DNS Server Not Responding: Troubleshooting Guide

Are you experiencing problems with your internet connection? The "DNS server not responding" error can be a common and annoying problem. In this guide, we will examine the causes and solutions of this error in detail.

What is a DNS Server and How Does It Work?

DNS (Domain Name System) is a system that translates domain names on the internet into IP addresses. For example, when you type "www.google.com" into your browser, DNS servers convert this domain name into an IP address and direct you to the correct website. A DNS server works like the internet's telephone book; converts domain names into numeric IP addresses that computers can understand.

Common Causes of DNS Server Not Responding Error

When you encounter this error, there could be several causes:

• Internet Connection Problems: Interruptions in modem or router connections can prevent access to DNS servers.
• Incorrect DNS Settings: The DNS settings on your computer or modem may be configured incorrectly.
• Firewall and Firewall Settings: Firewall or antivirus programs can block DNS traffic.
• DNS Server Problems: The DNS server you are using may be temporarily unavailable.

How to Fix DNS Server Not Responding?

You can follow the steps below to fix this error:

1. Check Internet Connection: Restart your modem and router and make sure your internet connection is working properly.
2. Check DNS Settings: Check the DNS server addresses in your computer or device's network settings and enter the correct addresses if necessary.
3. Temporarily Disable Firewall and Antivirus Programs: Make sure your security software is not blocking DNS traffic.
4. Clear DNS Cache Flush: Flush your DNS cache using the "ipconfig /flushdns" command in the command prompt.

Solve DNS Problems with Modem and Router Settings

Some changes you can make to your modem and router settings can help you solve DNS problems:

• Restart the Modem and Router: You can solve temporary connection problems by restarting your devices.
• Enter DNS Settings Manually: Enter the settings of your modem or router and manually specify the DNS server addresses. For example, Google DNS servers (8.8.8.8 and 8.8.4.4) can be used.
• Firmware Updates: You can fix DNS issues by updating the firmware of your modem or router.

Tips to Troubleshoot Using Alternative DNS Servers

• Google DNS: 8.8.8.8 and 8.8.4.4
• Cloudflare DNS: 1.1.1.1 and 1.0.0.1
• OpenDNS: 208.67.222.222 and 208.67.220.220
