Introduction: The Last Unencrypted Link
Even if you use a secure website (HTTPS), your computer still has to ask for the website's IP address. For years, these DNS requests were sent in plain text, meaning anyone on your network could see exactly which sites you were visiting. Private DNS is the technology that finally encrypts this last unencrypted link.
In this guide, we'll explain how Private DNS works and why it's a vital feature for modern smartphones and computers.
How Private DNS Works
Private DNS uses two main technologies: **DoT (DNS over TLS)** and **DoH (DNS over HTTPS)**. Instead of sending your query as a simple message, your computer wraps it in a layer of high-level encryption. This ensures that even your ISP cannot see which domain names you are looking up. All they see is an encrypted connection to your DNS provider.
Why Use It?
- Prevent Censorship: Governments and schools often block websites by filtering DNS requests. Private DNS bypasses these filters because the requests are encrypted and hidden.
- Stop Ad-Tracking: ISPs can't see your browsing habits to build an ad profile on you.
- Security on Public Wi-Fi: Prevents 'Man-in-the-Middle' attacks where hackers try to intercept your DNS queries to send you to fake sites.
Conclusion
Private DNS is a simple toggle in your Android or iOS settings that provides a massive boost to your daily privacy. It’s a must-have for the modern internet. Check your private DNS status here.
