What is the Domain Name System (DNS)?
A DNS server is a kind of name server that oversees, keeps up and forms Internet domain names and their related associated. As such, a DNS server is an essential segment that executes the DNS (Domain Name System) protocol and provisions domain name resolution services to Web hosts and clients on an IP-based network.
Principally intended to find and convey sites to end clients over the Internet or a private system, a DNS server is created on normal equipment yet runs particular DNS programming. It is constantly associated with the Internet or a system.
A DNS server stores a database of various area names, organize names, Internet has, DNS records and other related information. The most fundamental capacity of a DNS server is to make an interpretation of a space name into its separate IP address. During a space name goals question, DNS records are looked, and whenever found, the area name record is returned. On the off chance that the area name isn’t enlisted or added to that DNS server, the inquiry is then passed to different DNS servers until the space name record is found.
DNS server programming comes in handfuls, if not many flavors. The best-realized adaptation is BIND, which is free and conveyed with Linux/Unix frameworks. On Microsoft frameworks, the Microsoft DNS is bundled as part of many Windows Server releases.
