16.15.207.135
The IP address 16.15.207.135/32 was identified as a low-risk endpoint with a risk score of 20. Ownership records confirmed the address belongs to Amazon.com, Inc. (ASN 14618), specifically within the AMAZO-4 block. Infrastructure analysis indicated the device functioned as a Web Server utilizing AmazonS3 services. Network services included TCP 80, 443, and 8080, with TLS certificates issued by Amazon RSA 2048 M04 for s3.amazonaws.com domains.
Threat intelligence feeds returned no known attacker indicators, blacklist listings, or active campaign correlations. Behavioral analysis recorded zero WAF violations, honeypot hits, or enumeration strikes. The neighborhood classification remained mostly clean with an abuse density of 0.1333.
Validation checks revealed a contradiction between claimed geolocation data (Ashburn, VA) and RTT physics measurements, which recorded 28ms against a minimum theoretical distance of 126.2ms. Despite these signal contradictions and very low confidence metrics (0.25), no persistent malicious activity was observed. The recommended action was to monitor the address for changes in behavior or status.
