Network hygiene assessments for SPF, DMARC, CAA, and DNSSEC were not performed. The risk score remained at zero, and the host was not classified as bogon, residential, or part of a known proxy, CDN, or cloud environment. Due to the lack of active service signatures and unverified anycast status, the specific physical location of the host relies on the approximate network location of the US assignment. Further monitoring is recommended to verify service status.
