Quad9
A public and free DNS service for a better security and privacy
Quad9 is a free, privacy-focused public DNS resolver operated by the Swiss-based Quad9 Foundation. It blocks malicious domains in real time using threat intelligence from over 25 cybersecurity providers, protecting users from malware, phishing, and botnets. No IP addresses are logged, no account is required, and the service is GDPR-compliant.
Users point their device or router DNS settings to Quad9's servers, which automatically block lookups of known malicious hostnames using real-time threat intelligence while never logging personal IP data.
General internet users, businesses, and organizations seeking free DNS-level security and privacy
