IP 3.5.90.104/32 was identified as an Amazon S3 web server within the Amazon Data Services Northern Virginia network (ASN 16509). The asset carried a low risk score of 25 and was classified as a hosting provider. Despite clean behavioral indicators with no recorded attacks or honeypot hits, the profile flagged the host as suspicious due to signal contradictions. Geolocation data claimed Columbus, US, but RTT measurements indicated a distance of 6580km, creating a physics violation. The surrounding 3.5.90.0/24 subnet showed mixed classification with an abuse density of 0.2222 and four threat siblings. Monitoring was recommended with low severity due to the presence of signal contradictions.
