Successfully setup a DNSCrypt server. It is free, non-logging, daily keys rotation, uncensored, recursive DNS server with DNSSEC support.
Privacy and security basically sums it up. Two of the biggest issues these days.
DNSCrypt is one of the methods to give back your privacy and security. It encrypts DNS queries which otherwise are sent in plain text, even when you make use of a VPN or visit a website using SSL/TLS. Meaning that without DNS encryption anyone can spy on the connection to know what you are accessing.
According to DNSCrypt official website:
DNSCrypt is a protocol that authenticates communications between a DNS client and a DNS resolver. It prevents DNS spoofing. It uses cryptographic signatures to verify that responses originate from the chosen DNS resolver and haven’t been tampered with.
