DNS cache plays a vital role in web browsing by storing critical data such as domain names and IP addresses. This cache optimizes your online experience by facilitating quicker access to websites. However, there are situations where clearing the DNS cache becomes essential, especially when you encounter connectivity issues or outdated data. 

This guide will take you through the steps to clear DNS cache on three of the most popular web browsers: Microsoft Edge, Google Chrome, and Mozilla Firefox. By following these easy-to-understand instructions and explanations, you can ensure that your browsing remains seamless and up-to-date.
