How do I fix DNS server not responding error?

DNS, or Domain Name System, serves as a critical component of the Internet, translating readable domain names to IP addresses. Most of us don't even think about DNS where we conduct everyday online activities such as browsing, emailing, or video conferencing. However, if DNS encounters an error, you'll quickly see the impact.

When a DNS server stops working, you'll see a "DNS server not responding" error message. This error can be frustrating and has the potential to disrupt your day-to-day online activities. This blog post provides you with actionable tips and tricks to get the problem fixed quickly.

Before diving into resolving the issue, let's explore how DNS works and what causes errors.

How Does DNS Work?

When you type in a domain name, your device sends a request to the DNS server to convert it into an IP address. The DNS server then responds with the correct IP address, allowing your device to connect to the website or server requested.

Common DNS Issues

Several reasons cause DNS issues:

1. Router Issues

The router plays a significant role in DNS function, including translating domain names into the IP addresses you need to visit websites. However, unexpected router changes to your router, faulty firmware updates, or incorrect DNS settings can cause DNS server not responding error. In such cases, users find themselves on the receiving end of error.

2. Internet Provider Issues

The Internet Service Provider controls the DNS, and if the internet package's DNS settings are not functioning correctly on the server, it'll be difficult to access the website or speed up online tasks. Even the best internet service provider encounters issues such as a DNS server not responding error, and it's up to users to fix it.

3. Third-Party DNS Tools

Some users choose third-party DNS tools such as Google DNS or OpenDNS to boost network speed, privacy, and security. However, sometimes these tools may not work correctly, leading to DNS server not responding error.

DNS Server Not Responding Error Fixes

Here are five quick and easy fixes to resolve DNS server not responding issues:

1. Restart Router and Modem

Turn off and unplug the router and modem and wait at least 30 seconds before restarting. Reconnect the cables, power on, and launch your browser to see if it loads the website.

2. Change DNS Server Addresses

DNS servers have backup IP addresses in case the primary server fails. Changing DNS server addresses might help to fix the problem.

You can Google "public DNS servers" or use popular DNS servers like Google DNS servers—8.8.8.8 or 8.8.4.4, or OpenDNS servers: 208.67.222.222, 208.67.220.220, and 208.67.222.220.

To set up the DNS server in Windows, follow these simple steps:

• Right-click on the Network icon on your Taskbar and select "Open Network Connections."
• Right-click on your Wi-Fi network and select "Properties."
• Choose "Internet Protocol Version 4(TCP/IPv4)" from the list and select "Properties."
• Now select the "Use the following DNS server addresses" option and enter the desired DNS server address.

3. Remove DNS Cache

DNS cache saves website information on your device for easy re-access instead of searching through hundreds of IP addresses when you want to launch a website. When DNS cache is corrupted, it's no surprise that "DNS server not responding" error is the next message you'll see.

To clear the DNS cache, follow these steps:

• Press the "Windows key + R" > type "cmd" > then press "Enter."
• Type "ipconfig /flushdns" and press "Enter."
• Then restart your system and try loading the website again.

4. Disable Windows Firewall

Sometimes the Windows firewall can interrupt your internet connection. Disabling the Windows firewall is beneficial in troubleshooting DNS server not responding errors. Here's how to do it:

• Click on the "Start" menu > Type "Windows Defender Firewall" > Select "Turn Off Firewall" on both "Public and Private network settings."
