Description

Quad9 is a free, secure, and privacy-focused Domain Name System (DNS) service that helps protect internet users from visiting malicious websites. It is designed to protect users from cyber threats such as phishing, malware, botnets, and other cyber-attacks by blocking known malicious domains. Quad9 is a global service that is available to anyone with access to the internet. It works by routing all DNS requests to its servers, which then check the requested domain against a variety of threat intelligence sources. If a domain is found to be malicious, the request is blocked. Quad9 also provides users with additional features such as IPv6 support and DNS over TLS/HTTPS. Additionally, Quad9 does not log user data or store IP addresses, ensuring user privacy.
