104.44.43.64
Intelligence analysis identified IP 104.44.43.64 as part of Microsoft Corporation's infrastructure (ASN 8075, 104.40.0.0/13). The address was classified as Low Risk with a risk score of 25, though it carried a "Suspicious Host" tag in threat actor categorization. Geolocation data placed the resource in Boston, MA, US; however, physics validation contradicted this claim, noting an RTT of 23.0ms against a minimum possible 152.5ms for the 7626km distance.
Network role assessment indicated the IP operated as a CloudCompute and Hosting infrastructure with firewalled services and no open ports. Observations recorded 24 signals between 2026-08-29 and 2026-09-05, with no specific threat indicators or blacklist entries found. DNS hygiene scores remained poor due to missing SPF and DMARC records, while the operator score was labeled "Minimal."
Due to signal contradictions and insufficient data to classify intent, analysts recommended a Monitor action at low severity. No specific campaign correlations or active attack patterns were confirmed during the observation window.
