Quad9

Security and privacy-focused DNS resolver

DNS services form the backbone of internet navigation, translating human-readable domain names into IP addresses. Quad9enhances this critical infrastructure with privacy protection and security features that prevent ISPs and other entities from monitoring your browsing habits. By implementing DNS-over-HTTPS or DNS-over-TLS protocols, your DNS queries become encrypted and indistinguishable from regular web traffic.

Beyond privacy, Quad9 provides robust security features including real-time blocking of malware domains, phishing sites, and advertising networks at the DNS level before they can load. The service offers customizable filtering policies for families and organizations, detailed analytics of blocked threats, and global server infrastructure that ensures fast resolution times while maintaining privacy through minimal logging policies and regular third-party audits.
