Risk assessment classified the address as Low Risk with a score of 25. The endpoint was not flagged as a known attacker, Tor exit node, or spam source. Control plane data indicated a single DNSBL listing out of eight queried sources. Geolocation data placed the host in New York, Virginia, though RTT measurements contradicted the physical distance claims. Behavioral analysis detected no honeypot hits or enumeration strikes.
Despite a generally clean neighborhood classification, signal contradictions in control plane and geolocation validation were recorded. Analysts recommended monitoring the address due to these inconsistencies.
