How to fix DNS server not responding and how to change DNS server address?

When facing the error message "DNS server not responding," it can be frustrating and hinder your ability to access websites. This issue usually occurs when the default DNS server provided by your Internet Service Provider (ISP) is not responding or experiencing delays. Changing the DNS server address is a common and effective solution to fix this problem. In this article, we will explore how to change the DNS server address on various devices and operating systems to resolve the "DNS server not responding" issue, offering clear, step-by-step instructions to ensure you can regain smooth internet access.

Understanding the "DNS Server Not Responding" Issue

Before diving into solutions, it’s essential to understand what DNS (Domain Name System) is and why its failure can disrupt your internet connection. DNS is a system that translates domain names (like "www.example.com") into IP addresses that computers use to locate each other on the internet. When a DNS server fails to respond, it means that your computer cannot resolve the website address into an IP address, thus preventing you from accessing websites.

The issue can arise due to various reasons, including server outages, incorrect network settings, or conflicts with security software. While some DNS issues are temporary and related to your ISP's server, others may require intervention on your end, such as changing the DNS server address to a more reliable one.

Why Change DNS Server Address?

Changing your DNS server can resolve several problems and enhance your internet experience in the following ways:

1. Improved Speed: Some DNS servers are faster than others, and by switching to a more efficient one, you can reduce the time it takes for websites to load.

2. Enhanced Security: Certain DNS providers offer additional security features like blocking malicious websites, helping to protect you from phishing attacks and other online threats.

3. Bypassing Geographical Restrictions: Some DNS servers may allow you to access content that is otherwise restricted based on your geographical location.

4. More Stability: If your ISP’s DNS server is often down or unreliable, switching to a public DNS service can provide a more stable connection.
