## INTELLIGENCE RECOMMENDATIONS

1. Monitor subnet-level activity given the 75.8% threat density in the /24 block

2. Evaluate Ahrefs association - confirm whether traffic is related to legitimate SEO operations

3. Implement geolocation anomaly detection due to reported location inconsistencies

4. Consider subnet-wide blocking policies if threat activity correlates with observed patterns

5. Maintain logging for forensic correlation during incident investigations
