Domain Name System Root. Domain names are mapped to IP addresses through this process for example. A DNS zone may consist of only one domain or may consist of many domains and sub-domains depending on the administrative choices of the zone manager.
The Domains Name Server. The forest root name is a Domain Name System DNS name that consists of a prefix and a suffix in the form of prefixsuffix. The resolver then queries a DNS root nameserver.
At the end of the name there may be a dot to separate the empty name corresponding to the root domain.
The mapping of domain names to IP addresses works in a hierarchical order using DNS zones. DNS associates information with domain names and a great deal of online activity makes use of it. Its job is to query name servers to find and return the authoritative name server for the requested domain. It directly answers requests for records in the root zone and answers other requests by returning a list of the authoritative name servers for the appropriate top-level domain.
