## Witness AI - IP Assessment (AI-generated)

AI-generated assessment. Verify critical details independently.

The host at 100.40.185.91/32 was identified as part of the Verizon Business network (ASN 701) within the 100.32.0.0/13 CIDR block, registered with the American Registry for Internet Numbers (ARIN). Geolocation data placed the network infrastructure in Queens, New York, United States. The service profile indicated the host is firewalled with no active services detected, and no TLS endpoints were observed during probing. Ownership records attributed the routing operator to UUNET - Verizon Business, US, with the registrant country listed as the United States, though specific registrant contact details were unavailable. 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.
