Intellectual Property 40.64.66.34/32 is a single-host cloud computing resource hosted within the Microsoft Corporation infrastructure in the United States. The address resolves to the Microsoft Azure network, specifically associated with the AS8075 (MICROSOFT-CORP-MSN-AS-BLOCK) block registered in the ARIN RIR. Geolocation data places the server's approximate network location in Quincy, Washington. The network role is identified as a Web Server with a service purpose of hosting web applications.

TLS probing indicates a historical certificate association with a domain related to the PlayFab gaming infrastructure, specifically \`*.gs-prod-wus2-xbl-01-sunburst.prodpme.gsinfra.playfab.com\`. The certificate was issued by Microsoft TLS G2 RSA CA OCSP 02 and covers multiple subdomains including Xbox Live and PlayFab services (e.g., \`achievements.xboxlive.com\`, \`prod.pubsub.playfab.com\`). The certificate validity period extends from September 16, 2026, to December 25, 2026.

DNS hygiene checks for CAA, SPF, DMARC, DNSSEC, and FCR DNS were not performed, resulting in an unassessed score. No other TLS endpoints were observed. Due to the limited scope of current observations and the absence of live certificate validation or DNS record verification, the specific operational status of this host remains uncorroborated. Monitoring is recommended to track future certificate renewals or changes in DNS configuration.
