Many computer operating systems use caching to store DNS lookup results. Normally this is not a problem, and accelerates network performance.

How Do I Flush My DNS Cache on Windows?


The following guide will walk you through flushing your DNS Cache. Every time you venture onto the Internet, DNS resolutions are being made and your computer stores many of them. Caching these resolutions can speed up your web activities because your computer no longer has to ask another computer where something is located.

Eventually, there will come a time when a bad entry is stored. There are generally two ways to remove these entries. First is to allow 24 hours to pass. During this time your computer will seek out and make the necessary DNS updates. Second is to flush your DNS cache.

  1. The first step to flushing your DNS is to open your “Windows Command” prompt.
  2. Click “Start” and type the word “Command” in the Start search field.
  3. Right-click the command prompt icon and select the option to “Run as Administrator”.
  4. In the open prompt, type “ipconfig /flushdns” (without the quotes).
    You should receive a message of your success as confirmation when the cache is cleared.

Flushing the cache removes all the information stored within the cache, forcing the computer to find new DNS information.
