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. The Servers are a critical part of DNS infrastructure because they provide the initial data in resolving human-readable host names into IP addresses that are used in communication between Internet hosts.

The Server:

Maintains databases for:
- All the records in the root zone;
- A list of TLD nameservers, which are the authoritative name servers for the top-level domains (TLDs);
Directly answers requests of DNS resolvers for records in the root zone and appropriate TLD nameservers.
