In a world where cyber threats are becoming more sophisticated, setting up a Private DNS (Domain Name System) is one of the most effective ways to improve your internet security. By default, your Internet Service Provider (ISP) handles your DNS requests, but these may not always be secure or private. In this guide, we’ll walk you through why you should consider a private DNS and how to set it up for maximum online safety.

1. What Is a DNS and Why Does It Matter?
The DNS acts as the phonebook of the internet, converting human-readable domain names like www.example.com into IP addresses that computers can understand. However, traditional DNS servers used by ISPs may log your browsing activities, subject you to unwanted ads, or even expose you to malware.
Why Use a Private DNS?
A private DNS ensures that your internet browsing is more secure, private, and efficient. When you use a public or private DNS service, you’re protecting your data from ISP logging, tracking, and third-party interference. Plus, it can help improve website loading speeds and block malicious sites.
