IP Intelligence Briefing: 202.8.41.13
Generated for SOC Analysts
---
**1. Core Profile**
- Risk Score: Moderate (50/100)
- Ownership: Ahrefs Pte Ltd (ASN 140577, APNIC)
- Geolocation:
- Country: United States (VA, Ashburn)
- Inferred via DNS and BGP, but geoplugin confidence is low (0.28).
- Threat Indicators: No malicious activity detected (no blacklists, campaigns, or TLS anomalies).
- Network Role: Unknown infrastructure type; no public services (ports, TLS, or HTTP banners).
---
**2. Observation History**
- Key Findings:
- Geolocation Discrepancy: A probe detected a 6312km distance (6312.5km) but claimed latency (27ms) is inconsistent with expected minimum RTT (126ms).
- BGP Data: ASN 140577 (Ahrefs) owns the 202.8.40.0/23 subnet.
- Operator Score: "Basic" (0.3478), indicating potential operational risks.
- Trend: No persistent threats; zero threat observations in 30 days.
---
**3. Network Relationships**
- DNS Associations:
- Linked to `sardine269.ahrefs.net` (PTR record).
- No email auth (SPF/DKIM) detected.
- Network Context:
- Part of the "AHREFS-CRAWLER-A-USA" subnet (202.8.40.0/23).
- No CDN, cloud, or mobile carrier indicators.
---
**4. Neighborhood Analysis**
- Subnet: 202.8.41.13/24
- Risk Distribution:
- 83% low-risk neighbors, 15% medium-risk, 0% high-risk.
- Notable neighbors:
- `202.8.41.8` (riskScore: 50), `202.8.41.14` (riskScore: 0).
- Abuse Density: 0% (low likelihood of subnet abuse).
---
**5. Actionable Insights**
- Monitor: DNS activity for `sardine269.ahrefs.net` to confirm legitimacy.
- Investigate: Geolocation inconsistency (RTT vs. distance) may indicate spoofing or misconfigured infrastructure.
- Network Segmentation: Ensure subnets with mixed risk levels (e.g., 202.8.41.0/24) are isolated.
- Threat Context: While not malicious, the IPβs ownership by Ahrefs (a crawler service) suggests it may be part of automated traffic.
Recommendation: No immediate blocking required, but continuous monitoring for anomalies is advised.
