A DDoS protected DNS service is designed to defend against cyber attacks that aim to overwhelm servers with traffic. It uses technologies like Anycast routing and load balancing to distribute traffic across multiple servers and may also employ techniques like rate limiting and traffic filtering. This helps ensure the availability and reliability of online services and applications, minimizing the risk of downtime, data loss, and reputational damage caused by DDoS attacks.
