What is 9.9.9.9? The "new" Quad9 DNS you will feel in love.

Quad9 ( 9.9.9.9 ) is a public DNS resolver service run by the Packet Clearing House and IBM. As it core, its main differentiator from other DNS resolvers is that it automatically blocks domains known to be associated with malicious activity. In addition to standard DNS service, it also offers an experimental DNS over TLS service over port 853.
