An open DNS recursive service for free security and high privacy
An open DNS recursive service named Quad9 has been launched, providing free security and high privacy for Internet users. This service replaces the default ISP or enterprise DNS configuration on your computer, mobile device, or IoT systems. Quad9 blocks lookups of malicious host names using an up-to-the-minute list of threats, protecting against malware, phishing, spyware, and botnets.
It also improves performance while guaranteeing privacy. The Quad9 Foundation, based in Switzerland, operates this service with a mission to create a safer and more robust Internet for everyone.
