Flushing your DNS cache on Windows 10 is a simple process that can help resolve internet connectivity issues. By following a few straightforward steps, you can clear the stored DNS data and force your computer to fetch new information from DNS servers. This can help if you’re experiencing problems like websites not loading properly or outdated website information.
Step by Step Tutorial on How to Flush DNS on Windows 10
Flushing your DNS cache will clear out any corrupt or outdated entries, ensuring your computer fetches fresh DNS information. This process involves using the Command Prompt, a built-in Windows tool.
Step 1: Open the Command Prompt
Press the Windows key, type "cmd," and hit Enter.
By doing this, you’ll open the Command Prompt, which is a command-line interface that lets you execute commands directly.
Step 2: Run as Administrator
Right-click on the Command Prompt icon and select "Run as administrator."
Running as an administrator is crucial because it gives you the necessary permissions to make system-level changes, like flushing the DNS cache.
Step 3: Enter the Flush DNS Command
Type ipconfig /flushdns and press Enter.
This command instructs your computer to clear the DNS cache. If successful, you’ll see a message confirming that the DNS Resolver Cache was flushed.
Step 4: Close the Command Prompt
Type exit and press Enter or simply close the Command Prompt window.
Closing the Command Prompt ensures that no additional commands are accidentally entered, and it completes the process.
After completing these steps, your computer will have a fresh DNS cache. This should help resolve any connectivity issues related to old or corrupt DNS data.
