Root name server (alternatively spelled, root nameserver or, simply, root server; hereinafter, the Server) is a name server for the root zone of the Domain Name System (DNS) of the Internet.

Functions

The Server:

  1. Maintains databases for:

the authoritative name servers for the appropriate top-level domain (TLD)

  1. Directly answers requests for records in the root zone; and
  2. Answers

requests by returning a list of the authoritative name servers for the appropriate top-level domain (TLD). The root name servers are a critical part of the Internet infrastructure because they are the first step in translating (resolving) human readable host names into IP addresses that are used in communication between Internet hosts.
