DNS Pollution Check
Use dedicated detection nodes to identify DNS pollution and return a clear assessment.

Seven detection methods
A precise view of each network layer
Each method answers a different question. Choose nodes for base checks, then use GFW scenarios to assess DNS pollution and common blocking mechanisms.
Base checks
Executed by target, node, and method for API automation, troubleshooting, and individual status analysis.
| Method | Target | Best for | Key result |
|---|---|---|---|
DNS Resolve DNS_RESOLVE |
Domain | Resolution failures or inconsistent answers | DNS status and A records |
ICMP Ping ICMP_PING_CHECK |
IP address | Reachability, latency, and packet loss | Status, latency, and packet loss |
TCP Connect TCP_CONNECT_CHECK |
IP address and TCP port | Service port reachability | Connection status and elapsed time |
HTTP Host Reset HTTP_HOST_RESET_CHECK |
Domain and HTTP port | HTTP Host reset interference | HTTP response or reset status |
TLS SNI Handshake TLS_SNI_HANDSHAKE_CHECK |
Domain and TLS port | TLS SNI reset interference | Handshake or reset status |
GFW scenario checks
Organize detection capabilities into results that teams can understand and monitor over time.
GFW Full Check
Combine common GFW checks across selected nodes for a consolidated domain assessment.
GFW_FULL_DOMAIN_CHECK- Target
- Domain, ports, and selected nodes
- Best for
- Comprehensive domain blocking assessment
- Key result
- DNS, HTTP, and TLS results by node
Node selection
Base methods and GFW Full support selected nodes. DNS Pollution uses dedicated pollution detection nodes.
Result model
The interface groups outcomes into Normal, Indeterminate, and Blocked while preserving detailed statuses for API use and troubleshooting.
Put detection into a real workflow
Create scheduled Console tasks or submit asynchronous batches through the API.
