Understanding Private DNS and How to Enable It on Android for Enhanced Privacy
By John Doe/TechExplainer
In today's digital age, nearly everything you do on your desktop, laptop, phone, and tablet begins with a Domain Name System (DNS) query. Essentially, DNS turns domain names (like TechExplainer.com) into an IP address so web browsers and apps know where to get the information you want.
Imagine having to type 93.184.216.34 every time you wanted to visit TechExplainer.com. Fortunately, DNS saves you from this hassle by translating domain names into their corresponding IP addresses automatically. However, there’s a hidden challenge: DNS queries are typically unencrypted, which means they can be intercepted and read by anyone monitoring the network. This is especially concerning when using public networks, such as those in coffee shops and airports.
If you value your privacy, understanding and enabling Private DNS on your Android device is essential. Not only does it help keep your browsing habits hidden, but it also protects you from potential threats. In this article, we delve deeper into the importance of Private DNS, how it works, and the steps to enable it on your Android device.
Why Non-Encrypted DNS Is a Problem
When you connect to a public network, your device's DNS queries are sent in plain text. This means that anyone with the right skills and tools can capture these queries and know exactly what websites you are visiting. This is a significant privacy issue, especially if you are accessing sensitive information or logging into secure systems, such as a company’s Content Management System (CMS).
Consider the scenario where a hacker is on the same public network and intercepts your DNS queries. They can easily see which websites you visit, and in some cases, manipulate your DNS responses to redirect you to malicious sites. This is where Private DNS becomes crucial.
What Is Private DNS?
Private DNS (also known as DNS over TLS) encrypts your DNS queries, protecting them from being read or modified by third parties. When enabled, Private DNS ensures that all DNS queries are encrypted and secured, significantly enhancing your online privacy and security. It’s particularly important for anyone frequently using public Wi-Fi networks.
How to Enable Private DNS on Android
Enabling Private DNS on your Android device is a straightforward process. Here is a step-by-step guide:
Prerequisites
To enable Private DNS, you'll need an Android device running at least Version 9 of the operating system (released in 2018). Most modern Android phones support this feature.
Step 1: Open Network & Internet Settings
Open the Settings app on your Android device. You can do this either from the Notification Shade or the App Drawer. Once in the Settings app, tap on Network & Internet.
Step 2: Enable Private DNS
In the Network & Internet settings, scroll down and tap on Private DNS. On some devices, this option might be located under More Connection Settings.
Step 3: Add a Secure DNS Provider
To use Private DNS, you need the address of a DNS provider that supports DNS over TLS. Here are some recommended providers:
| Provider | Hostname |
|---|---|
| Cloudflare | 1dot1dot1dot1.cloudflare-dns.com |
| Google DNS | dns.google |
| Quad9 | dns.quad9.net |
| Cleanbrowsing DNS | security-filter-dns.cleanbrowsing.org |
| Open DNS | 208.67.222.222 |
| NextDNS | 45.90.28.0 |
| Comodo Secure | 8.26.56.26 |
| OpenNIC | 192.95.54.3 |
For this example, we'll use Cloudflare's DNS because of its speed and added security features. Tap on Private DNS Provider Hostname and enter 1dot1dot1dot1.cloudflare-dns.com. Finally, tap Save.
Step 4: Verify Private DNS Is Working
You can verify that Private DNS is active by opening your web browser and navigating to http://1.1.1.1/help. Look for the setting "Using DNS over TLS (DoT)" and ensure it is set to "Yes." If it is, your DNS queries are now encrypted.
Conclusion
Enabling Private DNS on your Android device is a simple yet effective step to secure your online activities and enhance your privacy. By following this guide, you can protect your DNS queries from unauthorized access and maintain greater control over your digital footprint.
