IP Intelligence Briefing: 15.235.98.225
*Generated via IPDebrief Analysis*
---
**Overview**
- Risk Profile: Moderate Risk (Risk Score: 50)
- Ownership: Registered to Ahrefs Pte Ltd (OVH ASN: 16276)
- Geolocation: Singapore (CA), but geo-validation is implausible (3000km accuracy radius).
- Network Role: Hosting provider (OVH infrastructure, no public services detected).
- Threat Indicators: No direct malicious activity detected (no blacklists, campaigns, or known attackers).
---
**Key Observations**
1. Network Activity:
- Part of the 15.235.98.0/24 subnet with moderate abuse density (31.75%).
- 80 siblings in the subnet show threat activity, but the IP itself has no direct malicious signals.
- DNS: Resolves to `proxy-ca019-san225.ahrefs.net` (Ahrefs-owned domain).
2. Historical Signals:
- Stable ownership (no recent changes).
- Minimal risk over 30 days, with no persistent malicious behavior.
- Mixed network classification: 31% medium-risk neighbors, 69% low-risk.
3. Threat Context:
- No DNS-based threats, spam, or Tor activity.
- BGP analysis: Route stability flagged as "unstable," but no immediate exploitation risk.

**Recommended Actions**
1. Monitor Traffic: Track outbound connections from this IP, especially to untrusted domains.
2. Validate Geolocation: Investigate the implausible Singapore location; consider spoofing or misconfigured DNS.
3. Subnet Review: Assess the 15.235.98.0/24 subnet for potential lateral movement or compromised hosts.
4. DNS Security: Ensure DNSSEC and CAA records are enforced for `ahrefs.net` to prevent spoofing.
---
Conclusion: This IP is associated with a legitimate hosting provider but shows indirect network risks due to its subnet's abuse density. While not a direct threat, its mixed network context and geo-validation issues warrant closer scrutiny.
