# IP INTELLIGENCE BRIEFING

Target: 198.244.168.1/32

Classification: Moderate Risk / Cloud Infrastructure

Date: Current

Source: IPDebrief Intelligence Platform

## EXECUTIVE SUMMARY

IP 198.244.168.1 is a cloud-compute instance hosted within OVH infrastructure, associated with the Ahrefs Pte Ltd organization. The IP presents a moderate risk profile (Score: 40) with no active threat indicators. However, the /24 subnet demonstrates elevated abuse density (0.7695), suggesting potential collateral risk from neighboring addresses. No direct malicious activity observed; the IP serves as a firewalled endpoint with no open services.

---

## OWNERSHIP & INFRASTRUCTURE

Note: Control plane data indicates RPKI state and IRR consistency pending validation. Delegation age: 9,251 days.

---

## GEOLOCATION & DNS

Geographic Discrepancy: ASN registry indicates FR (France) allocation (2001-02-15), while geolocation data points to England. This inconsistency warrants monitoring.

---

## THREAT ANALYSIS

Behavioral Status: No persistent malicious activity. Threat observation count: 1. Stability score: 0.

---

## NEIGHBORHOOD CONTEXT

Critical Finding: The /24 subnet shows significant abuse density with 197 of 256 total IPs flagged as threats. This elevated neighborhood risk suggests compromised infrastructure sharing. Neighboring IPs (198.244.168.0-5) all show risk scores of 40 with authority scores of 50.

---

## SERVICES & NETWORK ROLE

Analysis: The target IP appears to be a backend or management endpoint with no exposed services. This is consistent with cloud infrastructure hosting.

---

## OBSERVATION HISTORY

## ACTIONABLE RECOMMENDATIONS

Immediate Actions

1. Block at Edge: Apply firewall rules for traffic from 198.244.168.1/32. Recommended ruleset:

- iptables: `iptables -A INPUT -s 198.244.168.1 -j DROP`

- nftables: `nft add rule inet filter input ip saddr 198.244.168.1 drop`

- Cloudflare WAF: Block with expression `ip.src eq 198.244.168.1`

2. Monitor Neighbors: Track adjacent IPs in 198.244.168.0/24 range. High abuse density (0.7695) indicates potential lateral threat vectors.

3. Validate DNS Records: Forward resolution unconfirmed for proxy-uk001-san1.ahrefs.net. Investigate DNS propagation status.

Long-Term Considerations

• Subnet Risk Assessment: The /24 subnet contains 197 threat-siblings. Consider broader segmentation policies for this OVH prefix.
• Geolocation Verification: Discrepancy between ASN registry (FR) and geolocation data (GB) requires validation.
• Reputation Monitoring: DNSBL listing count (1/8) suggests potential takedown or abuse history.

---

## RISK ASSESSMENT SUMMARY

Assessment Rationale: The target IP itself shows no active malicious indicators. However, the high-abuse neighborhood classification and 197 threat-siblings create contextual risk that warrants defensive posture. Recommend blocking while continuing surveillance for neighborhood correlation.
