---
**2. Observation History**
- Recent Activity:
- Geolocation data consistently reports Canada (QC, Beauharnois) with a plausible RTT of 27ms.
- BGP and DNSSEC validation confirmed (no route stability issues).
- No significant changes in risk scores or threat indicators over the last 30 days.
---
**3. Relationships & Network Context**
- Linked Entities:
- Subnet: 54.39.203.46/24 (OVH network, 250 total IPs).
- Neighborhood Risk:
- Abuse Density: 51.6% (high abuse classification).
- Threat Siblings: 129 IPs flagged in subnet (10% of total).
- Active IPs: 146 (48.7% of subnet).
- Provider: OVH (cloud hosting, no CDN/VPN/Proxy detected).
---
**4. Critical Findings**
- Geolocation Anomaly:
- RTT of 27ms is inconsistent with 5,628km distance (minimum plausible RTT: 112.6ms).
- May indicate routing anomalies or geolocation spoofing.
- Subnet Risk:
- High abuse density despite IP being clean. Monitor for lateral movement or compromised neighbors.
- Ownership:
- Ahrefs Pte Ltd (OVH customer) is a legitimate entity, but network segmentation may hide malicious activity.
---
**5. Recommendations**
- Monitor Subnet: Track high-risk neighbors (129 IPs) for suspicious behavior.
- Verify Geolocation: Investigate RTT inconsistency to rule out spoofing or routing issues.
- Network Segmentation: Ensure strict access controls to isolate cloud-hosted assets.
- Threat Feeds: Cross-check with DNSBLs (129 IPs in subnet are listed in 1/8 DNSBLs).
