DNS

DNS, or Domain Name System, is a hierarchical and decentralized naming system for computers, services, or other resources connected to the internet or a private network. It converts easy-to-remember domain names into numerical IP addresses required for locating and identifying devices and services. DNS is fundamental to the operation of the internet, enabling users to access websites and services using familiar names instead of numeric addresses.

What is DNS?

DNS stands for Domain Name System. It is the protocol that allows users to access websites and services using human-readable domain names instead of numeric IP addresses. When a domain name is entered in a browser, DNS servers resolve it to the corresponding IP address, enabling communication between devices on the internet. DNS is essential for usability and connectivity across the web.
