Flush DNS cache

Game Versions:

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. 



  1. Open the start menu.
  2. Search for "cmd" and press 'Enter'.
  3. When the command prompt opens type the following three commands. Press 'Enter' after each new line:      
        ipconfig /flushdns        
    ipconfig /release
    ipconfig /renew
  1. Close this command prompt window.



The exact command required to flush your DNS cache on a Mac varies depending on your version of OS. 

  1. Open terminal -  Applications > Utilities > Terminal, or Spotlight search 'Terminal' 
  2. Select your OS from the list below and enter the Terminal command
  3. Save and Close Terminal 
OS Terminal command
OS X Yosemite v10.10.4 to macOS 10.15 Catalina
sudo killall -HUP mDNSResponder
OS X Yosemite v10.10 to v10.10.3
sudo discoveryutil mdnsflushcache
macOS 11 Big Sur
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
macOS X 10.6 Snow Leopard
sudo dscacheutil -flushcache

You won't see a success message, even if the command has been entered correctly.
