Intellectual Property Debrief Intelligence Briefing: IP Address 20.150.153.221/32
The target host address 20.150.153.221 was validated by the server and resolved to infrastructure owned by Microsoft Corporation (ASN 8075). Network role analysis identified the address as part of the Microsoft Azure cloud compute environment, specifically designated for web server purposes. Geolocation data places the approximate network location in Phoenix, Arizona, United States, though conflicting observations regarding the registrant country and routing operator origin were noted; the routing operator is explicitly listed as MICROSOFT-CORP-MSN-AS-BLOCK.
TLS probing yielded historical certificate data indicating an association with Microsoft Corporation's internal infrastructure. A certificate was observed issued by "CN=Microsoft TLS G2 RSA CA OCSP 04, O=Microsoft Corporation, C=US" for the subject "CN=*.gs-prod-wus3-xbl-01-latte.prodpme.gsinfra.playfab.com." The certificate was valid between November 1, 2026, and February 9, 2027, covering multiple Microsoft PlayFab and Xbox Live service domains including lobby.prod.pubsub.playfab.com, achievements.xboxlive.com, and prod.timeplayed.xboxlive.com.
DNS hygiene assessments returned no evaluated checks for SPF, DMARC, CAA, or DNSSEC, resulting in a current assessment score of zero. This lack of evaluation does not constitute a failure or proof of poor IP hygiene, as the checks were not performed. The risk score for the host is reported as zero. While the address is associated with legitimate Microsoft Azure cloud services, the absence of live TLS endpoint probes and the specific nature of the historical certificate suggest limited real-time observability. Monitoring is recommended to corroborate current service activity and maintain situational awareness.
