What Is a DNS Server and How Do I Fix It?

A DNS (Domain Name System) server is responsible for translating domain names into IP addresses. When you enter a website URL in your browser, the DNS server helps your device locate the correct IP address associated with that domain name. Without a functioning DNS server, your device won’t be able to connect to websites by their names.

Why Do You Need to Fix Your DNS Server?

If you are experiencing issues accessing websites or if your internet connection is slow, there’s a chance that your DNS server could be the culprit. In such cases, fixing your DNS server can help resolve these connectivity issues and improve your browsing experience.

How to Fix Your DNS Server:

If you’re encountering problems with your DNS server, here are some troubleshooting steps you can follow:

1. Restart Your Router:

This is often the simplest and most effective solution.

Turn off your router, wait for a few seconds, and then turn it back on. This will refresh the router’s settings and may resolve any temporary issues with the DNS server.

2. Use an Alternative Public DNS Server:

If restarting your router doesn’t work, you can try using an alternative public DNS server such as Google Public DNS or OpenDNS. These servers offer fast and reliable connections and can help bypass any issues with your default DNS server.

  • To use Google Public DNS:
    • Go to your network settings.
    • Select “DNS Settings” or “Network Settings”.
    • Add the following IP addresses as primary and secondary DNS servers:
      • Primary DNS: 8.8.8
      • Secondary DNS: 8.4.4
  • To use OpenDNS:
    • Go to your network settings.
    • Add the following IP addresses as primary and secondary DNS servers:
      • Primary DNS:
      • Secondary DNS: 208.220.220

3. Flush Your DNS Cache:

If you’re still experiencing issues, clearing your DNS cache can help resolve any lingering problems. To flush your DNS cache, follow these steps:

  • Open the Command Prompt (Windows) or Terminal (Mac).
  • Type the following command and press Enter:
  • ipconfig /flushdns

4. Contact Your Internet Service Provider (ISP):

If none of the above solutions work, it’s possible that there may be an issue with your ISP’s DNS server. In this case, contacting your ISP’s customer support can help resolve the problem.

By following these steps, you should be able to fix most common DNS server issues and regain access to websites without any trouble.

In Conclusion

A functioning DNS server is essential for accessing websites by their domain names rather than their IP addresses. If you encounter any issues with your DNS server, try restarting your router, using an alternative public DNS server, flushing your DNS cache, or contacting your ISP for assistance. These troubleshooting steps should help you fix the problem and get back to browsing the web smoothly.
