DOMAIN NAME SYSTEM AND ITS WORKING PRINCIPLE

This article discusses the linkage of initial IP addresses of the Internet to specific computers, as well as the analysis of adding more devices and users to the network. Currently, while it is possible to access a website by entering a specific IP address in the browser, users strive to associate websites with memorable names. The article also examines the Domain Name System (DNS) and how it works. The components of the DNS system and the sequence of execution are presented. The Domain Name System (DNS) converts domain names into IP addresses, which are used by browsers to load web pages. Every device connected to the Internet has its own IP address, which is used by other devices to locate it. When users enter domain names into the browser’s address bar, DNS servers are responsible for translating these
domain names into digital IP addresses, guiding them to the correct website. DNS servers allow Internet users to enter simple abbreviated words, such as iiau.uz, in their browsers, which is very important to avoid remembering the IP addresses of every website.
