DNS, or Domain Name System, is a system for translating domain names into IP addresses that are used to identify computers and other devices on the internet. The system allows users to access websites and other internet services using easily memorable domain names instead of numeric IP addresses.
The functioning of DNS is based on a hierarchical system with multiple levels of domains. Each domain consists of a string of characters separated by dots, where the highest level corresponds to the top-level domains such as .com, .org or .gov. Below these levels are other levels, such as .co.uk or .edu.
DNS works on the principle of queries and responses. When a user enters a domain name into their web browser, the browser sends a query to the DNS server, which translates the domain name into the corresponding IP address. The browser then uses this IP address to connect to the website.
Management of the system involves configuring servers and setting records that contain information on how to translate domain names into IP addresses. DNS management can be performed using specialized tools and services that allow domain administrators to make changes to DNS records and address any problems with domain name translation.
This system is a critical component of internet infrastructure and ensures the efficient functioning of the entire internet space. Proper configuration and management of DNS are necessary to ensure correct translation of domain names into IP addresses, allowing users easy access to websites and other internet services.
The DNS cache, also known as DNS cache, is a critical component of internet infrastructure. It stores recent queries to any DNS servers, significantly speeding up the loading of web pages on your computer. When a user enters a web address into a browser, the device first asks a DNS server for the corresponding IP … Read more
