3.5.133.236
Intelligence Briefing: 3.5.133.236/32
The IP address was identified as infrastructure belonging to Amazon Data Services Northern Virginia (ASN 16509). Network scans revealed open ports 80 (HTTP), 443 (HTTPS), and 8080 (HTTP-Alt). TLS certificate analysis confirmed the host served Amazon S3 services (`*.s3.us-east-2.amazonaws.com`). The system reported a reputation risk score of 25, classified as Low Risk, with zero blacklist hits.
Geolocation data indicated Columbus, Ohio, US, but RTT measurements showed a 38ms round-trip time contradicting the claimed 6581km distance. This signal contradiction was noted alongside a subnet abuse density of 0.0833 and a "mostly clean" classification. No known campaigns, attacker indicators, or spam activity were associated with the address.
The recommended action was to monitor the host for changes due to signal contradictions, maintaining a low-risk classification despite the validation discrepancies.
