DNS, or Domain Name System, is a system that converts human-readable domain names (eg tseivo.com) into IP addresses used by computers to identify servers on the network.
Basic functions of DNS
Convert names to IP addressesDNS allows users to use domain names they understand instead of numerical IP addresses to access websites and other resources on the Internet.
Domain distributionDNS is responsible for the hierarchical organization of domain names and the distribution of their management between different registrars and DNS servers.
Availability and scalingDNS provides scalability and availability, allowing multifunctional servers to process requests to convert domain names into corresponding IP addresses.
DNS works on the basis of a distributed database, which includes a hierarchical structure of domains. This structure includes root domains, national top-level domains (eg.com, .org, .net), and specific domains (eg tseivo.com). DNS servers are located around the world and interact with each other to ensure the conversion of domain names into corresponding IP addresses.
DNS was developed in 1983 and set as the Internet standard. One of its main purposes was to facilitate access to resources using human-readable domain names, instead of remembering numerical IP addresses.
