Analysis identified IP 4.155.90.37 as a Microsoft Azure cloud compute host within the 4.144.0.0/12 block owned by Microsoft Corporation. The asset presented a low-risk profile with a risk score of 25. No active threat indicators, known campaigns, or significant abuse history were found, though one DNSBL listing was recorded within the control plane data. Technical profiling confirmed port 443 was open over TCP using Microsoft Azure Application Gateway. TLS certificates were issued by Microsoft TLS G2 RSA CA. DNS hygiene records showed valid SPF and DMARC implementations. Geolocation data was flagged for contradiction, as the claimed Washington location did not align with physical distance measurements derived from Round-Trip Time. Operational metrics showed zero threat persistence days. Recommendations indicated monitoring due to signal contradictions regarding geolocation and control plane consistency, although the asset was classified as a clean hosting resource with low severity.
