Which option do you use with "ipconfig" to purge the DNS cache?

 EXPLANATION

Flushing the DNS cache on Windows  is a very easy process. Due to system security permissions, you must ensure that you run the command prompt as an administrator user.

  1. Ensure that you're on the Windows Start Screen.
  2. Simply type cmd and the Windows search bar will appear on the right hand side with search results.
  3. Right click on Command Prompt and click Run as administrator
  4. Type in the command ipconfig /flushdns

Linux

If you are running the nscd Name Service Cache Daemon and wish to flush your DNS cache, then you will need to do the following.
  1. Open up a command terminal (either as root or run step 2 with sudo).
  2. Run the command /etc/init.d/nscd restart
