## Analyst Notes

This IP address represents a legitimate AWS cloud infrastructure endpoint with moderate risk scoring primarily attributable to DNS blacklist listings. The clean subnet classification and absence of open ports or active threat indicators suggest this endpoint is not currently being used for malicious purposes. The moderate risk score warrants monitoring but does not indicate immediate threat. SOC analysts should verify the reason for DNS blacklist inclusion through RDAP abuse contact procedures if traffic from this IP is observed. No immediate threat escalation required.
