52.123.244.148
The intelligence profile identified 52.123.244.148 as legitimate infrastructure belonging to Microsoft Corporation (AS8075) within the United States. The asset functioned as a cloud compute web server, with active listening on TCP ports 80, 443, and 8443. TLS certificate validation confirmed association with outlook.com and Microsoft Corporation.
Threat analysis reported a low-risk reputation score of 15 with no active indicators of compromise, known campaigns, or abuse listings. The surrounding /24 subnet maintained a clean classification with zero threat siblings. Email authentication records included valid SPF and DMARC configurations.
Operational analysis flagged a contradiction between the claimed United States geolocation and observed Round-Trip Time physics, suggesting potential routing or measurement discrepancies. Despite the low-risk classification, the control plane indicated minor route instability with four changes within the previous 30 days. The recommendation classified the asset as legitimate infrastructure requiring monitoring due to signal contradictions.
