IP Intelligence Briefing: 15.235.27.103
*Generated via IPDebrief tools: profile, history, relationships, and neighborhood analysis*
---
**1. Core Profile**
- Risk Score: Moderate (40/100)
- Ownership:
- ASN: 16276 (OVH-CUST-281059692)
- Organization: Dmytro, Ahrefs Pte Ltd
- Geolocation: Singapore (CA), flagged as geoPlausible: false due to RTT discrepancy.
- Network Role: CloudCompute (OVH infrastructure), no services or Tor/VPN/Proxy indicators.
- Threat Indicators: No malicious activity detected (no abuse, spam, or campaigns).
---
**2. Historical Observations**
- Signal Consistency:
- Recent observations (June 13–17, 2026) show minimal risk scores (0.2174–0.25) and no persistent threats.
- Anomalous RTT: 23ms round-trip time for 6,082km distance, violating expected minimum (121.6ms).
- DNSSEC/Finding: Valid DNSSEC and CAA records, but DNSBL listing count (1/8) suggests potential misconfiguration.
---
**3. Relationships & Network Context**
- Linked Entities:
- Same network: OVH-CUST-281059692 (15.235.27.0/24).
- No direct ties to known malicious domains or organizations.
- Subnet Analysis:
- Abuse Density: 57% (moderate risk).
- Neighbor Risk: 100 IPs in subnet (256 total); 146 flagged as high-risk, 98 medium-risk.
- Inherited Risk: 22% (likely due to subnet-level abuse).
---
**4. Actionable Insights**
- Geolocation Discrepancy: Investigate spoofed location or proxy usage given RTT anomaly.
- DNS Configuration: Verify DNSBL (e.g., Spamhaus) listings and ensure DNSSEC/Caa compliance.
- Subnet Monitoring: Prioritize monitoring high-risk neighbors (146/256) for lateral movement or shared infrastructure risks.
- Cloud Compute Context: Ahrefs is a legitimate entity, but ensure cloud instance is not misconfigured or compromised.
---
Recommendation:
- Add to watchlist for ongoing geolocation anomalies and subnet-level abuse.
- Validate DNSSEC and CAA records with the registrar.
- Monitor neighbors for suspicious activity, particularly high-risk IPs in the 15.235.27.0/24 subnet.
