How do I flush my DNS cache on Windows?

Why would I need to do this?

The DNS (Domain Name System) cache contains all the information needed to convert a domain name (such as "") into it's IP address which is used to request information from the server. If you are having connectivity problems (disconnections or lag), clearing out this cache (called 'Flushing') can help resolve the issue or improve your connection.

How would I do this?

  1. Open the start menu.
  2. In this menu, 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.
