## SECURITY ACTIONS & RECOMMENDATIONS

Status: No immediate firewall rules required

Recommended Actions:

1. Monitor neighborhood traffic due to high abuse density (72.66%)

2. Allow legitimate Ahrefs traffic (verified DNS resolution)

3. No blocking required for this IP

4. Review subnet-level threat patterns for contextual awareness

Firewall Rules: None generated (risk score 40 below threshold)

---

## ANALYST NOTES

The target IP represents legitimate Ahrefs infrastructure within an OVH hosting environment. While the individual IP shows moderate risk with no direct threat indicators, the subnet's high abuse density suggests this IP should be monitored for anomalous behavior patterns. The absence of open ports indicates proper security hardening at the infrastructure level.

Confidence Level: High

Threat Status: Low (Infrastructure)

Action Required: Monitor
