IP Intelligence Briefing: 91.224.92.190
Date: 2026-06-13
---
**1. Risk Profile**
- Overall Risk: Moderate (Risk Score: 55)
- Geolocation: United Kingdom (London), Latitude: 51.5, Longitude: -0.12
- Network Role: Firewalled server with no open services detected.
- Threat Indicators: No direct malicious activity observed (no known attackers, spam, or campaigns).
---
**2. Observational History**
- ICMP Validation: Failed (IP blocks ICMP probes).
- Operator Score: Minimal (0.13), suggesting low provider authority.
- DNS Configuration:
- PTR hostname: `srv-91-224-92-190.serveroffer.net`
- SPF record present, but no DMARC or CAA records, potentially exposing email vulnerabilities.
- Routing: BGP prefix `91.224.92.0/24` with stable route (no recent changes).
---
**3. Relationships & Subnet Analysis**
- DNS Associations: Linked to `serveroffer.net` (SPF only).
- Subnet Neighbors (91.224.92.0/24):
- High-Risk Neighbors: 8 IPs with risk scores ≥ 65 (e.g., 91.224.92.50, 91.224.92.99).
- Abuse Density: Low (0%), but 3 neighbors flagged in DNSBL lists.
- Notable: 91.224.92.190 has minimal risk compared to peers but shares the same subnet.
---
**4. Recommendations**
- Monitor Subnet: Higher-risk neighbors in the same /24 subnet may indicate shared infrastructure risks.
- DNS Security: Enable DMARC and CAA records for `serveroffer.net` to mitigate email spoofing risks.
- Network Visibility: Investigate why ICMP is blocked—could indicate firewall rules or evasion tactics.
- Firewall Rules: Consider blocking this IP or its subnet if monitoring higher-risk neighbors.
---
Conclusion:
The IP itself shows no direct malicious activity, but its subnet contains higher-risk IPs. SOC teams should prioritize monitoring the subnet for lateral movement or shared infrastructure compromises. DNS configuration gaps and ICMP blocking warrant further investigation.
