18.239.166.126
The IP address 18.239.166.126 was identified within the AMAZON-CF network (ASN 16509) owned by Amazon.com, Inc. Reverse DNS records resolved the address to server-18-239-166-126.bos50.r.cloudfront.net. Service scanning detected no open ports, TLS certificates, or HTTP banners, indicating a firewalled infrastructure.
Threat intelligence feeds showed no association with known campaigns, spam sources, or active attackers. The risk score remained low at 20 with zero blacklist entries. DNS hygiene validated SPF and DMARC configurations.
However, geolocation data contradicted RTT physics measurements, recording a 15.0ms latency against a minimum possible of 152.5ms for the claimed United States coordinates. Overall profile confidence was rated very low due to insufficient data and signal contradictions. No malicious incidents were observed during the monitoring period.
The recommended operational posture is to monitor the address for behavioral changes, as the current signal contradicts expected network physics despite benign infrastructure classification.
