- ASN: 9808
- Organization: Haijun Li (CMNET, China Mobile)
- Geolocation: Chengdu, Sichuan, China (30.67°N, 104.07°E)
- Network Role: Mobile device (China Mobile LTE/5G), no cloud/CDN/residential indicators.
- Threat Indicators: No malicious activity, spam, or known attacker associations.
---
**2. Observation History (30-Day Trend)**
- Geolocation Inference: 14 observations, with moderate confidence (0.52–0.30) for location in China.
- Network Classification: Consistently identified as mobile, no Tor/VPN/proxy activity.
- Threat Signals: No abuse confidence, blacklist, or campaign associations.
- Stability: No persistent malicious behavior; risk score remains stable.
---
**3. Relationships & Network Context**

- Subnet Analysis:
- /24 Subnet: 183.221.0.0/24
- Neighbor Risk: No sibling IPs detected; subnet abuse density is 0.
---
**4. Actionable Insights**
- No Immediate Threat: No malicious indicators, but the IP is a mobile device with no service ports open.
- Monitor for Changes: Track geolocation consistency and network role shifts (e.g., residential/cloud transitions).
- Owner Context: Individual ownership (Haijun Li) suggests non-enterprise activity, but further investigation into CMNET’s infrastructure may be warranted.
---
Recommendation: Low-priority for active mitigation. Use passive monitoring to detect anomalies in geolocation or network behavior. No firewall rules or alerts required at this time.
