Using Premium DNS, expands your website’s opportunities for uptime. Dotkeeper collaborates with strong providers that give your company the highest possible security and availability, and support IPv6, DNSSEC and more. Dotkeeper uses IP Anycast, a network of name servers spread all over the world, all broadcasting simultaneously from the same IP address. In order to affect the service, all of the servers worldwide have to be knocked out at once, as opposed to Unicast DNS where the effects would be noticed even if only a single servers goes down.
