# IP INTELLIGENCE BRIEFING

Target: 54.39.0.146/32

Date: 2026-06-20

Classification: Moderate Risk

---

## EXECUTIVE SUMMARY

IP 54.39.0.146 is a cloud-hosted infrastructure address associated with OVH Canada (ASN 16276) and the organization "Dmytro, Ahrefs Pte Ltd." The IP carries a risk score of 40 (Moderate Risk) and resides within a high-abuse density subnet (54.39.0.0/24) with an abuse density of 0.7188. No direct threat indicators or blacklistings were observed. Geolocation data shows validation inconsistencies requiring attention.

---

## OWNERSHIP & INFRASTRUCTURE

The IP is classified as cloud-hosted infrastructure with no detected open ports, services, or active web presence. Forward DNS resolution confirmed a single PTR record pointing to a proxy hostname.

---

## RISK ASSESSMENT

Threat Indicators: None detected. No known campaigns, threat feeds, or abuse indicators associated with this IP.

---

## NEIGHBORHOOD ANALYSIS (54.39.0.0/24)

The /24 subnet shows elevated abuse activity:

Risk distribution across the subnet:

• High Risk: 0 IPs
• Medium Risk: 36 IPs
• Low Risk: 64 IPs

The neighborhood context suggests this subnet hosts a mix of legitimate and potentially abused cloud resources, typical of large OVH hosting environments.

---

## OBSERVATION HISTORY

Total Observations: 20 (Latest: 2026-06-20 15:55 UTC)

Key historical signals:

• Network Classification: Consistent cloud hosting (OVH) across observations
• Geolocation: Canada (QC) with RTT validation failure (28ms observed vs 112.6ms minimum possible for ~5,629km distance)
• Abuse Density: Persistent high-abuse classification (0.7188)
• Ownership: Stable with no ownership changes recorded
• Threat Persistence: No persistent malicious behavior detected

Geolocation Validation Issue: The geolocation data shows a 5,629km distance discrepancy with an RTT of 28ms, which is below the minimum physically possible RTT of 112.6ms. This suggests inaccurate or spoofed geolocation data.

## RELATIONSHIP GRAPH

Total Relationships: 47

Primary relationship types:

• Same Network: OVH-CUST-281059683 (47 instances)

The IP is primarily linked to network-level entities within the OVH cloud infrastructure. No significant associations with organizations, hostnames, or certificates beyond the PTR record.

## INTELLIGENCE NARRATIVE FOR SOC ANALYSTS

IP 54.39.0.146 represents a moderate-risk cloud-hosted address within the OVH Canada infrastructure. The IP's PTR record indicates association with a proxy hostname under the ahrefs.net domain. While no direct threat indicators or blacklistings are present, the subnet (54.39.0.0/24) exhibits elevated abuse density (0.7188) with 184 threat-sibling IPs out of 227 active siblings.

The geolocation data requires scrutiny—the reported location (Beauharnois, QC, Canada) is geographically inconsistent with observed RTT measurements, suggesting potential data spoofing or routing anomalies.

Recommendation: Monitor inbound traffic from this IP for suspicious patterns. The moderate risk score and high-abuse neighborhood context warrant defensive blocking at perimeter controls while avoiding aggressive response without additional context. Consider blocklisting the /24 subnet if lateral movement or coordinated abuse is observed from neighboring IPs

---

## CONCLUSION

This IP represents a defensive priority case due to the combination of moderate risk score, high-abuse neighborhood context, and geolocation validation inconsistencies. While no active threat indicators are currently present, the subnet-level abuse density suggests this IP may be utilized for various non-malicious purposes (e.g., web scraping, hosting, or proxy services) that could intersect with organizational security boundaries.

Priority Level: Monitor

Recommended Action: Implement blocklist rules at perimeter controls; correlate with additional threat feeds before escalating to incident response
