## Analyst narrative

IP 52.123.251.26 is attributed to Microsoft Corporation (ASN 8075) and functions as a web server with TLS certificates covering Microsoft domains such as outlook.com and office365.com. Open ports 80, 443, and 8443 are active, while DNS hygiene is rated Fair due to partial SPF and DMARC implementation across the associated domain list. Although the overall risk score is low at 25, the host is classified as a "Suspicious Host" with threat indicators present and no specific campaign matches detected. Data confidence remains low at 0.3133, primarily due to a contradiction between the claimed Redmond geolocation and observed RTT physics measurements. The recommended action is to monitor the address for changes, maintaining a low severity status.
