142.251.151.4
Intellectual Property Intelligence Briefing
Target: 142.251.151.4/32
Classification: Low Risk (Risk Score: 25)
Ownership: Google LLC (ASN 15169), CloudCompute Infrastructure
Role: Web Server Hosting
Technical Profile:
The endpoint operates standard web services on TCP ports 80 and 443 with a server banner identifying the infrastructure as "gws". A TLS handshake was observed utilizing an invalid certificate subject ("CN=invalid2.invalid"). Control plane analysis detected a single DNSBL listing, though the overall reputation remains low.
Threat Indicators:
The asset was tagged as "suspicious" within the threat actor taxonomy; however, no specific campaigns, known attacker signatures, or active abuse indicators were linked to the address. The surrounding neighborhood (142.251.151.0/24) maintained a clean classification with zero threat siblings.
Anomalies & Contradictions:
Geolocation data reported the United States; however, Round-Trip Time (RTT) measurements contradicted this physical distance (7625km vs. minimum 152.5ms), indicating signal inconsistency. Confidence in data sufficiency was rated at 66.67%.
Operational Recommendation:
Monitor. While the asset is associated with a major cloud provider, signal contradictions regarding geolocation and certificate validation warrant continued observation rather than immediate blocking.
