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.
- Open the start menu.
- Search for "cmd" and press 'Enter'.
- When the command prompt opens type the following three commands. Press 'Enter' after each new line:
ipconfig /flushdns
ipconfig /release
ipconfig /renew
- Close this command prompt window.
The exact command required to flush your DNS cache on a Mac varies depending on your version of OS.
- Open terminal - Applications > Utilities > Terminal, or Spotlight search 'Terminal'
- Select your OS from the list below and enter the Terminal command
- Save and Close Terminal
