Date: 2026-06-18
---
**1. Risk Profile**
- Risk Score: 40 (Moderate Risk)
- Threat Indicators: No known malicious activity, no DNS/IP blacklists, no campaign associations.
- Network Classification: Firewalled / No Services (no open ports, no TLS/HTTP services detected).
- Ownership: Registered to "sun ying" (ASN 4808, APNIC).
- Geolocation: China (CN), but no city/region specified.
---
**2. Observation History**
- Recent Activity:
- Observed on 2026-06-18 with "Minimal" risk assessment (operator score 0.2174).
- Historical data shows no persistent malicious behavior (threat persistence days = 0).
- Stability: Route stability flagged as unstable (BGP route changes in 30d = 0, but "isRouteStable" = false).
---
**3. Network Relationships**
- Linked Entities:
- Strong ties to the "UNICOM-BJ" network (repeated in relationships).
- No direct links to known malicious organizations, campaigns, or subnets.
- Subnet: 61.51.111.26/24, classified as "mostly_clean" with low abuse density.
---
**4. Neighborhood Analysis**
- Subnet Analysis:
- No neighboring IPs detected (neighborCount = 0).
- Subnet abuse density: 0% (low risk).
- Potential Context: Isolated IP with no sibling activity, suggesting limited network scope.
---
**5. Recommended Actions**
- Monitoring: Continue baseline monitoring for unexpected service changes or new threat indicators.
- Firewall: No immediate blocking required; ensure existing rules align with network segmentation policies.
- Investigation: Verify "sun ying" ownership legitimacy and confirm "UNICOM-BJ" network context (e.g., ISP/enterprise).
---
Conclusion:
The IP exhibits no active malicious behavior, but its isolated nature and lack of geolocation precision warrant further validation. No urgent action is required, but sustained monitoring is advised.
