IP Intelligence Briefing: 54.39.89.209/32

*Generated via IPDebrief Analysis*

---

**1. Risk Profile**

• Risk Score: 40 (Moderate Risk)
• Provider: OVH (ASN 16276)
• Ownership: Dmytro, Ahrefs Pte Ltd (OVH-CUST-281059691)
• Geolocation: Canada (QC, Beauharnois) – flagged as geographically implausible (RTT anomaly).
• Network Role: CloudCompute (OVH infrastructure).

---

**2. Threat Indicators**

• No direct malicious activity: No indicators of compromise (IOC), spam, or known attacker associations.
• DNS:

- PTR record: `proxy-ca012-san209.ahrefs.net` (resolves to ahrefs.net).

- No email authentication (SPF/DKIM) detected.

• TLS/Services: No open ports or TLS certificates observed.

---

**3. Observation History**

• Recent Activity (2026-06-18):

- Minimal risk score (0.2174) with DNSSEC and CAA validation.

- Subnet abuse density: 0.61 (high abuse risk in the 54.39.89.0/24 network).

• Historical Trends:

- No persistent threats; 1 observation recorded in the past 30 days.

---

**4. Network Relationships**

• Subnet: 54.39.89.0/24 (OVH-CUST-281059691).
• Neighbors:

- 100 IPs in the subnet, 157 flagged as "threat siblings" (high abuse density).

- 61.33% of subnet IPs associated with high-risk activity.

• Connections: Linked to ahrefs.net (proxy hostname).

---

**5. Key Findings & Recommendations**

• Cloud Compute Risk: The IP is part of OVH's cloud infrastructure, likely a compute instance. Monitor for unusual outbound traffic.
• Subnet Abnormality: High abuse density in the 54.39.89.0/24 subnet (61.33% high-risk IPs). Investigate if the IP is part of a compromised network.
• Geolocation Anomaly: Geolocation data is inconsistent with RTT measurements (expected 112.6ms vs. observed 27ms). Verify if the IP is spoofed or misconfigured.
• DNS Security: Ensure ahrefs.net’s DNSSEC and CAA records are validated to prevent spoofing.

---

Actionable Next Steps:

• Monitor the 54.39.89.0/24 subnet for lateral movement or command-and-control activity.
• Validate DNS configurations for the ahrefs.net domain.
• Confirm if the IP’s cloud provider (OVH) has mitigated subnet-level abuse.
