The /24 subnet (148.113.130.0/24) exhibits high abuse density (0.6055) with 155 of 256 sibling IPs flagged as threats. The subnet is classified as high_abuse with inherited risk score of 24. Of 100 sampled neighbors, 100 showed medium risk classification. This contextualizes 148.113.130.57 within a higher-abuse-density environment.
Historical Signals
Analysis of 21 historical observations reveals persistent patterns. Recent signals confirm high_abuse classification and operator score rated "Minimal." No observed threat persistence or ownership changes detected.
Recommendations for SOC
1. Monitor outbound traffic from this IP for anomalous patterns given neighborhood abuse density
2. Verify application legitimacy given ahrefs.net association (legitimate SEO/traffic analysis service)
3. Investigate geolocation spoofing indicators for potential evasion techniques
4. Consider enhanced monitoring during periods of increased subnet activity
Risk Rating: MODERATE โ Cloud hosting IP in high-abuse-density subnet with geolocation inconsistencies but no active threat indicators.
