Before we move forward, it is essential to understand what a DNS cache is. In basic terms, DNS cache is a feature that stores information about your recently accessed websites and acts as a temporary database to speed up the browsing experience. However, if a website’s IP address changes, your computer may still try to access the old address due to the cached DNS information. You may encounter errors when attempting to access the site. Hence, to fix this, you must flush DNS cache. Let’s show you how.

Afterward, you will see a message stating that the DNS resolver cache has been flushed. If this method fails, you can check out the following method.
