How to Flush DNS Windows 10 / 11 (Clear Windows DNS Cache)

How to Flush DNS Windows 10 / 11 (Clear Windows DNS Cache). If you are having trouble connecting to websites and applications on Windows 11 despite deleting the temporary files of Windows and the system caches, the culprit might be an outdated or corrupted DNS cache.

Your computer keeps a temporary file called the DNS cache with the names of all the hosts and IP addresses you’ve ever visited through any web browser. It helps in reducing loading time while browsing.

But there are times when a website’s IP address changes but hasn’t been updated yet. Or the file data extends beyond a certain limit. This can make it hard for that page or website to load.

Hence, DNS cache flush comes into play here. All in all, it gets rid of all the old information so Windows can get the new information, which will resolve the above mentioned issues.

This guide shows you how to How to Flush DNS Windows 10 / 11 (Clear Windows DNS Cache).

What is DNS Cache

When you go to a website by typing in its domain name, like, your browser goes to an internet based DNS server to find out the website’s IP address. Then you are taken to that website.

Well, Windows expedites this process by using a temporary file called the DNS cache. It stores important information about how domain names are resolved. 

In turn, this helps your internet connection work faster and better. In normal situations, this cache lets you get to your Internet destination faster by skipping the step of sending a request to an online DNS server.

Why Should You Flush the DNS Cache

Above all, DNS caching works very well to improve browsing speed and efficiency.  But it is not without its cons.

For example, over time, the cache can become contaminated with inaccurate information, thereby slowing your network connection.

Windows first gets information from the cache, finds that it’s broken, and then sends a request to a DNS server. This wastes a lot of time and slows down the network.

Sometimes the IP address of a site may change. If the DNS Resolver Cache has the old IP address record, it may result in your computer not being able to reach the site. Cached data can also become corrupt.

Another case is when the IP address for a website changes. If the DNS Resolver Cache has an outdated IP address record, your computer may be unable to visit the site. Data that has been cached can potentially become corrupt.

When you flush the DNS cache, all of the stored (cached) information is thrown away. This forces the computer to look for new, relevant data instead of sending up old, outdated data.

This can not only solve the connectivity issues but can also be a great help in boosting browsing speed, which has faltered due to DNS issues.
