Frequently Asked Questions
Clear answers on performance, differences, and usage.
View All FAQsCan it block all ads?
DNS filtering operates at the domain level, making it ideal for blocking dedicated ad and tracking domains. Ads sharing domains with normal content and certain embedded video ads may not be filtered independently. Actual performance depends on applications, device configuration, and applied rules.
View Filtering PrinciplesWhat is the difference between public and private services?
The public service uses standardized rules, suitable for basic ad blocking and privacy protection. The private service provides query logs, block analytics, and custom rules, catering to users who need personalized filtering and family management. Specific features are subject to plan details.
Learn About Public ServiceIs setup required after purchase?
Yes. After purchase and activation, follow the device guide to configure encrypted DNS, then fine-tune filtering rules to your needs. Setup steps may vary across OS versions; please check device compatibility first.
View Device SetupWhat if a normal website or app is mistakenly blocked?
With the private service, you can locate the relevant domain in query logs and add an allowlist rule. For temporary access, pause the encrypted DNS setting on your device and re-enable it after troubleshooting.
View Troubleshooting StepsIs encrypted DNS equivalent to a VPN or complete security?
No. DoH / DoT only encrypts queries between your device and the DNS service; it does not proxy all network traffic. Domain filtering also cannot replace fraud awareness, security software, or open family communication.
