52.112.87.33
IP 52.112.87.33/32 was identified as Low Risk with a risk score of 25 and assigned to Microsoft Corporation (ASN 8075) within the 52.96.0.0/12 block. The address operates as Microsoft Azure cloud infrastructure, exposing HTTP and HTTPS services validated by a TLS certificate issued by Microsoft TLS G2 RSA CA OCSP 04 for Microsoft Teams router domains. Geolocation data placed the resource in San Francisco, US, though RTT measurements recorded a 8860km distance discrepancy against an 83ms minimum possible round-trip time. Threat indicators returned no known campaigns, active attacker flags, or spam sources, while behavioral logs showed zero enumeration strikes or WAF violations. Control plane analysis flagged one DNSBL listing, and the neighborhood classification remained clean. Due to signal contradictions regarding geolocation and routing, the assessment recommended monitoring with low severity.
