99.81.134.170
Intelligence Briefing: 99.81.134.170/32
The target IP was identified as an Amazon Web Services (AWS) infrastructure resource owned by Amazon Data Services Ireland Limited (ASN 16509). Geolocation data indicated Dublin, Ireland, though a contradiction existed between geospatial sources citing both the United States and Ireland.
Network analysis revealed the address resolved to an EC2 instance (`ec2-99-81-134-170.eu-west-1.compute.amazonaws.com`). No open ports, services, or server banners were detected, classifying the service purpose as firewalled. Behavioral data showed zero honeypot hits, enumeration strikes, or known campaign correlations.
Threat assessment assigned a Risk Score of 25 (Low Risk). The IP carried a blacklist count of zero, though one DNSBL listing was recorded among eight total lists. DNS hygiene was rated Good, with valid SPF and DMARC records confirmed. Despite the low risk profile, the control plane flagged route instability, and the profile overall confidence was rated Very Low due to data contradictions.
Recommendation: Monitor with low severity. Analysis indicated signal contradictions present—monitor for changes. No immediate firewall blocking is advised.
