What is the DNS cache?

DNS cache in web browsers helps you get better performance when accessing the intneret. This is because the DNS cache reduces the number of requests your computer needs to make to the servers, speeding up your browsing.

The DNS cache is basically a file where all the most common websites and the IPs of your servers are stored to access them quickly next time.

But why do you want to clear your DNS cache if it helps you browse faster? Some of the reasons could be the following:

  • You have changed the DNS servers on your network adapter, and to apply those settings, you must clear your browser’s DNS cache.
  • When some website changes its server from where the page is loaded, you may encounter some connection errors because your DNS cache tries to connect to the old server. In that case, clearing the DNS cache will help you fix the problem.
  • You see various errors in your browser that some common websites like Facebook and Google are not trustworthy. A quick clean might help you with that, too.
