Troubleshooting common issues

If you encounter any problems during this process or receive unexpected results, here are a few common issues and their solutions:

No response from DNS server

If there is no response from the DNS server or if it takes too long to respond, it could indicate a problem with your internet connection. Try restarting your router or contacting your internet service provider (ISP) for assistance.

Incorrect DNS server

If the DNS server displayed is not the one provided by your ISP, it could be caused by misconfigured network settings. To fix this, you can manually set your DNS server to the correct one provided by your ISP or use a public DNS service like Google DNS (8.8.8).

Inconsistent results

If you receive different results when checking the same domain name multiple times, it could be due to caching. DNS records are cached by servers and your computer to improve performance. To get the most up-to-date information, you can flush your DNS cache by typing ‘ipconfig /flushdns’ in the Command Prompt and pressing Enter.


Checking your DNS server is a simple yet effective way to troubleshoot internet connectivity issues. By following the steps outlined in this guide, you can quickly identify any problems and take appropriate action. Remember to consult with your ISP if you encounter persistent issues or need further assistance.
