## Intelligence Notes
1. Hosting Context: IP is part of OVH cloud infrastructure hosting Ahrefs services. Legitimate traffic may originate from this IP.
2. Abuse Correlation: High subnet abuse density warrants defensive blocking despite individual IP cleanliness.
3. Geolocation Red Flag: RTT violation suggests potential spoofing; consider cross-referencing with additional geolocation signals.
4. No Active Threats: Current observations show no malicious activity, but neighborhood context suggests elevated risk environment.
