Intelligence analysis identified 23.103.238.217/32 as Microsoft Corporation (ASN 8075) infrastructure associated with the Outlook domain. The asset operated as a web server within a CloudCompute environment on ports 80 and 443. Geolocation data placed the host in Redmond, WA, US, though validation noted a contradiction between claimed coordinates and RTT physics measurements.
The asset maintained a Low Risk reputation with a risk score of 25 and zero blacklist entries. Network control plane analysis confirmed valid RPKI state but recorded three BGP route changes within the 30-day observation window. The immediate 23.103.238.0/24 subnet was classified as clean with one identified threat sibling. No active threat indicators, known campaigns, or attacker classifications were confirmed.
