16.15.33.47
The IP address 16.15.33.47 was associated with Amazon.com, Inc. (ASN 16509) and classified within the AMAZO-4 CIDR block. Network reconnaissance identified the system as an Amazon Web Services Web Server hosting S3 endpoints, confirmed by TLS certificate subjects and the AmazonS3 server banner.
Threat assessment indicated a Low Risk reputation with a risk score of 25. The asset maintained an open blacklist count of zero and was not flagged as a known attacker or Tor exit node. Active services included TCP ports 80, 443, and 8080.
Data integrity checks revealed specific anomalies. Geolocation validation reported a contradiction between the claimed Portland, OR location and minimum possible RTT measurements derived from physics constraints. Additionally, the system returned a 307 status code and lacked valid RPKI or CAA records.
Recommendation: Monitor. The network neighborhood was classified as clean with zero active threat siblings, but signal contradictions warrant low-severity observation.
