- Subnet: 54.39.203.0/24 (high abuse density).
- DNS: Resolves to `proxy-ca008-san80.ahrefs.net` (Ahrefs Pte Ltd).
- No direct ties to known malicious campaigns or organizations.
---
**5. Neighbor Analysis**
- Subnet Summary:
- Total IPs: 256 (24-bit subnet).
- Active IPs: 191 (75% utilization).
- Threat IPs: 143 (56% of subnet).
- Risk Distribution: 2 low-risk, 98 medium-risk, 0 high-risk.
- Notable Neighbors:
- 54.39.203.0/24: 100% of IPs in subnet show mixed risk scores.
---
**6. Recommendations**
- Monitoring:
- Continuously monitor subnet for emerging threats (high abuse density).
- Validate geolocation anomalies via additional probes.
- Mitigation:
- Consider blocking high-risk neighbors (143 IPs) via firewall rules.
- Investigate DNSBL listing (1/8 total lists) for potential abuse.
Note: This IP is part of a cloud-hosted subnet with mixed risk. While not directly malicious, its association with a high-abuse subnet warrants closer scrutiny.
