**2. Key Findings**
- Geolocation Discrepancy: While geolocation data suggests Germany, geoValidation flags it as "not plausible" with no RTT or distance data, raising doubts about location accuracy.

- Historical Activity:
- First observed on 2026-06-01 with no persistent malicious signals.
- No known campaigns, spam, or Tor associations.
---
**3. Threat & Mitigation**
- No Direct Threats: No indicators of malware, phishing, or exploitation.
- Monitor Neighbors: Watch 185.2.103.100 for anomalous behavior.
- Verify Geolocation: Investigate the lack of geoValidation data to rule out spoofing.
- DNS Monitoring: Track `contaboserver.net` for suspicious subdomains or email configurations.
---
**4. Recommendations**
- SOC Actions:
- Add 185.2.103.6/24 to passive monitoring with alerts for new connections.
- Validate geolocation using alternative probes (e.g., traceroute, DNS latency).
- Review Contaboβs security practices for potential shared hosting risks.
- Firewall Rules:
- Block 185.2.103.100 if it exhibits suspicious traffic patterns.
- Limit DNS queries to trusted domains (`contaboserver.net`).
---
Conclusion: This IP is associated with a hosting provider and shows no direct malicious activity. However, the unverified geolocation and one high-risk neighbor warrant further investigation.
