## GEOLOCATION VALIDATION
| Parameter | Observation |
|---|---|
| **Reported Location** | Montreal, QC, Canada |
| **Country Code** | CA |
| **RTT Validation** | โ Geographic Inconsistency |
| **Claimed Distance** | 5,597.4 km |
| **Observed RTT** | 28.0โ31.0 ms |
| **Minimum Possible RTT** | 111.9 ms |
| **Conclusion** | **FAIL** โ RTT 28ms < minimum 111.9ms for claimed distance |
The geolocation data shows significant inconsistencies. The IP claims Montreal coordinates but exhibits RTT characteristics inconsistent with that geographic location, suggesting either misconfigured DNS or proxy behavior.

## SUBNET CONTEXT (167.114.139.0/24)
| Metric | Value |
|---|---|
| **Abuse Density** | 0.7539 (High Abuse) |
| **Subnet Classification** | High Abuse |
| **Total Siblings** | 256 |
| **Active Siblings** | 211 |
| **Threat Siblings** | 193 |
| **Inherited Risk** | 30 |
Neighborhood Risk Distribution:
- High Risk: 0 IPs
- Medium Risk: 99 IPs
- Low Risk: 1 IP
The subnet demonstrates elevated abuse activity with 193 threat-sibling IPs out of 211 active addresses. This contextual risk suggests the /24 block is associated with legitimate but high-traffic infrastructure that may attract abuse vectors.

## OBSERVATION HISTORY
Total Observations: 21
Key Temporal Signals:
- 2026-06-20: Routing and reputation signals collected (confidence: 0.24)
- 2026-06-15: Geolocation data inconsistent with RTT measurements
- 2026-06-15: High abuse subnet classification confirmed
Risk Trend: No persistent threat pattern detected. The IP shows threat persistence days of 0, indicating transient rather than sustained malicious activity.
---
## RELATIONSHIP GRAPH
Primary Associations:
- Same Network: OVH-CUST-281059679 (41 relationship entries)
- Network Type: Cloud infrastructure customer subnet
- Certificate Matches: 0
- Campaign Correlations: 0
The IP demonstrates no connections to known malicious campaigns or certificate-based relationships.

## SOC ANALYST RECOMMENDATIONS
Immediate Actions
1. Monitor but Do Not Block: The IP presents moderate risk with no active threat indicators.
2. Verify Application Traffic: Confirm whether the DNS hostname `proxy-ca000-san163.ahrefs.net` is legitimate for your operations.
3. Subnet-Aware Filtering: Consider implementing rate-limiting for the 167.114.139.0/24 subnet given the 75% abuse density.
Firewall Rules (iptables example)
```bash
# Rate-limit traffic from the subnet (subnet-level protection)
iptables -A INPUT -s 167.114.139.0/24 -m limit --limit 10/min -j ACCEPT
iptables -A INPUT -s 167.114.139.0/24 -j DROP
# Monitor specific IP for 30 days
iptables -A INPUT -s 167.114.139.163 -m limit --limit 5/min -j ACCEPT
```
Monitoring Priorities
- Track for any service port openings (currently firewalled)
- Monitor for DNSBL additions
- Watch for RTT/geolocation data normalization
---
## CONCLUSION
IP 167.114.139.163 is a cloud compute endpoint hosted on OVH infrastructure with moderate risk characteristics. The primary concern is contextual risk from the high-abuse-density subnet rather than direct malicious activity. No immediate blocking is warranted, but implement subnet-level rate limiting and continue monitoring for behavioral changes.
Confidence Level: High (based on 21 historical observations)
Recommended Action: Monitor / Rate-limit subnet
