- Network Role: Cloud compute instance (OVH infrastructure), not residential, mobile, or CDN.
---
**2. Observation History**
- Recent Activity (2026-06-03):
- Geolocation: Confirmed as Canada (CA) with 3000km accuracy radius.
- DNS: Resolves to `proxy-ca005-san208.ahrefs.net` (Ahrefs domain).
- Network Stability: Low stability score (0), suggesting potential misconfiguration or transient routing.
- Operator Score: Minimal risk (0.2174), but stability issues persist.

**3. Relationships & Network Context**
- Linked Entities:
- Network: `OVH-CUST-281059684` (same subnet: 51.161.37.0/24).
- Domains: `ahrefs.net` (DNS resolver).
- Services: No open ports or TLS certificates detected.
- Subnet Analysis:
- 51.161.37.208/24 has 61 active IPs, with 69 threat siblings (medium/high risk).
- Abuse Density: 28.99% (moderate risk within subnet).
---
**4. Neighborhood Risk**
- Subnet: 51.161.37.0/24 (238 total IPs).
- Risk Distribution:
- Low Risk: 21 IPs (8.8%).
- Medium Risk: 79 IPs (33.1%).
- High Risk: 0 IPs.
- Notable Neighbors:
- 51.161.37.0/24 has 100 IPs, with no high-risk outliers.
---
**5. Recommendations**
- Monitor Subnet: The subnet has a moderate abuse density; monitor for new high-risk IPs.
- Verify Geolocation: Investigate the "Singapore" city label discrepancy in geolocation data.
- Network Stability: Check OVH infrastructure for potential misconfigurations affecting stability.
- DNS Security: Ensure DNSSEC and CAA records are properly configured for `ahrefs.net`.
Conclusion:
The IP is associated with a legitimate cloud provider (OVH) and appears to be a low-risk infrastructure asset. However, the subnet’s moderate abuse density and geolocation anomalies warrant further investigation to rule out misconfigurations or potential lateral movement risks.
