Should Private DNS Be Off or Automatic Making the Right Choice for Security

With the growing concerns around privacy and security, many Android users are wondering if they should turn off Private DNS or keep it on Automatic. Private DNS is a feature that was introduced in Android 9 Pie that encrypts DNS requests to prevent eavesdropping and spoofing. 

While it can enhance privacy by hiding your browsing history from your ISP or public WiFi, some users argue it is an unnecessary battery drain. In this blog post, we’ll compare turning Private DNS off versus leaving it on Automatic. 

We’ll look at how each option impacts privacy, security, battery life, connection speeds, and more. By the end, you’ll know whether you should disable Private DNS or keep it enabled for maximum protection. With privacy concerns at an all-time high, understanding the Private DNS settings on Android is critical.

Understanding DNS: The Internet’s Address Book

Before we dive into the Private DNS settings, it’s essential to grasp the fundamental role of DNS in the online world. 

DNS serves as the internet’s address book, translating domain names like into the corresponding IP addresses, which are necessary for your device to locate and connect to the intended website’s server. It’s a crucial process that happens behind the scenes every time you visit a website.

The Importance of Private DNS

Private DNS, as the name suggests, offers a more personalized and secure DNS resolution. It is an alternative to using the default DNS servers provided by your Internet Service Provider (ISP) or other third-party DNS providers. Here are some reasons why you should consider the importance of Private DNS:

1. Enhanced Privacy

By using Private DNS, you can protect your online activities from prying eyes. It prevents your ISP from tracking your browsing history and allows you to maintain a higher level of anonymity on the internet.

2. Reduced Risk of DNS Hijacking

Private DNS reduces the risk of falling victim to DNS hijacking, a malicious technique used by cybercriminals to redirect your traffic to malicious websites. This extra layer of security is vital in today’s threat landscape.

3. Faster Browsing

Private DNS servers are often optimized for speed, which can lead to faster website loading times and a smoother online experience. This improvement in performance can be especially noticeable when you’re accessing international websites.

4. Customization

Private DNS allows you to have more control over your DNS resolution. You can configure it to block specific domains or content categories, enhancing your online experience and security.

When to Keep Private DNS Off

While Private DNS offers several advantages, there are situations where keeping it off might be a better choice:

1. Compatibility Issues

Some devices and applications may not work correctly with Private DNS, leading to connectivity problems. In such cases, you might need to switch back to your ISP’s DNS servers temporarily.

2. Limited Provider Options

Depending on your region and network setup, you might have limited options for Private DNS providers. If the available choices do not meet your requirements, using your ISP’s DNS might be the more practical option.

3. Technological Constraints

In some cases, older devices or network configurations may not support Private DNS. In such situations, turning it on might not be feasible.

Making the Right Choice

The decision to keep Private DNS off or automatic should be based on your specific needs and circumstances. Here are some key factors to consider when making this choice:

1. Security Requirements

If your online activities require a high level of security and privacy, leaving Private DNS automatic is the better choice. It provides added protection against threats and data leaks.

2. Device Compatibility

Consider the devices you use regularly. Ensure that they are compatible with Private DNS to avoid any connectivity issues.

3. Network Configuration

Evaluate your network setup and your ISP’s DNS performance. If your Private DNS provider offers better speed and security, the choice becomes more apparent.

In Conclusion

In the end, the choice between turning Private DNS off or leaving it on Automatic comes down to your personal preferences around privacy versus convenience. If privacy is your top concern and you want to obscure your DNS information from third parties, then leaving Private DNS on Automatic is the best way to go. 

However, disabling it can provide minor improvements to battery life, speed, and connectivity issues in certain situations. For most users who prioritize privacy and security, the minimal trade-offs are worth it to keep Private DNS enabled. 

Unless you are experiencing significant technical issues that may be related to Private DNS, it’s recommended to leave it on Automatic for optimal privacy protection. Just be aware that it doesn’t hide all online activity, so additional steps like VPNs may be necessary for full anonymity.
