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

AI-generated assessment. Verify critical details independently.

On 2026-01-04, the host 121.40.80.166/32 was resolved by the server. The address belongs to ALISOFT (AS37963), registered within the 121.40.0.0/14 block under ALIBABA-CN-NET in Hangzhou, Zhejiang, China. Geolocation data approximates the network location to Hangzhou; for anycast deployments, observed server locations may differ from the registration footprint. No services were detected on the host, and it is characterized as firewalled with no services.

DNS hygiene was not assessed; SPF, DMARC, and CAA records were not checked or not applicable, DNSSEC status is unknown, and FCR-DNS is not applicable. These missing or unverified records do not establish poor IP hygiene. The host's risk score is zero due to lack of observed malicious activity, but this does not prove legitimacy or the absence of hidden threats.

Recommendation: Continue monitoring the address for changes in service presence, DNS configuration, or behavioral indicators. Corroborate with additional telemetry before allowing unrestricted traffic.
