About Quad9 DNS
Quad9 is a free, recursive, anycast DNS platform operated by a Swiss-based non-profit foundation. It provides a security solution that replaces default ISP or enterprise DNS configurations to block lookups of malicious hostnames. Using threat intelligence from over 25 providers, the service protects computers, mobile devices, and IoT systems against malware, phishing, and botnets. The platform operates over 230 resolver clusters globally to improve performance and does not log IP addresses, with a focus on user privacy and data sovereignty.
