- ASN: 13335 (Cloudflare, Inc.)
- Network: CLOUDFLARENET (arin)
- Geolocation: Netherlands (NL), North Holland, city unknown (latitude/longitude null).
- Network Role: CDN (Cloudflare infrastructure).
- Threat Indicators: No detected malware, phishing, or exploit activity.
---
**2. Observation History**
- Latest Scan (2026-05-29):
- No open ports, no TLS certificate, no HTTP title.
- Subnet abuse density: 0.3871 (moderate risk).
- Ownership Stability: Stable (no recent changes).
- Geolocation Discrepancy: Conflicting signals suggest possible U.S. origin (latitude 39.83, longitude -98.58) but no city/region data.
---
**3. Network Relationships**
- Linked Entities:
- Same network: CLOUDFLARENET (repeated in relationships).
- Subnet: 104.28.163.185/24.
- Neighbor Risk Distribution:
- High Risk: 3 IPs (e.g., 104.28.163.192, 104.28.163.200).
- Medium Risk: 24 IPs.
- Low Risk: 5 IPs.
- Abuse Density: 0.091 (low subnet-wide risk).
---
**4. Actionable Insights**
- Monitor Neighbors: High-risk neighbors (e.g., 104.28.163.192) may indicate malicious activity within the subnet.
- Verify Geolocation: Discrepancy between Netherlands and U.S. signals warrants further investigation.
- CDN Context: Cloudflare IPs are generally benign, but ensure no misconfigured services (e.g., exposed ports) are present.
- Blocklist High-Risk Neighbors: Consider blocking IPs like 104.28.163.192 if they are not part of expected traffic.
Recommended Actions:
- Check for misconfigured services on the IP.
- Monitor subnet for unusual traffic patterns.
- Validate geolocation data with additional sources.
