40.126.28.20
IP address 40.126.28.20/32 was registered to Microsoft Corporation (AS8075) within the 40.126.0.0/18 block. The asset operated as a CloudCompute web server hosted on Microsoft Azure, returning a Low Risk reputation score of 25 with zero blacklist entries. Active services included TCP port 80 (HTTP) and TCP port 443 (HTTPS). TLS validation confirmed the certificate subject `graph.windows.net` issued by DigiCert Inc.
Threat analysis indicated the host was not a known attacker, not a Tor exit, and exhibited no enumeration strikes or WAF violations. However, geo-validation revealed a contradiction where the claimed Redmond, Washington, location conflicted with RTT physics measurements indicating a 6707.5km distance against a 47ms RTT. Operational hygiene was rated Fair, with SPF and DMARC records present but lacking DNSSEC. The assessment recommends monitoring the asset due to signal contradictions and low severity risk.
