The Domain Name System maintains the domain name hierarchy and provides translation services between it and the address spaces. Internet name servers and a communication protocol implement the Domain Name System. A DNS name server is a server that stores the DNS records for a domain; a DNS name server responds with answers to queries against ...
The top hierarchy of the Domain Name System is served by the root name servers maintained by delegation by the Internet Corporation for Assigned Names and Numbers (ICANN). DNS servers, which are located all over the world, translate domain names into IP addresses, giving them control over which server a user may access via a given domain.
In computing, a directory service or name service maps the names of network resources to their respective network addresses.It is a shared information infrastructure for locating, managing, administering and organizing everyday items and network resources, which can include volumes, folders, files, printers, users, groups, devices, telephone numbers and other objects.
A root name server is a name server for the root zone of the Domain Name System (DNS) of the Internet. 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 (TLD).
Examples are the Domain Name System (DNS) which translates domain names to Internet Protocol (IP) addresses and the Dynamic Host Configuration Protocol (DHCP) to assign networking configuration information to network hosts. Authentication servers identify and authenticate users, provide user account profiles, and may log usage statistics.
A DNS zone is implemented in the configuration system of a domain name server. Historically, it is defined in the zone file , an operating system text file that starts with the special DNS record type Start of Authority (SOA) and contains all records for the resources described within the zone.
The software and operating system used to run a domain controller usually consists of several key components shared across platforms.This includes the operating system (usually Windows Server or Linux), an LDAP service (Red Hat Directory Server, etc.), a network time service (ntpd, chrony, etc.), and a computer network authentication protocol (usually Kerberos).

Examples include the Domain Name System (DNS), Network Information Service and Multicast DNS (mDNS). IP addresses for devices on the local segment can in turn be resolved to MAC addresses by invoking the Address Resolution Protocol (ARP). Unix operating systems associate both an alphanumeric name and a user or group ID with each user account or ...
