How to Clear or Flush DNS on Your Windows 10

Published

A DNS server is what turns common domain names, such as howtogeek.com, into the IP addresses that computers use to interact with one another on the internet. Your computer will query a DNS server located elsewhere on the internet in order to obtain the matching numerical IP address whenever an application on your computer attempts to connect to a domain name such as google.com or facebook.com. Windows 10 will save a copy of the information it obtains from DNS servers locally on your own computer so that it can access it more quickly. The cache for the DNS is what this is termed.

If there is an issue with the DNS cache on your own computer, you may have problems connecting to the internet. If you have already attempted the common troubleshooting steps, such as clearing the cache and cookies from your browser, then you should try flushing the DNS settings in Windows 10. In the following post, we will walk you through the process of clearing and flushing DNS on Windows 10. So let’s get started:
