How to DNS Flush Windows 11: A Step-by-Step Guide for Beginners

How to DNS Flush Windows 11

Flushing your DNS in Windows 11 is a handy trick that clears the DNS cache, which can resolve internet connectivity issues or website loading problems. This process is quick and straightforward: just open Command Prompt as an administrator, type in a specific command, and hit Enter. Boom! Your DNS is flushed.

Step-by-Step Tutorial: How to DNS Flush Windows 11

Flushing the DNS cache will clear out any incorrect or outdated DNS entries, allowing your computer to communicate better with websites. Follow these steps to perform a DNS flush in Windows 11.

Step 1: Open Command Prompt as Administrator

To do this, type "cmd" in the search bar, right-click on the Command Prompt app, and select "Run as administrator."

Running Command Prompt as an administrator is crucial because it grants the necessary permissions to execute the DNS flush command. Without administrative rights, you won’t be able to modify system settings.

Step 2: Type the DNS Flush Command

In the Command Prompt window, type the following command: ipconfig /flushdns.

This command tells your system to clear the DNS resolver cache. It’s like hitting the refresh button on your DNS settings.

Step 3: Hit Enter

Press the Enter key to execute the command.

After hitting Enter, you should see a message saying, "Successfully flushed the DNS Resolver Cache." This confirms that the task was completed.

Step 4: Close Command Prompt

Simply close the Command Prompt window by clicking the ‘X’ at the top right corner or typing exit and hitting Enter.

Closing the Command Prompt window is a small but necessary final step. It ensures that all commands are properly executed and the window doesn’t consume unnecessary system resources.

Once you’ve completed these steps, your DNS cache is cleared. This may resolve issues like slow website loading or connection problems.
