Advanced DNS DDoS (Distributed Denial of Service) Protection is just one of the features included when you sign up to PremiumDNS with Namecheap. It uses Anycast DNS which stores DNS records across multiple servers around the world. This helps to redistribute DNS queries across the network at the time of an attack, so denial of service can be avoided.Another way of securing against DDoS attacks is with advanced Content Delivery Network (CDN) services. This is another global network for the content that populates your website. In the time of high traffic or a DDoS attack, it can also redistribute the content accordingly.
