18.239.183.32
IP address 18.239.183.32 was identified as a Low Risk asset (Risk Score: 25) owned by Amazon.com, Inc. (ASN 16509, AMAZON-CF). Technical analysis confirmed the host functions as a web server with CloudFront infrastructure, actively serving HTTP (TCP/80) and HTTPS (TCP/443) traffic. DNS records resolved to server-18-239-183-32.bos50.r.cloudfront.net, and email authentication standards (SPF and DMARC) were present.
Threat assessment tagged the host as Suspicious with moderate attribution confidence, though no specific threat indicators, blacklist entries, or known campaigns were recorded. A critical contradiction emerged in the geolocation data; the profile claimed US-MA (Boston), yet RTT physics measurements indicated a distance of 7,626 km against a minimum possible latency of 152.5 ms, with observed RTT values of 15-16.8 ms. The surrounding /24 subnet was classified as mixed with an abuse density of 0.2222.
Monitoring was recommended due to signal contradictions and low confidence scores, despite the overall Low Risk classification and lack of direct malicious activity indicators.
