52.123.251.142
Intelligence analysis indicates IP 52.123.251.142/32 is owned by Microsoft Corporation (AS8075) within the 52.120.0.0/14 block. The address maintained a Low Risk reputation with a risk score of 20. Network scans identified open ports 80, 443, and 8443, serving HTTP and HTTPS services over HTTP/2. TLS certificates validated to Microsoft domains including outlook.com and live.com.
Behavioral metrics recorded no active attacks, WAF violations, or blacklisting activity. The surrounding neighborhood showed a mostly clean classification with an abuse density of 0.1429. However, geolocation validation flagged a contradiction where the claimed Redmond, WA location conflicted with RTT physics measurements, recording a distance discrepancy of 6078.4km against a minimum possible round-trip time of 121.6ms.
Operational recommendations classified the severity as low with a monitoring directive due to present signal contradictions and very low data confidence. No active campaigns or malicious indicators were linked to the address during the observation window.
