The Domain Name System, or DNS, is often described as the internet’s address book. When you type a website address (like www.example.com) into your browser, DNS works behind the scenes to translate that address into a series of numbers, known as an IP address, which computers use to identify each other. Without DNS, browsing the internet would be a lot harder, requiring users to memorize long strings of numbers for each website. In this guide, we’ll explore how DNS works, why it’s essential, and how it helps keep the internet running smoothly. ...
