## Operational Notes

This IP is a residential endpoint within a major Chinese ISP network. While the risk score indicates elevated concern, the absence of active threat indicators and known campaign associations suggests the classification may stem from historical data patterns or network-level risk factors rather than confirmed malicious activity.

Decision Framework: Apply blocking rules with monitoring for 7–14 days. Re-evaluate if any observed behavior changes or additional threat intelligence emerges.
