How to flush DNS cache


The DNS (Domain Name System) cache is a temporary database that contains records of all your recent visits to websites (such as "RuneScape.com"). 

Erasing the DNS cache will remove any invalid records and allow your computer to find the correct address the next time you try connecting to the website or the game.

        ipconfig /flushdns        
        ipconfig /release
        ipconfig /renew
