How to Flush DNS Cache (Using Windows)?
Posted by Louie Wong on 7 February 2017 11:00 pm

Most computers that are connected to the internet automatically cache the hostname of the websites you have visited to make reloading the pages faster than if there was no cache. If the IP address of a website changes before your cache updates, you may not be able to load the webpage. If you are running into a lot of "Page Not Found" errors and you know you're connected to the internet, try flushing your DNS cache to have your computer request new information.

    • Step 1

      Open the command prompt. The command to flush DNS needs to be entered in the command prompt. Accessing the command prompt is slightly different depending on which version of Windows you are running:



      • Windows 8 - Press the Windows key + X and select "Command Prompt (Administrator)"
      • Windows 7/Vista - Click the Start menu and enter "cmd" into the Search field. Right click on Command Prompt and select "Run As Administrator".
      • Windows XP - Click on the Start menu and then click Run. Enter "cmd" into the Run field and press Enter.

 

  • Step 2

    Use the DNS flush command. Type ipconfig /flushdns and press Enter.



    A message will appear stating "Windows IP configuration successfully flushed the DNS Resolver Cache".



  • Step 3

    Exit the command prompt. Type exit and press Enter. This will close the command prompt.
