**4. Recommendations**
- Monitor Subnet: The subnet has a high abuse density; prioritize monitoring related IPs for lateral movement or botnet activity.
- Verify DNS: Confirm ownership of `proxy-ca007-san213.ahrefs.net` to ensure it’s not being hijacked.
- Cloud Security: Ensure Ahrefs’ cloud infrastructure has proper firewall rules and intrusion detection enabled.
- Geolocation Discrepancy: Geolocation data is plausible (Beauharnois, QC), but no RTT or probe data available for verification.
