How to Flush DNS on Windows 10

This Itechguide teaches you how to flush DNS Windows 10. The guide covers steps for 2 methods to flush DNS Windows 10 – CMD and PowerShell.

Option 1: Flush DNS with CMD

• Type cmd in the search box. Then, from the search results, click Command Prompt.

• On command prompt, type the command below and press enter key on your keyboard.

ipconfig /flushdns

• The command will return “Successfully flushed the DNS Resolver Cache.” – confirming that the command was successful.

• To display the DNS client resolver cache, type this command and press enter.

ipconfig /displaydns

• The last command will take a while to run – how long it takes to return a result depends the number of entries on the cache.

• If you run the ipconfig /flushdns command and immediately run ipconfig /displaydns, the last command will NOT display any information – confirming that the DNS cache was cleared by the first command.

Option 2: Flush DNS with PowerShell

• Search powershell and open Windows PowerShell. Then, click Windows PowerShell.

• If you wish to display the current DNS cache, on the powershell command prompt, type this command and press the enter key on your keyboard.

Get-DnsClientCache

• The command will display a list of all the DNS entries in the cache.

• Then, to flush the DNS cache, type this command. Then, press the enter key.

Clear-DnsClientCache

• The command runs very quickly and returns to the PowerShell prompt. It will appear that nothing happened.

• To confirm that the DNS cache was flushed, run these two commands in quick succession…

Clear-DnsClientCache
Get-DnsClientCache

• If the DNS cache was cleared successfully, the second command will NOT return any result. See the image below.

• After some seconds, if you run the Get-DnsClientCache command, it will display results. This is because the PC would have updated its DNS resolver cache.
