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

AI-generated assessment. Verify critical details independently.

On 173.177.21.140, the network is registered to Videotron Ltee (AS5769) in Laval, Quebec, Canada, within the 173.177.21.0/24 block. Geolocation data aligns with the routing operator's reported location, showing no conflict between the network's administrative registration and the approximate network location. The host presents a risk score of zero with no active TLS endpoints detected and no successful service probes recorded.

DNS hygiene for the associated domain videotron.ca returned unknown status for CAA and DNSSEC checks, while SPF, DMARC, and FCR-DNS were not checked; these missing validations do not establish poor IP hygiene. Network role analysis classifies the address as firewalled with no services exposed, and it is not identified as residential, mobile, proxy, Tor, CDN, cloud, or anycast infrastructure. Due to the absence of service probes and the firewalled state, the current profile indicates limited visibility into active host functions. Monitoring is recommended to corroborate the lack of service exposure and to track future activity, as a zero risk score does not preclude latent malicious behavior.
