If you're having trouble loading a website or viewing certain pages, you should first try clearing your DNS cache. This guide will show you how to flush the DNS cache on Windows 10 and 11.

Follow these simple steps, and you should be able to fix your problem in no time!

What Is a DNS Cache and Why Would You Need To Flush It?

Windows maintains a temporary database of all successful and unsuccessful website visits, called the DNS cache.

The DNS cache is a log of past DNS lookups that are stored by the operating system or by the web browser. By saving a local copy of a DNS lookup, your OS or browser can load websites much faster by quickly retrieving the corresponding IP address

In most cases, your Internet Service Provider automatically configures your connection to make it simpler for you to access websites and services that you frequently use.  It’s important to keep in mind that the DNS cache will eventually clear itself due to its TTL feature, so it’s not always necessary to do it manually.

Furthermore, although a DNS cache can speed up loading times, it might also pose security risks. So, flushing it can help address connectivity issues, data privacy concerns, or security threats. 

Here are some of the common reasons why you might want to clear your DNS cache:

  • 404 error appears on your screen when you try accessing sites
  • You want to avoid DNS spoofing
  • You can’t access a particular website
  • You wish to keep your search history confidential
