6 Easy Ways to Flush DNS Cache on Windows 11 and 10

Have you ever encountered trouble accessing a website or service and wondered why it wasn’t loading? This can sometimes be caused by an outdated DNS cache, which stores previously accessed website addresses. Fortunately, flushing the DNS cache is a simple solution to resolve these issues. In this article, we’ll guide you on how to flush DNS cache on Windows 11 and 10.

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.
