**Security Services**
- Open Ports: None detected
- HTTP/HTTPS: No services responding
- TLS/Certificates: None
- Status: Firewalled / No Services
**Recommendations for SOC Analysts**
1. MONITOR: No immediate blocking required, but maintain elevated monitoring due to high-abuse subnet context (66.41% abuse density)
2. CONTEXT AWARENESS: IP associated with ahrefs.net (SEO analytics infrastructure). Legitimate use case, but subnet shows elevated threat activity
3. GEOLOCATION DISCREPANCY: Singapore claim contradicted by RTT measurements. Do not rely on reported location for threat assessment
4. SUBNET CORRELATION: 170 threat siblings in same /24. Consider monitoring all 148.113.130.0/24 range for correlated activity
5. NO ACTION RECOMMENDED: Current IP shows no active malicious indicators, no open ports, and no known threat associations
---
Final Assessment: This IP represents legitimate OVH hosting infrastructure with moderate baseline risk due to subnet context. No immediate threat indicators present. Recommend standard monitoring with awareness of neighborhood threat patterns.
