---
**3. Threat & Malicious Activity**
- Threat Indicators:
- No malicious campaigns, blacklists, or spam sources detected.
- Geo Plausibility: False (potential mismatch between geolocation and network origin).
- Observation History:
- Stable over 30 days (0 route changes).
- TLS/HTTP scans show no vulnerabilities or exploits.
---
**4. Relationships & Neighbors**
- Network Relationships:
- Linked to LVSS-VN (Vietnam’s national network).
- No external malicious entities or subnets identified.
- Subnet Neighbors:
- No active IPs detected in the 42.96.16.0/24 subnet (neighbors tool returned empty).
---
**5. Recommendations**
- Monitor: Track geo plausibility discrepancies and ensure TLS configurations remain secure.
- Firewall: Allow standard ports (80, 443, 22) but block non-standard traffic (e.g., port 8080).
- DNS: Verify DNSSEC and SPF/DKIM records for `aicrm.com.vn` to prevent spoofing.
- Logs: Review server access logs for unusual activity (e.g., failed SSH attempts).
Conclusion: This IP is a legitimate web server in Vietnam with no immediate malicious indicators. However, the geo plausibility issue warrants further investigation.
