## Analyst narrative

This IP address is registered to Microsoft Corporation (ASN 8075) and operates as a web server providing services for Outlook and Office domains. While DNS hygiene shows SPF and DMARC configurations on Microsoft domains, the threat actor profile classifies the host as suspicious with a low risk score of 25. Geolocation analysis reveals a contradiction between the claimed Redmond location and RTT physics measurements, resulting in a very low confidence score and a recommendation to monitor the asset.
