Quad9 is a free, recursive, anycast DNS platform that provides end users robust security protections, high-performance, and privacy. An open DNS recursive service for free security and high privacy. Quad9 is the only major public DNS resolver with a founding charter that is centered around user privacy & security. Our mission is to help end users keep their data under their own control and to reduce risks from malicious content. Quad9 has several different service offerings for recursive DNS features. Each is represented by a different IP address (or, in some cases, hostname), which you use to configure your systems. Quad9 systems are distributed worldwide in more than 200 locations in 90 nations, with extensive further expansion scheduled. Quad9 has servers located primarily at Internet Exchange points, which are where the highest concentration of interconnections occur within a typical region between networks. Setting up Quad9 takes only a few minutes and is a very straightforward process. We offer setup guides for individual devices as well as full networks. Are you protected by Quad9?
