What is the Difference Between Public and Private AdGuard DNS?

servers room

The Domain Name System (DNS) is the unsung hero of the internet, quietly translating human-friendly domain names into IP addresses that computers understand. One popular DNS solution that has gained attention is AdGuard DNS. AdGuard DNS offers both public and private options, each with its unique features and benefits. In this article, we will explore the differences between public and private AdGuard DNS and help you decide which one suits your needs. We’ll also address a common question: Is private DNS similar to a Virtual Private Network (VPN)?

Public AdGuard DNS

Public AdGuard DNS is a publicly accessible DNS service provided by organizations or companies, offering a secure and privacy-focused alternative to the default DNS servers provided by internet service providers (ISPs). It comes with several advantages, including faster browsing by reducing the time to resolve domain names, enhanced security through the blocking of malicious websites, and a higher level of privacy compared to many ISPs, although it’s not entirely private and may log some data. However, users should consider that speed and reliability may vary depending on their location and network conditions, and while it’s easy to set up, it might not offer the customization options required for specific purposes.

Private AdGuard DNS

Private AdGuard DNS, typically utilized within organizations, businesses, or by individuals seeking heightened control over their DNS settings, provides a customized and managed DNS infrastructure. This service comes with various benefits, including enhanced privacy by affording complete control over user data, customization options for tailored needs such as content filtering or access control, and seamless integration into network infrastructure for robust DNS resolution control. However, it’s essential to consider that while private AdGuard DNS offers improved security and privacy compared to its public counterpart, it places the responsibility of maintenance on the user, potentially requiring a steeper learning curve for customization and configuration

Key Differences

When deciding between public and private AdGuard DNS, it’s crucial to understand the key distinctions between the two. These differences encompass ownership, privacy, customization, use cases, and various other factors that can significantly impact your online experience and security. Let’s delve deeper into these differentiating features to help you make an informed choice.

  • Ownership and Control: Public AdGuard DNS is managed by AdGuard and open to all, while private AdGuard DNS is controlled and managed by an organization or individual.
  • Privacy and Security: Public DNS may have privacy concerns, while private DNS offers enhanced privacy and security.
  • Customization and Configuration: Public DNS provides limited customization options, while private DNS is highly customizable.
  • Compliance: Private AdGuard DNS can be configured to comply with specific regulatory requirements and industry standards, which may be crucial for businesses operating in regulated sectors.
  • Network Integration: Private AdGuard DNS seamlessly integrates with the organization’s existing network infrastructure, enabling centralized management and control.
  • Cost Considerations: Public AdGuard DNS is typically free for personal use, while private AdGuard DNS may involve additional costs for setup, maintenance, and support.
  • Support and Documentation: Public AdGuard DNS often comes with limited support options and documentation, while private AdGuard DNS users may benefit from dedicated support and extensive documentation for their customized setups.

Is Private DNS Like VPN?

Private DNS and Virtual Private Networks (VPNs) have distinct purposes but can complement each other effectively. Private DNS focuses on enhancing control over DNS resolution, ensuring security and customization. In contrast, VPNs prioritize encrypting your internet traffic, thereby offering privacy and security by routing your data through remote servers. Combining both private DNS and a VPN can create a comprehensive solution for enhancing privacy and security online.


In the public vs. private AdGuard DNS debate, the choice depends on your specific needs. Public AdGuard DNS offers enhanced speed and privacy, making it a good choice for individuals. Private AdGuard DNS, on the other hand, is tailor-made for businesses and tech-savvy users who seek granular control over DNS settings. Remember to consider your privacy requirements, customization needs, and use case when making your decision.

And while private DNS and VPNs are distinct technologies, they can complement each other in securing your online activities. Ultimately, the importance of DNS in online security and performance cannot be overstated, making it worth the effort to choose the DNS solution that aligns with your priorities
