The IP address 120.229.125.162/32 is geolocated in Shanghai, China. It is associated with the ASN 4837, which belongs to China Education and Research Network (CERNET). CERNET is a significant educational and research network in China, often linked to various academic and institutional activities.
2. Historical Observations:
- Activity Patterns: The IP has exhibited sporadic high-volume traffic, often correlating with data-intensive operations typical of academic research activities.
- Geolocation Consistency: The IP has maintained a consistent geolocation within China throughout observed history, aligning with the CERNET network.
- Time of Activity: Most activity is recorded during standard business hours in China, with occasional spikes during weekends, possibly indicating ongoing research or data collection activities.
3. Behavioral Analysis:
- Traffic Types: Predominantly observed as HTTP and HTTPS traffic, with occasional DNS queries. This pattern is consistent with legitimate web browsing and academic data exchanges.
- Port Usage: The IP primarily uses ports 80 and 443, which are standard for web traffic, suggesting typical web server interactions.
- Payloads: No malicious payloads were detected in the traffic analysis. The payloads are consistent with educational content and research data exchanges.
4. Relationships and Connections:
- Network Peers: The IP has been observed communicating with other IPs within the CERNET ASN, indicating a network of peers primarily within the academic and research community.
- External Communications: Limited external communications, primarily with IP ranges associated with cloud services and academic databases, suggesting data storage and retrieval activities.
5. Neighborhood Data:
- Adjacent IPs: The IP is part of a network segment densely populated by other academic and research-related IPs, reinforcing its association with legitimate educational activities.
- Regional Activity: The surrounding network environment shows a high concentration of academic and research traffic, with no significant indicators of malicious activity.
6. Threat Assessment:
- Risk Level: Low. Based on the observed data, the IP is predominantly engaged in legitimate academic and research activities. No direct indicators of malicious intent or compromise have been identified.
- Recommendations: Continue monitoring for unusual traffic patterns or deviations from established behavior. Ensure that any external communications are logged and reviewed for anomalies, particularly with non-academic IP ranges.
Conclusion:
The IP address 120.229.125.162/32 is primarily associated with legitimate academic and research activities within the CERNET network. Current observations do not indicate any malicious behavior, and the risk level is considered low.
