## ANALYST NOTES

This IP belongs to Ahrefs' infrastructure—a legitimate SEO analytics service provider. The moderate risk score reflects the subnet's elevated abuse environment rather than confirmed malicious activity. SOC teams should:

1. Monitor for unusual traffic patterns from this IP range

2. Correlate with known Ahrefs traffic baselines

3. Consider subnet-level policies given the 153 threat siblings in the /24

4. Evaluate whether the risk score of 40 warrants blocking based on organizational threat tolerance
