Witness AI IP Assessment (AI-generated)
AI-generated assessment. Verify critical details independently.
On 191.180.161.164, the host resolved successfully. The address is allocated to Claro NXT Telecomunicacoes Ltda (AS28573) within the 191.180.0.0/14 block in Brazil. Geolocation data places the endpoint in São Paulo, SP. Network characterization identifies the system as a residential mobile endpoint, though the mobile classification is specific to the observed connection type rather than a fixed infrastructure trait. The host exhibits a zero-risk score with no TLS probes or TLS endpoints detected during the assessment. DNS hygiene checks returned absent or unknown status for CAA, DNSSEC, SPF, DMARC, and FCR-DNS, which, combined with the lack of TLS activity, precludes confirmation of active secure service deployment. Due to the residential nature of the connection and the absence of active TLS probes, the endpoint's current operational role remains unverified, and continued monitoring is recommended to assess any future service initiation.
