## SOC Analyst Notes

1. Block Decision: Recommend blocking this IP at perimeter firewalls and WAF based on high risk score (80/100) and DNSBL presence.

2. Subnet Correlation: Two additional IPs in the same /24 subnet (45.190.205.146 and 45.190.205.193) show identical high-risk scores. Consider subnet-level blocking if the target IP confirms malicious activity.

3. Geolocation Inconsistency: The geoPlausible flag being false warrants correlation with other indicators. The large 2500km accuracy radius suggests potential spoofing.

4. No Active Services: Despite high risk classification, no open ports or services were detected. This may indicate the IP is being used for scanning/probing activities or is simply inactive.

5. Operator Score: The minimal operator score (0.1304) suggests this IP is not part of a large hosting infrastructure, making it more likely to be associated with opportunistic abuse.
