## EXECUTIVE SUMMARY

IP 142.44.228.88 is a firewalled hosting infrastructure address associated with OVH SAS (ASN 16276) and registered to Ahrefs Pte Ltd. The IP resolves to proxy-ca016-san88.ahrefs.net and operates within a high-abuse-density subnet (142.44.228.0/24). Despite no current active threat indicators, the subnet's abuse density of 0.6055 with 155 threat siblings out of 188 active IPs warrants defensive monitoring.

## OWNERSHIP AND INFRASTRUCTURE

• ASN: 16276 (OVH SAS)
• Network: OVH-CUST-281059695
• Organization: Dmytro, Ahrefs Pte Ltd
• RIR: ARIN
• Infrastructure Type: Cloud hosting (OVH)
• Service Purpose: Firewalled / No Services Detected

## GEOLOCATION ANALYSIS

• Claimed Location: Canada (QC)
• Inferred Location: Singapore (5598 km distance)
• Geolocation Confidence: Inconsistent (geoPlausible: false)
• RTT Violation: 27ms average RTT violates minimum possible 112ms for claimed 5598km distance

Significant geolocation data conflicts detected. The RTT violation suggests either false location claims or measurement anomalies. Additional validation recommended.

---

## THREAT INDICATORS

• Risk Score: 40 (Moderate)
• Abuse Confidence: Not elevated
• Blacklist Status: 0 blacklists
• Known Campaigns: None
• Tor Exit/Proxy: No
• Current Threat Feeds: Empty

No active threat indicators detected. However, the IP benefits from inherited risk scoring within its subnet context.

## RECOMMENDED ACTIONS

For SOC Analysts:

1. Monitor Contextually: Treat this IP within the context of its high-abuse subnet. Correlate with other traffic from 142.44.228.0/24.

2. Allow with Logging: Permissive rules acceptable if logging enabled. No immediate blocking required.

3. Monitor for Service Changes: The IP is currently firewalled with no services. Any service launches warrant investigation.

4. Geolocation Validation: The RTT violations suggest spoofed location data. Verify actual traffic origin independently.

5. Subnet-Level Analysis: Consider broader subnet analysis given 155 threat siblings in the same /24.

Recommended Firewall Rules:

```

# Allow with logging (if defensive monitoring enabled)

iptables -A INPUT -s 142.44.228.88/32 -j LOG --log-prefix "OVH-142.44.228.88: "

iptables -A INPUT -s 142.44.228.88/32 -j ACCEPT

# Block subnet-wide if risk escalation required

# iptables -A INPUT -s 142.44.228.0/24 -j DROP

```

## INTELLIGENCE NOTE

While 142.44.228.88 shows no current malicious activity, the subnet's high abuse density and significant number of threat siblings suggest this infrastructure may host or be associated with malicious actors. The geolocation inconsistencies warrant independent verification before allowing inbound connections. SOC teams should maintain awareness of subnet-level risk when evaluating traffic from this IP range.
