DNS (Domain Name System) resolution is a crucial behind-the-scenes process that enables us to access websites, send emails, and connect to various services on the internet. While it might seem like magic, it’s a well-defined process that involves multiple steps. In this step-by-step guide, we’ll demystify DNS resolution and explain how it works.

Everything starts with a user’s request to access a website or service. This request typically comes in the form of a URL (Uniform Resource Locator) entered into a web browser’s address bar or a similar input method. For example, when you type “www.example.com” into your browser, you’re initiating a DNS resolution process.
