Cloud flare DNS

by | Sep 6, 2024 | Technology

Cloudflare DNS is a domain name system (DNS) service provided by Cloudflare, known for its speed, security, and privacy features. Here’s an overview of its key aspects:

  1. Speed: Cloudflare DNS (1.1.1.1) is designed to provide faster DNS resolution by caching queries and reducing latency. It’s among the fastest DNS resolvers globally.
  2. Security: Cloudflare offers enhanced security through features like DNS over HTTPS (DoH) and DNS over TLS (DoT), which encrypt DNS queries, protecting them from eavesdropping and tampering.
  3. Privacy: Unlike many DNS services, Cloudflare focuses on user privacy. It promises not to log personal information and works with third-party auditors to verify this.
  4. Public DNS Resolver: 1.1.1.1 is the primary IP address for Cloudflare’s public DNS resolver. It’s free to use, and you can configure your devices to use it instead of your ISP’s DNS.
  5. Protection Against DDoS: For websites and servers, Cloudflare DNS provides protection against Distributed Denial of Service (DDoS) attacks by distributing DNS queries and shielding your website from overloads.
