But what are the best free and public DNS servers of 2023? Keep reading to learn more, and start opting for one today!

What Are DNS Servers?

As briefly mentioned before, a DNS server is an essential part of the Internet, responsible for turning domains into IP addresses.

They translate a friendly domain name (like maketecheasier.com) into a string of numbers required for your device to communicate with the site.

Think of DNS servers as the phone book for the Internet; it allows users to access websites using names rather than long IP addresses.

Accordingly, when you look up a domain on your browser, the DNS servers identify the corresponding IP address and redirect the user.

As a result, without DNS servers, you’d have to memorize giant numbers, making it quite hard to surf the web and access your favorite websites.

Your Internet Service Provider (ISP) automatically assigns DNS servers when your device (router, computer, etc.) connects to the Internet.

However, many of the assigned DNS servers are laggy, leading to a slower overall browsing experience and a world of agony.

Why Use Different DNS Servers?

DNS servers come in handy in a handful of circumstances, and you can conveniently decide when to opt for one by studying such factors.

Here’s why you should use a different DNS server:

  • Faulty DNS servers: If you have internet connectivity issues due to an incorrect DNS setup, you can conveniently replace the servers with a fast and secure public DNS to resolve the problems. Accordingly, you could test your suspicion by typing a website’s IP address into your browser. If you can reach it with the IP address but not the domain name, then the DNS server is having issues.
  • Better performance: When you purchase an Internet subscription, your provider assigns you a default DNS server. However, many complain that the ISP-provided DNS servers are laggy, leading to a slower overall browsing experience. Accordingly, you can overcome the troubles by changing to a faster DNS server.
  • Prevent activity logs: Many websites and third-party apps keep constant records of your web activity and sell them to advertising agencies for a benefit. Accordingly, if you value your privacy and wish to prevent such services from logging your actions, you can opt for a DNS provider exclusively designed to circumvent these scenarios.

Although changing your DNS servers doesn’t fix all your internet issues, they are for sure worth a shot!
