Whenever you visit a website using it’s domain name (i.e. microsoft.com), your browser is directed to a DNS server where it learns the IP address of that website. You are then directed to that website. A record of the IP address that domain name points to is created within Windows so that if you visit that same website again, the information is accessed quicker. These records that get created make up the DNS Resolver Cache.
Flushing the DNS resolver cache can help resolve DNS related problems in Microsoft Windows 10. Issues would include website not found errors or not being able to view certain web pages that have changed.
Please follow below steps to clear the DNS cache.
1. Open the command prompt as "Administrator"
2. Type ipconfig /flushdns then press “Enter“
