IP Intelligence Briefing: 45.79.181.251
Date: 2026-06-07
---
**Core Profile**
- Risk Score: 40 (Moderate Risk)
- Provider: Linode (ASN 63949)
- Geolocation: Claimed NJ, US (Cedar Knolls), but RTT anomaly indicates plausible spoofing (observed RTT: 20ms vs. expected 119.8ms for 5989km).
- Network Role: CloudCompute (Linode infrastructure), no open ports or services detected.
- Threat Indicators: No malicious activity, no blacklists, no known campaigns, or DNS anomalies.
---
**Observation History**
- Last Scan: 2026-05-31 (ports scanned, no active services identified).
- RTT Anomalies: Persistent misalignment between geographic claims and network latency, suggesting potential spoofing or misconfigured routing.
- DNS Associations: Linked to `guernsey.scan.bufferover.run` (no known malicious history).
---
**Network Relationships**
- Subnet: 45.79.181.251/24
- Neighbors:
- 45.79.181.94 (Risk: 55)
- 45.79.181.104 (Risk: 55)
- Subnet abuse density: 0.6667 (mostly clean, but 2 high-risk neighbors).
- Shared Network: Linode (ASN 63949), no CDN/VPN/Proxy detected.
---
**Key Findings**
1. Low Direct Threat: No malicious indicators, but moderate risk due to network neighbors.
2. Geolocation Discrepancy: RTT data contradicts claimed location, warranting further verification.
3. DNS Context: Tied to `bufferover.run`, which appears benign but requires monitoring for unexpected behavior.
---
**Recommendations**
- Monitor Neighbors: Focus on 45.79.181.94 and 45.79.181.104 for potential lateral movement.
- Validate Geolocation: Investigate RTT anomalies to confirm IP legitimacy.
- Check DNS Behavior: Ensure `guernsey.scan.bufferover.run` is not repurposed for malicious activity.
- Maintain Baseline: No immediate mitigation needed, but continuous monitoring advised.
SOC Action: No immediate blocking recommended. Prioritize investigation into subnet neighbors and DNS ties.
