## ANALYST NOTES
1. Geo-spoofing detected โ IP claims Canada location but RTT measurements indicate Singapore. Investigate if this is misconfiguration or deliberate masking.
2. High-abuse subnet โ 169 of 175 active siblings in the /24 subnet flagged as threats. Consider blocking the entire 142.44.220.0/24 subnet if business requirements permit.
3. Ahrefs association โ Despite DNS resolution to ahrefs.net infrastructure, no legitimate services detected (no open ports). May indicate compromised infrastructure or abandoned hosting.
4. Block recommendation supported by firewall rules generation, though disclaimer notes probabilistic nature. Combine with additional signals before enforcement.
