One of the tools that you use daily and at all times are web browsers to access the multiple sites, and regardless of the type of browser you use, these include a series of configurations that have been developed to optimize their use.
The most used browsers are Google Chrome, Firefox & Edge for its various features and functionality, and, like all browsers, include a DNS cache that allows us to access popular sites faster.

What is the DNS cache
DNS cache on web browsers helps you to get better performance when you access the intneret. That’s because the DNS cache reduces the request numbers that your computer needs to make to the servers, accelerating your browsing.
DNS cache is basically a file where all the most common websites and their server IPs are stored to access them quickly the next time.
But, why do you want to clear the DNS cache if it helps you to browse faster? Some of the reasons could be the following:
- You have changed the DNS servers of your network adapter and to apply that settings, you need to clear your browser DNS cache
- When some website changes their server from where the page loads, you may find some connection errors because your DNS cache tries to connect to the old server. In that case, clearing the DNS cache will help you to fix the issue
- You see multiple times errors on your browser that some common websites like Facebook and Google are untrusted. A quick clearing could help you with that too.
