Abstract
This disclosure describes systems, methods, and apparatus for sharing DNS answers between DNS server systems within a DNS cluster, between proxy servers, and/or between DNS server systems of different DNS clusters. When a DNS answer is obtained by a DNS server system, the answer can be shared with peer DNS server systems within a same DNS cluster or with DNS server systems having a logical relation to the first DNS server system (e.g., geographic relationship), but being in different DNS clusters. Proxy servers may also mediate communication between a client and the DNS clusters. These proxies can also include the ability to share DNS answers between each other.
