# IP INTELLIGENCE BRIEFING

Target: 54.39.203.38/32

Classification: MODERATE RISK (Subnet: HIGH ABUSE)

Date: Current Intelligence Cycle

---

## EXECUTIVE SUMMARY

IP 54.39.203.38 operates within a high-abuse density subnet on OVH Canada infrastructure. While the individual IP presents moderate risk, the neighborhood analysis reveals significant malicious activity across the /24 block. The IP resolves to aresolves to a legitimate ahrefs.net hostname but shows geolocation inconsistencies and minimal operational indicators.

---

## NETWORK OWNERSHIP & INFRASTRUCTURE

The IP is associated with OVH-CUST-281059687 network block. DNS reverse resolution identifies proxy-ca008-san38.ahrefs.net, consistent with ahrefs.net infrastructure. No services detected on open ports; firewall configuration prevents direct connectivity.

---

## RISK ASSESSMENT

Individual IP Risk Score: 40 (MODERATE)

• Abuse Confidence: No known attacker status
• Threat Indicators: None detected (0 blacklist hits)
• Tor/Proxy/VPN: Not classified
• Campaign Affiliation: None identified

Neighborhood Risk Profile (54.39.203.0/24):

• Abuse Density: 0.6602 (HIGH)
• Subnet Classification: high_abuse
• Active Siblings: 222/256
• Threat Siblings: 169
• Inherited Risk Score: 26

Critical Finding: The IP resides in a subnet with elevated abuse activity. 169 of 222 active siblings (76%) show threat indicators. This contextual risk should factor into security decisions despite the moderate individual score.

---

## OBSERVATION HISTORY (25 Signals)

Recent observations (June 2026) confirm:

• Consistent cloud/hosting classification
• Persistent ahrefs.net DNS association
• Certificate verification: 0 certificates detected
• Geolocation Anomaly: Claimed Canada location conflicts with RTT measurements (26ms observed vs. 112.6ms minimum possible for 5,629km distance). This RTT violation suggests either:

- IP address spoofing/misconfiguration

- Traffic routing through intermediate locations

- Data center misreporting

---

## SECURITY ACTIONS

Recommended Mitigations:

1. Monitor Closely: High-abuse neighborhood warrants enhanced monitoring despite moderate individual risk

2. Geolocation Validation: Investigate RTT/geolocation discrepancy through additional validation

3. Traffic Analysis: Monitor for connections from this IP or related subnet IPs (54.39.203.0/24)

4. Firewall Considerations:

- Consider blocking if organization policy requires subnet-based controls

- Individual IP blocking may not address neighborhood risk

- Monitor for port scans or service probing

No immediate block recommended for defensive operations, but maintain awareness of subnet-level threat activity.

---

## INTELLIGENCE NOTES

• IP shows legitimate business hosting indicators (ahrefs.net)
• No active threat campaigns or known malicious associations
• Subnet-level abuse density suggests compromised infrastructure sharing or shared hosting abuse
• RTT geolocation violation requires further validation before drawing conclusions

Analyst Action: Monitor subnet activity patterns. Consider subnet-wide intelligence correlation if threat indicators emerge from related IPs in 54.39.203.0/24.
