy on your home network.  
 
 It is used as the prime DNS. All internet bound  traffic on the LAN network goes through the pinhole server which serves as the primary DNS for this traffic,  providing ad blocking and  site restriction  functionality. It blocks trackers and has a comprehensive list of malicious site blocks. In addition it acts as a local DNS, where local host records, both A records and CNAME aliases are created for a number of locally running services mapping IP addresses to host names.
