99.86.191.174
IP 99.86.191.174 was identified as a web infrastructure node operated by Amazon.com, Inc. (ASN 16509) within the CloudFront (AMAZO-CF) network block. The asset resolved to a CloudFront service purpose and presented HTTP/HTTPS endpoints on ports 80 and 443, utilizing an Amazon RSA 2048 M04 TLS certificate.
Operational risk assessment assigned a reputation of Low Risk with a score of 25. No active attack indicators, known campaigns, or enumeration strikes were observed during the analysis period. The neighborhood classification remained clean with zero threat siblings detected within the /24 subnet.
However, data consistency checks identified a contradiction between claimed geolocation in the US and Round Trip Time physics measurements. The asset appeared on one DNS blacklist out of eight total lists queried. Due to signal contradictions and low overall confidence, the recommendation was to monitor the address for changes rather than immediately blocking.
