Root Server

A machine that has the software and data needed to locate name servers that contain authoritative data for the top-level domains (e.g., root servers know which name servers contain authoritative data for com, net, ch, uk, etc.). The root servers are, in fact, name servers and contain authoritative data for the very top of the Domain Name System (DNS) hierarchy. Currently, technical specifications limit the number of root servers to 13. These machines are currently located around the globe, in the U.S., the U.K., Sweden, and Japan.
