What Is the Best DNS Server for Linux?


Larry Thompson

Are you a Linux user looking to optimize your DNS server for better performance and security? In this article, we will explore the best DNS servers for Linux and how to choose the right one for your needs.

What is a DNS Server?

A DNS (Domain Name System) server is responsible for translating domain names into IP addresses. Whenever you type a website address into your browser, the DNS server is queried to find the corresponding IP address. This process allows you to access websites by their domain names instead of remembering complex numerical IP addresses.

Why Should You Consider Changing Your DNS Server?

Performance: By default, your ISP assigns you a DNS server. However, it might not be optimized for speed or may be experiencing high traffic, resulting in slower internet browsing.

Changing your DNS server can help improve website loading times and overall browsing experience.

Security: Some DNS servers offer enhanced security features like blocking malicious websites and phishing attempts. By using a secure DNS server, you can protect yourself from potential online threats.

The Best DNS Servers for Linux

1. Google Public DNS

Google Public DNS is one of the most popular and reliable options available.

It offers fast response times and supports both IPv4 and IPv6 addresses. Google Public DNS also includes security features like blocking known malicious domains.

2. Cloudflare DNS

Cloudflare, known for its robust content delivery network (CDN), also provides a free and secure DNS service. Cloudflare’s DNS boasts low latency and high performance due to its global network infrastructure.

3. OpenDNS

OpenDNS is another widely used DNS service that offers fast and reliable performance. It provides additional security features, such as malware and phishing protection, to keep your browsing experience safe.

How to Change Your DNS Server on Linux

Now that you’ve learned about some of the best DNS servers for Linux, let’s discuss how to change your DNS server:

  • Step 1: Open the terminal on your Linux system.
  • Step 2: Edit the /etc/resolv.conf file using a text editor like nano or vim.
  • Step 3: Locate the line that starts with “nameserver“. This line specifies your current DNS server.
  • Step 4: Replace the existing DNS server address with the address of your chosen DNS server (e.g., 8.8.8 for Google Public DNS).
  • Step 5: Save and exit the file.

Note: Keep in mind that manually changing your DNS server settings may require administrative privileges.

In Conclusion

In summary, choosing the right DNS server for your Linux system can significantly improve both performance and security. Consider experimenting with different options like Google Public DNS, Cloudflare DNS, or OpenDNS to find the one that works best for you. Remember to follow the necessary steps to change your DNS server on Linux and enjoy a faster and safer browsing experience!
