Do you know how to reset or flush DNS (Domain Name System) cache? If not, learn it today! Why? Because flushing DNS cache might help in solving various web browsing or network related problems. The DNS Resolver Cache stores domain name DNS addresses recently used on your computer. This cache reduces DNS network traffic and speeds up name resolution process. So, web sites that you have already visited at least once will open quickly in your browser.
Did you ever experienced problems in accessing certain domain names while browsing the Internet? Or did your web browser failed to open your own web site? In such a situation, clearing your DNS cache might help. Flushing DNS resolver cache removes all cached DNS entire and resets the DNS client resolver cache in you computer.

This simple action actually solves problems like “unable to open site” or “problem loading site”. To solve the above mentioned problems, you must try this first.
