16.15.35.43
The IP address 16.15.35.43/32 was registered to Amazon.com, Inc. (AS16509) within the AMAZO-4 netblock. The address was classified as Low Risk with a risk score of 20 and presented no known threat indicators, blacklist hits, or associations with active attack campaigns. Network scanning identified open ports 80/tcp, 443/tcp, and 8080/tcp, and the TLS certificate matched Amazon S3 domains in the us-west-2 region. Behavioral analysis recorded zero incidents, no honeypot hits, and no WAF violations across the subnet.
A discrepancy was noted between the claimed geolocation in Portland, OR, and RTT physics measurements, which indicated a distance contradiction. Despite the clean reputation and lack of malicious activity, the recommendation was to monitor the address due to signal contradictions. Profile confidence remained very low, and the address was not flagged as persistently malicious.
