Flush DNS Cache in Windows 11 (2021)
If you are experiencing connectivity issues even after deleting the temporary files and clearing the app cache on your Windows 11 computer, the underlying problem might be with the way the network is configured. To correct it, you will need to flush the DNS resolver settings in your computer. Best practice dictates that you also restart your modem and router to clear out all cached DNS settings. With that said, let’s get started:
What is DNS Cache and Why Should You Care?
DNS cache is a file that includes the hostnames and IP addresses of the websites you have visited on your computer. As the name suggests, it caches the webpage, which results in the site loading faster the next time you open it. The caches are located in the client computer, as well as in the servers of the ISP (Internet Service Provider).
While most systems connected to the internet automatically update the cache and hostname, problems arise when the IP address of a webpage changes before the update. That’s when you can have connectivity issues, with the page failing to load in your browser. Flushing the DNS cache removes all the stored (cached) information, which forces the computer to retrieve relevant new data rather than serving up old and obsolete data.
