How to Flush DNS Cache in Windows

The Domain Name System (DNS) is a crucial component of the internet, as it translates human-readable domain names like "google.com" into numerical IP addresses that computers can understand. Over time, your DNS cache can become cluttered with outdated or incorrect entries, potentially causing connectivity issues or slow performance. Flushing the DNS cache helps clear these temporary files and improve internet stability.
Methods to Flush DNS Cache:
Command Prompt:
- Open the Start menu and type "Command Prompt".
- Right-click the "Command Prompt" option and select "Run as Administrator".
- In the command prompt window, type "ipconfig /flushdns" (without quotes) and press Enter.
PowerShell:
- Open the Start menu, type "PowerShell," and select "Run as Administrator."
- In the PowerShell window, type "Clear-DnsClientCache" (without quotes) and press Enter.
Restart your PC:
Restarting your computer also clears the DNS cache, making it a simple and effective method.
Benefits of Flushing DNS Cache:
Flushing your DNS cache offers several benefits:
- Improved internet connectivity by clearing outdated DNS entries.
- Potential increase in browsing speed by reducing latency.
- Resolution of connectivity issues caused by DNS errors.
Conclusion
Flushing the DNS cache is a quick and easy process that can improve your internet experience. Use the methods outlined above when experiencing connectivity issues or performance slowdowns related to DNS.
