What is DNS

DNS stands for Domain Name System. It is a decentralized naming system for computers, services, or any resource connected to the internet or a private network. The DNS system translates human-readable domain names (such as google.com) into IP addresses (such as that are used by computers to communicate with each other over the internet.

When a user types a URL (Uniform Resource Locator) into their web browser, the browser sends a request to a DNS resolver to resolve the domain name in the URL into an IP address. The resolver queries a chain of DNS servers until it finds the IP address associated with the domain name. Once the resolver obtains the IP address, the web browser can then use it to connect to the web server hosting the website and retrieve the content requested by the user.

DNS is an essential component of the internet infrastructure, and it enables the internet to function as a globally connected network of devices and services.
