3.5.91.113
IP 3.5.91.113/32 was assessed as Low Risk with a risk score of 25. Ownership records linked the address to Amazon Data Services Northern Virginia (AS16509) within the AMAZON-S3 block (3.5.0.0/16). Operational data confirmed the node functioned as a Web Server hosting Amazon S3 infrastructure in the US East-2 region.
Technical analysis indicated open TCP ports 80, 443, and 8080. TLS certificate validation matched the subject `*.s3.us-east-2.amazonaws.com` issued by Amazon RSA 2048 M01. HTTP probes returned a 307 redirect status with a banner identifying the service as "AmazonS3."
Geolocation data claimed Columbus, OH, US; however, RTT physics measurements indicated a violation, showing a claimed distance of 6581km against an observed minimum possible RTT of 131.6ms versus a measured 37.0ms. Control plane metrics showed the address was listed on one DNSBL out of eight total lists checked. Behavioral analysis recorded zero honeypot hits, enumeration strikes, or incidents.
The profile was flagged for signal contradictions regarding geolocation and RTT consistency. Monitoring is recommended due to the presence of signal contradictions despite the Low Risk classification.
