13.107.219.38
Intel data indicated 13.107.219.38 was Microsoft Corporation infrastructure (ASN 8075). The address functioned as Azure cloud compute services in Redmond, Washington. Geolocation validation contradicted RTT physics measurements, flagging signal inconsistencies. The host served web traffic on ports 80 and 443 using an *.azureedge.net certificate.
Threat analysis assigned a Low Risk score of 25. The address was not listed as a known attacker, Tor exit, or spam source, with zero threat indicators and one DNSBL listing among eight total checks. Neighborhood analysis showed a 0.25 abuse density with two threat siblings within the /24 subnet. Behavioral logs recorded no incidents or enumeration strikes.
Despite the low risk classification, the recommendation was to monitor due to signal contradictions and a very low confidence score of 0.2833. Route stability was recorded as false, and control plane data lacked RPKI or IRR consistency. Data freshness confirmed active observations within the last week.
