52.112.53.90
IP 52.112.53.90 was classified as Low Risk with a risk score of 25 and attributed to Microsoft Corporation (ASN 8075) within Microsoft Azure cloud infrastructure. The address operated as a web server hosting Microsoft Teams router services, presenting valid TLS certificates for *.trouter.teams.microsoft.com. Open ports 80 and 443 were observed with zero blacklist hits and no known campaigns.
Signal contradictions were identified in the profile. Geolocation data disagreed on country assignment between US and Singapore sources, and RTT measurements violated physics expectations regarding claimed distance versus measured latency. No active malicious behavior or incidents were recorded in behavioral logs.
Operational guidance recommended monitoring due to signal contradictions, despite the low-risk classification. Data freshness confirmed live observations with the most recent signal recorded in September 2026.
