- Ownership:
- ISP: OVH (ASN: 16276)
- Organization: Dmytro, Ahrefs Pte Ltd
- Network: OVH-CUST-281059686 (54.39.210.0/24)
- Geolocation:
- Country: Canada (QC, Beauharnois)
- Plausibility: Low (RTT anomaly: 27ms vs. expected 112.6ms for 5,629km)
- Network Role:
- Type: Cloud Compute (OVH Hosting)
- Services: No open ports; DNS resolves to `proxy-ca007-san199.ahrefs.net`
---
**2. Threat Indicators**
- No malicious indicators detected (no blacklists, campaigns, or known attackers).
- Subnet Risk: High abuse density (0.6039) in 54.39.210.0/24; 154 neighbors flagged as threats.
- DNS: Resolves to Ahrefs (legitimate SEO tool), but DNSSEC validation is enabled.
---
**3. Temporal Observations (2026-06-08)**
- Recent Activity:
- DNS resolution for `ahrefs.net` (CAA records present).
- Network classification as "high_abuse" with inherited risk score of 24.
- RTT anomaly suggests potential misconfigured routing or spoofed geolocation.
---
**4. Relationships & Neighborhood**
- Network Peers:
- Same ASN (OVH) and subnet (54.39.210.0/24).
- 146 active neighbors; 154 flagged as threats.
- Subnet Analysis:
- Abuse Density: 60.39% (high risk).
- Neighbors: Mixed risk scores (40β50), with 97% medium-risk IPs.
---
**5. Recommendations**
- Monitor Subnet: High abuse density in 54.39.210.0/24 suggests potential for lateral movement orε ³θ attacks.
- Verify Geolocation: Investigate RTT anomaly (27ms vs. 112.6ms) for spoofing or misconfigured routing.
- Check DNS: Confirm legitimacy of `ahrefs.net` and ensure DNSSEC is enforced.
- Segment Traffic: Consider isolating cloud compute workloads to mitigate subnet-wide risks.
Note: No direct malicious activity observed, but the IPβs subnet warrants closer scrutiny due to high abuse density.
