142.251.16.81
Intelligence profile for 142.251.16.81 indicated infrastructure belonging to Google LLC (ASN 15169) operating within the 142.250.0.0/15 block. The host functioned as a CloudCompute web server listening on ports 80 and 443 with a "gws" server banner. Reputation metrics assigned a Low Risk score of 25 with no blacklist associations. However, threat actor classification labeled the host as "Suspicious," and a signal contradiction flagged the claimed New York geolocation against observed 25ms RTT physics (minimum possible 152.5ms). The surrounding /24 subnet was classified as mostly clean with an abuse density of 0.0833. DNS hygiene remained excellent, validating SPF, DMARC, and CAA records. Due to signal contradictions and the suspicious host tag, the recommended action was to monitor the asset without immediate blocking.
