Waiting to run

Waiting to run

Enter a domain and click “Check Domain”. The result will appear after verification succeeds.

Result Guide

How to interpret the result

The free DNS check is best for quick confirmation of a high-risk issue. For business-critical domains, continuous monitoring is the safer approach.

No poisoning detected

The current check did not find obvious DNS poisoning, but that does not guarantee the domain will remain unaffected later.

Poisoning detected

The domain may currently be resolving to an abnormal IP and should be confirmed further and tracked continuously.

System error or retry

If an upstream request fails or verification does not complete, run the check again later.

Next Step

Need more than a one-off check?

The Weavebit Console provides a fuller monitoring layer for web accessibility from mainland China, especially for critical domains and user-facing entry points.

24/7 DNS poisoning monitoring

Create ongoing tasks for important domains and check them automatically at the frequency you choose.

ISP hijacking monitoring

Go beyond GFW DNS poisoning and detect hijacking by China Unicom, China Mobile, and China Telecom.

Alerting and API access

Use Telegram, email, and in-app notifications together with API keys, usage statistics, and billing statistics.
