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

AI-generated assessment. Verify critical details independently.

The target IP address 173.40.65.164 belongs to Charter Communications Inc (AS20115), identified as a Residential Endpoint located in Rosemead, California, United States. Ownership records confirm the address is part of the RRHL netblock (173.40.0.0/14) routed by Charter Communications LLC. Geolocation data provides an approximate network location within the US, consistent with residential infrastructure classification.

DNS hygiene assessment yielded a score of zero due to the absence of SPF, DMARC, CCAA, FCRDNS, and DNSSEC records, though these omissions do not constitute a security failure for a residential endpoint. TLS probing attempts on ports 443 and 8443 returned unreachable statuses, indicating no active TLS services were detected on those endpoints. The risk score is currently zero, yet the lack of service availability and residential nature preclude definitive conclusions regarding malicious or benign activity. Continuous monitoring is recommended to observe future service activation or anomalous behavior.
