IP Intelligence Briefing: 54.39.6.27
Date: 2026-06-14
---
**1. Core Profile**
- Risk Score: 25 (Low Risk)
- Ownership: Registered to Ahrefs Pte Ltd (OVH ASN 16276), netname OVH-CUST-281059680.
- Geolocation: Quebec, Canada (QC), but geo-validation flags indicate implausibility due to RTT discrepancies (observed 30ms vs. expected 112.6ms for 5,629km).
- Network Role: CloudCompute infrastructure (OVH), hosting environment. No residential/mobile/residential indicators.
- Threat Indicators: No malicious activity detected (no malware, scans, or blacklisted domains).
---
**2. Observation History**
- Last 30 Days:
- Stability: Minimal fluctuations (risk score 25).
- Key Signals:
- DNSSEC valid, CAA records present.
- No active threats or campaigns.
- BGP route stability: 0 changes in 30 days.
- Notable: No spikes in risk or malicious behavior.
---
**3. Relationships**
- Linked Entities:
- OVH-CUST-281059680 (same network).
- ahrefs.net (PTR hostname: `proxy-ca001-san27.ahrefs.net`).
- No direct ties to known malicious organizations, domains, or certificates.
---
**4. Subnet Neighbors**
- Subnet: 54.39.6.0/24.
- Abuse Density: 46.44% (mixed risk).
- Neighbor Risk Distribution:
- High Risk: 0 IPs.
- Medium Risk: 79 IPs.
- Low Risk: 21 IPs.
- Notable: 111 active neighbors, 111 flagged as potentially abusive.
---
**5. Recommendations**
- Monitor Subnet: Given the 46.44% abuse density, investigate potential lateral movement or compromised hosts in the 54.39.6.0/24 subnet.
- Verify Geolocation: Discrepancy between reported location (Quebec, Canada) and RTT suggests potential spoofing or misconfigured infrastructure.
- Check Hosting Environment: OVH's cloud compute infrastructure may host legitimate services, but ensure no unexpected outbound traffic or resource exhaustion.
- No Immediate Action Required: The IP itself is low risk, but subnet-level risks warrant closer scrutiny.
