IP Intelligence Briefing: 54.39.210.204
Date: 2026-06-09
---
**Core Profile**
- Risk Score: Moderate (40/100)
- Ownership: Owned by OVH (ASN 16276), registered to Dmytro, Ahrefs Pte Ltd.
- Geolocation: Canada (QC, Beauharnois), inferred with 3000km accuracy radius.
- Network Role: Cloud compute instance (OVH), part of a /24 subnet (54.39.210.0/24).
- Threat Indicators: No direct malicious activity detected (no malware, phishing, or exploit indicators).
---
**Key Observations**
1. Subnet Abuse Density:
- High abuse density (61.72%) in the 54.39.210.0/24 subnet.
- 158/256 IPs in the subnet flagged as threats, with 98% medium-risk and 2% high-risk.
- Inherited Risk: 24 (substantial exposure due to neighboring IPs).
2. Network Relationships:
- Linked to ahrefs.net via DNS (PTR hostname: `proxy-ca007-san204.ahrefs.net`).
- No direct ties to known malicious campaigns, honeypots, or blacklists.
3. Temporal Trends:
- No significant changes in risk signals over the past 30 days.
- Recent DNS resolution activity (2026-06-09) confirms legitimate domain association.
---
**Actionable Insights**
- Subnet Risk: The IP resides in a high-abuse subnet with a mix of compromised hosts. Monitor for lateral movement or traffic anomalies.
- DNS Association: While `ahrefs.net` appears legitimate, the IP’s subnet history warrants closer scrutiny.
- Mitigation: Consider blocking the entire 54.39.210.0/24 subnet if the network is compromised, given the high abuse density.

**Recommendations**
1. Investigate Subnet: Analyze traffic patterns in the 54.39.210.0/24 subnet for unusual outbound connections or C2 activity.
2. Validate DNS: Confirm if `ahrefs.net` is a trusted domain and ensure DNSSEC is enforced.
3. Monitor Reputation: Track the IP’s risk score over time, as abuse density in the subnet may evolve.
Threat Level: Moderate (subnetwork exposure) | Confidence: High (validated via IPDebrief tools)
