How to Clear the Windows DNS Cache

The Windows DNS Resolver will cache DNS lookups on your computer for the Time-To-Live period (TTL).  If you change your DNS, there will be a lag, causing the DNS resolver to continue using the old IP address, before it resolves the new IP.

You can force a change by entering a PowerShell or Command window, as Administrator.

  • Launch the shell using CTRL-SHIFT-ENTER.  This will enter Adminsitrator mode.
  • Enter the following command:

> ipconfig /flushdns

 

dns1

That’s it.
