142.251.211.99
Intelligence Briefing: IP 142.251.211.99
Subject: 142.251.211.99/32
Classification: Low Risk (Risk Score: 20)
Organization: Google LLC (AS15169, GOOGLE)
Network Role: CloudCompute / Web Server
Assessment:
The IP address was identified as a legitimate Google infrastructure endpoint associated with the 142.250.0.0/15 CIDR block. Operational analysis confirmed the host operated HTTP and HTTPS services on standard ports 80 and 443, with a server banner identifying the instance as "gws". DNS hygiene scores remained excellent, with valid SPF and DMARC records in place for the 1e100.net domain.
Anomalies and Observations:
Geolocation validation flagged a contradiction between the reported coordinates (United States) and RTT physics measurements, marking the location data as implausible. TLS certificate analysis revealed an invalid configuration (CN=invalid2.invalid) triggered by a lack of SNI during the scan. Control plane analysis indicated the route was stable but lacked RPKI validation.
Threat Indicators:
No known malicious campaigns, blacklist matches, or active attacker indicators were observed. The neighborhood classification identified the subnet as mostly clean, though five threat siblings were present within the /24 block.
Recommendation:
The asset is classified as low severity with a recommendation to monitor for changes. No immediate firewall rules are required based on current signal data.
