how to flush dns windows 10
Flushing the DNS cache on Windows 10 is a simple process that helps resolve networking issues by clearing outdated or corrupted DNS records. This can boost browsing speed and fix issues like website not found errors. To do this, you’ll need to use the Command Prompt. Follow these steps, and you’ll have a refreshed DNS cache in no time.
Step by Step Tutorial on How to Flush DNS Windows 10
In this tutorial, we’ll walk through the process of flushing the DNS cache on a Windows 10 system. By the end of these steps, you’ll know how to clear the DNS cache and improve your internet connectivity.
Step 1: Open the Command Prompt as an Administrator
Press the Windows key, type "cmd," then right-click on "Command Prompt" and select "Run as administrator."
Opening the Command Prompt as an administrator gives you the necessary permissions to execute the commands needed to flush the DNS cache. If you don’t run it as an administrator, the command may fail due to lack of permissions.
Step 2: Confirm the User Account Control (UAC) Prompt
Click "Yes" when the User Account Control (UAC) prompt appears to grant administrative privileges.
The UAC prompt ensures that you have the authority to make significant changes to the system. It’s a safety feature to prevent unauthorized changes by malicious software.
Step 3: Type the Command to Flush DNS Cache
In the Command Prompt window, type ipconfig /flushdns and press Enter.
This command instructs Windows to clear the DNS resolver cache, which stores the IP addresses of frequently visited websites. Flushing it helps in resolving connectivity issues.
Step 4: Wait for the Confirmation Message
After pressing Enter, wait for the message "Successfully flushed the DNS Resolver Cache."
This message confirms that the DNS cache has been successfully cleared. If you see an error message instead, double-check that you have administrative privileges and typed the command correctly.
Step 5: Close the Command Prompt
Type exit and press Enter to close the Command Prompt window.
Closing the Command Prompt ensures that no further changes are made inadvertently. Your DNS cache is now refreshed, and you can proceed with your internet activities.
After completing these steps, you should notice an improvement in your browsing speed and a reduction in connectivity issues. The DNS cache will begin to repopulate with fresh data as you visit websites.
