---
**Key Risk Indicators**
- Risk Score: 50 (Moderate Risk)
- Subnet Abuse Density: 51.39% (High Abuse Classification)
- Threat Observations: 26 signals over 30 days, including 1 DNSBL listing and 8 DNS-related observations.
- Network Role: Cloud compute infrastructure (OVH-hosted), no direct malware or attacker indicators.
---
**Ownership & Geolocation**
- Registrar: OVH (ASN 16276)
- Organization: Ahrefs Pte Ltd (SEO tool provider)
- Geolocation: Listed as Canada (QC) with a Singapore city tag (potential data discrepancy).
- ISP: OVH (cloud hosting provider).
---
**Threat & Behavioral Context**
- No Malware/Attacker Indicators: No known campaigns, spam, or Tor/VPN associations.
- DNS Security: Valid DNSSEC, CAA records, but 2 DNSBL listings (e.g., Spamhaus, Barracuda).
- Subnet Neighbors: 251 total IPs in 142.44.225.0/24; 129 are flagged as high-risk.
---
**Actionable Insights**
1. Monitor Subnet Activity: High abuse density in the subnet suggests potential for lateral movement or compromised hosts.
2. Verify Geolocation Discrepancy: Investigate why the IP is tagged as Singapore despite being registered to a Canadian entity.
3. Review DNSBL Listings: Confirm if the IP is falsely flagged or part of a legitimate service (e.g., Ahrefs).
4. Cloud Provider Security: Ensure OVH’s infrastructure is configured to mitigate abuse (e.g., rate limiting, access controls).
---
**Recommended Actions**
- Firewall Rules: Block high-risk neighbors using subnet-based rules (e.g., `142.44.225.0/24`).
- DNS Monitoring: Validate DNS records for Ahrefs.net to prevent spoofing.
- Continuous Monitoring: Track changes in the subnet’s abuse density and correlate with Ahrefs’ infrastructure.
