## Intelligence Narrative
IP 142.44.220.139 is a cloud-hosted address on OVH infrastructure, registered to ahrefs.net. The IP resolves consistently to legitimate domain infrastructure but presents a significant geographic anomaly between its registration (Canada) and detected location (Singapore). The subnet 142.44.
.44.220.0/24 demonstrates elevated abuse density at 0.6836, with 175 out of 256 sibling IPs classified as threats. This contextual risk requires elevated monitoring despite the individual IP showing no active malicious indicators.
The DNSBL listing (1 of 8 total lists) combined with the high abuse density in the subnet suggests this IP may have been used for abuse campaigns in the past or is currently hosting compromised services. The absence of open ports and services indicates either defensive configuration or potential botnet command-and-control infrastructure.
Final Recommendation: Apply block rules to perimeter firewalls with 24-hour observation monitoring. Investigate the geographic discrepancy between registration (Canada) and detected location (Singapore) through reverse DNS and network flow analysis. Correlate any inbound/outbound traffic with known ahrefs.net patterns to determine if this is legitimate infrastructure or misconfigured abuse hosting.
Confidence Level: Moderate (0.68 based on data sufficiency)
Status: Pending correlation with internal threat detection systems.
