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

AI-generated assessment. Verify critical details independently.

The host address 213.235.25.2/32 was validated by the server and identified as a single host within the 213.235.25.0/29 block. Routing data attributes the address to GTT Communications Inc. (AS3257), with registration details pointing to a United Kingdom origin and the network name "HERMAN-MILLER-GTT." Geolocation tools assigned an approximate network location in Chippenham, England.

Service analysis classified the endpoint as firewalled with no active services detected. Direct TLS probes to ports 443 and 8443 returned unreachable status. Historical certificate data, however, indicated a past issuance by Fortinet (CN=S108FNTV24018228) for a FortiSwitch device, though this finding describes a probe result rather than live validity. The DNS hygiene assessment yielded a score of zero, reflecting that SPF, DMARC, and CAA records were not checked or applicable, while DNSSEC status remained unknown.

The overall risk score was calculated at 15. Conflicting elements were observed between the routing operator's US location and the geolocation database's UK assignment, alongside the discrepancy between the "firewalled/no services" classification and the historical certificate presence. Due to the lack of live service detection and conflicting geolocation ownership data, corroboration through additional monitoring is recommended to fully characterize the endpoint's current operational state.
