IP Intelligence Briefing: 54.39.210.2
*Generated via IPDebrief Threat Intelligence Platform*
---
**Core Profile**
- Risk Score: 40 (Moderate Risk)
- Owner: Dmytro, Ahrefs Pte Ltd (OVH network, ASN 16276)
- Geolocation: Registered to Quebec, Canada, but geo-validation flags it as implausible (RTT mismatch for distance).
- Network Role: CloudCompute infrastructure (OVH-hosted, no residential/mobile signals).
- Threat Indicators: No direct malicious activity detected (no malware, C2, or exploit signs).
---
**Observation History**
- Recent Activity:
- Observed June 10โ15, 2026, with stable BGP routing and no ownership changes.
- DNS resolution linked to `ahrefs.net` (PTR hostname: `proxy-ca007-san2.ahrefs.net`).
- Geo-validation anomalies: RTT of 28ms inconsistent with 5,629km distance.
---
**Network Relationships**
- Subnet: 54.39.210.0/24
- Neighborhood Risk:
- Abuse Density: 64.06% (high abuse classification).
- Neighbor Analysis: 164/256 IPs in subnet flagged as risky (avg. risk score 40).
- Key Neighbors:
- 54.39.210.0 (risk 40), 54.39.210.3 (risk 50), 54.39.210.5 (risk 40).
---
**Threat Context**
- No Direct Malicious Signals: No malware, phishing, or exploit indicators.
- Subnet Risk: High abuse density suggests potential for peer-to-peer malicious activity or compromised hosts.
- Geo-Plausibility: Discrepancy between registered location and network latency raises suspicion of spoofing or misconfigured infrastructure.
---
**Recommended Actions**
1. Monitor Subnet: Track neighbor activity for unusual traffic patterns or new risky IPs.
2. Block IP: Implement firewall rules to block 54.39.210.2/32 based on moderate risk and subnet context.
3. Verify Ownership: Confirm Ahrefs' infrastructure legitimacy and check for known compromises.
4. Investigate Geo-Discrepancy: Validate geolocation accuracy or potential spoofing.
---
Conclusion: While the IP itself shows no direct malicious activity, its association with a high-abuse subnet and geo-validation anomalies warrants further investigation. SOC teams should prioritize monitoring this subnet and consider blocking the IP to mitigate potential risks.
