IP address 52.123.247.59/32 was identified as Microsoft Corporation infrastructure (AS8075) within the 52.120.0.0/14 block. The host operated as a CloudCompute and Web Server node serving Outlook services (outlook.com, hotmail.com, live.com) on ports 80, 443, and 8443. TLS certificate validation confirmed association with Microsoft Corporation and DigiCert.
Threat assessment recorded a Low Risk reputation (Score: 25) with zero blacklist entries and no active attacker indicators. Behavioral logs showed no honeypot hits, enumeration strikes, or WAF violations. However, geolocation validation flagged a contradiction between claimed location and Round Trip Time physics measurements. The adjacent subnet (52.123.247.0/24) exhibited mixed classification with an abuse density of 0.3273 and 18 threat siblings among 55 active peers.
The recommended action was to monitor the address due to signal contradictions despite the low overall risk score. No specific firewall rules were generated.
