How Do I Fix a DNS Server Not Responding?

When you encounter a DNS server not responding error, it can be frustrating as it disrupts your internet browsing experience. However, there are several troubleshooting steps you can take to resolve this issue and get back online quickly.

1. Check Your Internet Connection

If you’re unable to access any websites, the first step is to ensure that your internet connection is working correctly.

Make sure that your modem or router is powered on and connected properly. You can also try restarting your devices and see if it resolves the problem.

2. Clear DNS Cache

DNS cache stores information about previously visited websites, and sometimes it can become corrupted or outdated, leading to the DNS server not responding error. To clear the DNS cache:

• Windows:
• Open the Command Prompt by pressing Windows Key + R, type cmd, and press Enter.
• In the Command Prompt, type ipconfig /flushdns and press Enter.
• Mac:
• Open Terminal from the Applications > Utilities folder.
• Type dscacheutil -flushcache and press Enter.

3. Change DNS Server Addresses

If clearing the DNS cache doesn’t resolve the issue, you can try changing your DNS server addresses to alternative ones like Google Public DNS or OpenDNS. Here’s how:

In Windows:

1. Right-click on the network icon in the taskbar and select “Open Network & Internet settings. “
2. Click on “Change adapter options.

   “

3. Right-click on your active network connection and select “Properties. “
4. Scroll down and double-click on “Internet Protocol Version 4 (TCP/IPv4). “
5. Select “Use the following DNS server addresses” and enter the preferred and alternate DNS server addresses.

In Mac:

1. Go to Apple menu > System Preferences > Network.
2. Select your active network connection and click on “Advanced.”
3. Go to the “DNS” tab.
4. Click on the “+” button to add a new DNS server address.
5. Enter the preferred and alternate DNS server addresses.

4. Disable Firewall or Antivirus Temporarily

Sometimes, firewalls or antivirus software can interfere with your DNS settings, causing connectivity issues.

Temporarily disable your firewall or antivirus program and check if the DNS server not responding error persists. Remember to enable them once you’ve identified and resolved the issue.

5. Contact Your ISP

If none of the above solutions work, it’s possible that the problem lies with your Internet Service Provider (ISP).

Contact their customer support for assistance. They may be experiencing technical difficulties or have specific instructions to resolve DNS-related issues for their customers.

In conclusion, a DNS server not responding error can be resolved by checking your internet connection, clearing the DNS cache, changing DNS server addresses, temporarily disabling firewalls or antivirus programs, or contacting your ISP for assistance. By following these troubleshooting steps, you can get your DNS server back up and running smoothly.
