Analyst Notes: This IP is associated with a known security research organization (Ahrefs) operating through OVH cloud infrastructure. The moderate risk score reflects the high-abuse neighborhood rather than direct malicious activity. Consider implementing subnet-level monitoring for 198.244.240.0/24 given the elevated threat density.
