How to Clear Your DNS Cache

Whenever a domain’s DNS settings are changed, it may take time for those changes to fully propagate across the Internet. Even then, the Internet Service Provider you use for Internet access may have the old DNS information cached. Or, your router may have it cached and it needs to be cleared out before you can make a fresh request for the domain.

To clear DNS cache on your computer, please follow these instructions. This may not solve all DNS caching issues, but the vast majority of caching issues can be resolved by following these steps:

Windows® XP, 2000, or Vista®

  1.     Open the Start menu.
  2.     Go to Run. If you do not see the Run command in Vista, search for “run” in the Search bar.
  3.     In the Run text box, type: ipconfig /flushdns
  4.     Press Enter or Return, and your cache will be flushed.

MacOS®

  1.     Go to Applications.
  2.     Go to Utilities.
  3.     Open the Terminal application.
  4.     Type: dscacheutil -flushcache
  5.     Press Enter or Return, and your cache will be flushed.
