Quad9

What is Quad9 and How Does It Work?

Quad9 is a free, open DNS recursive service that enhances internet security and privacy by blocking access to malicious domains. When you attempt to visit a website, Quad9 checks its IP address against a comprehensive, real-time list of known threats. If a match is found, Quad9 prevents the connection, safeguarding your devices from malware, phishing attempts, botnets, and other online dangers. It operates as a direct replacement for your Internet Service Provider's (ISP) or your network's default DNS server, requiring no complex setup or personal data submission.

The service is operated by the Quad9 Foundation, a Swiss-based non-profit organization dedicated to improving global internet security and privacy. Quad9 utilizes threat intelligence from over 25 leading cybersecurity companies, providing a robust defense against a wide array of online threats. Its commitment to privacy is underscored by its GDPR-compliant policies and the fact that it does not log user IP addresses, ensuring your online activities remain confidential and secure.

Getting started with Quad9 is straightforward and requires no sign-up or account creation. You can begin using the service by simply changing your device's DNS server settings to Quad9's IP addresses. These settings can be configured on individual devices, routers, or Wi-Fi access points to extend protection across your entire network, including IoT devices. Detailed setup guides are available to assist users in configuring Quad9 on various operating systems and devices.
