40.99.236.66
Intellectual property analysis identified IP address 40.99.236.66/32 as an asset belonging to Microsoft Corporation (ASN 8075) within the MSFT network block (40.74.0.0/15). The infrastructure operated as Cloud Compute Hosting, actively serving web traffic on TCP ports 80 and 443. TLS certificate validation confirmed the domain outlook.com under Microsoft Corporation, with Subject Alternative Names covering *.hotmail.com, *.live.com, and *.office365.com.
Geolocation indicators were contradictory, reporting Canada (Québec) while other sources claimed the United States. Physical distance measurements contradicted latency data, showing a 29ms Round-Trip Time for a claimed distance of 5365km. Despite a Low Risk reputation score of 25, the host was tagged as Suspicious due to signal incoherence. DNS hygiene was rated Fair, with SPF and DMARC present but missing DNSSEC and FCR-DNS.
Recommendations dictated a medium severity rate-limiting policy (e.g., 5 requests per minute) due to multiple signal contradictions and an unreliable profile.
