*Generated via IPDebrief tools: Profile, History, Relationships, and Neighborhood Analysis*
---
**Key Findings**
- Risk Profile: Moderate risk (65/100) with no active threat indicators (no malware, phishing, or spam associations).
- Ownership: Registered to DTAG-NIC (Deutsche Telekom AG) under ASN 3320. Mobile LTE/5G carrier: Telekom (Germany).
- Geolocation: Confirmed as Germany (Krefeld, North Rhine-Westphalia) via MaxMind, but some historical data shows conflicting "US" labels. Verify geolocation accuracy.
- Network Role: Mobile IP (LTE/5G), no cloud/Cdn/Vpn/Proxy services.
- DNS: Linked to `p5b38d5d4.dip0.t-ipconnect.de` (T-IPConnect, Germany). No email auth (SPF/DKIM) or domain hosting detected.
- Threat Observations: No known malicious campaigns, blacklists, or Tor exit nodes.
---
**Observation History**

**Recommendations**
1. Monitor Geolocation Discrepancies: Investigate why some historical data shows "US" labels. Potential spoofing or misconfigured DNS.
2. Track Mobile IP Behavior: Mobile LTE/5G IPs may have dynamic routing; ensure network policies account for this.
3. Verify DNS Integrity: Confirm `t-ipconnect.de` is legitimate. No email auth mechanisms detected.
4. Subnet Context: No immediate risks in the 91.56.213.0/24 subnet, but monitor for new activity.
