## RECOMMENDED ACTIONS

Firewall/Security Recommendations

Status: No specific firewall rules generated. Risk profile indicates low threat.

Monitoring Guidance

1. Monitor subnet activity: 43.75% abuse density suggests elevated risk environment

2. Track proxy behavior: DNS resolves to proxy hostname; monitor for suspicious proxy traffic patterns

3. Watch geolocation anomalies: Inconsistent RTT data may indicate spoofing attempts

4. Correlate with ahrefs.net: Legitimate service, but verify business purpose before allowing traffic

Risk Assessment

Current Threat Level: LOW

Recommendation: Allow with monitoring. The IP belongs to a legitimate service provider (Ahrefs) with proper cloud hosting infrastructure. However, maintain awareness of:

• Proxy-related hostname resolution
• Elevated subnet abuse density
• Geolocation data inconsistencies

---

Analyst Notes: Target appears to be legitimate hosting infrastructure for Ahrefs web service. While the proxy hostname and subnet abuse density warrant monitoring, no active malicious indicators present. Standard logging and traffic correlation recommended.
