## SOC Analyst Notes
This IP represents a residential endpoint with moderate risk factors primarily driven by DNSBL presence. The neighborhood shows some elevated activity, with five medium-risk neighbors. No evidence of infrastructure abuse (proxy, VPN, Tor) or persistent malicious behavior. Recommended approach: monitor for activity patterns and consider blocking only if correlated with specific threat indicators emerge. The geolocation validation anomaly (RTT discrepancy) suggests either measurement error or potential routing anomalies.
