Flushing the DNS cache in Windows 11 is a straightforward task that can help resolve network-related issues and ensure you’re accessing the most up-to-date versions of websites. The process involves using the Command Prompt to clear the DNS cache, which can help fix problems like slow internet browsing or website not loading properly.
How to Flush DNS on Windows 11
Flushing the DNS cache on Windows 11 will erase the stored DNS information, forcing your computer to fetch new details from the DNS server, which can resolve connectivity issues and improve browsing speed.
Step 1: Open the Start Menu
Click the Start button on the bottom left corner of your screen.
The Start Menu is the gateway to all your programs and system settings. By clicking it, you can access the search bar, which is essential for locating the Command Prompt.
Step 2: Search for “Command Prompt”
Type “cmd” in the search bar.
Searching for “cmd” will quickly bring up the Command Prompt application. Ensure you run it with administrative privileges to execute the necessary commands.
Step 3: Run Command Prompt as Administrator
Right-click on “Command Prompt” and select “Run as administrator.”
Running Command Prompt as an administrator gives you the required permissions to flush the DNS cache. Without this, you might receive an error when attempting the flush.
Step 4: Confirm the UAC Prompt
Click “Yes” when the User Account Control (UAC) prompt appears.
The UAC prompt is a security measure to prevent unauthorized changes to your system. Confirming it allows you to proceed with administrative tasks.
Step 5: Enter the DNS Flush Command
Type ipconfig /flushdns and press Enter.
This command tells your system to clear the current DNS cache. You should see a confirmation message indicating the successful completion of the task.
Once you’ve completed these steps, your DNS cache will be cleared, and your system will start fetching fresh DNS data from the server.

- After flushing the DNS, restart your browser to ensure it uses the updated cache.
