Possible disadvantages of AdGuard DNS

• Limited Customization
  While it provides effective ad blocking and security features, users have limited ability to customize which domains are blocked or allowed.
• Potential False Positives
  Some legitimate websites may mistakenly be blocked, disrupting access to desired content.
• Dependency on External Service
  Using a DNS service like AdGuard DNS means reliance on an external provider, which could be a point of concern if the service experiences outages or performance issues.
• Limited Logging and Analytics
  While designed to enhance privacy, this limitation might not be suitable for users who desire detailed analytics or logging of DNS queries.
• No Advanced Features
  AdGuard DNS lacks some advanced features available in other DNS services, such as DNS over HTTPS (DoH) or DNS over TLS (DoT) for more secure DNS traffic.

• Possible Geolocation Issues
  Using a global DNS resolver like Quad9 can sometimes lead to geolocation issues, where content or services are delivered based on server location rather than user location.
