## EXECUTIVE SUMMARY

IP address 142.44.220.211 is a cloud-based hosting resource operating within OVH infrastructure. The IP resolves to hostname proxy-ca006-san211.ahrefs.net, indicating association with the Ahrefs platform. While individual threat indicators are absent, the subnet demonstrates elevated abuse characteristics requiring contextual consideration.

## INFRASTRUCTURE PROFILE

---

## GEOLOCATION INTELLIGENCE

• Reported Location: Canada (QC), Singapore (city field)
• GeoPlausible Status: FALSE
• Critical Discrepancy: Distance calculation indicates 5,597.9km with RTT 27ms vs. minimum possible 112ms for that distance. Geolocation data is unreliable and should not be used for incident response.
• DNS PTR Record: proxy-ca006-san211.ahrefs.net

---

## THREAT ASSESSMENT

Direct Threat Indicators:

• No known attacker associations
• No Tor exit node activity
• No spam source classification
• Zero confirmed blacklist entries
• No active threat campaigns detected

Control Plane Signals:

• DNSBL Listed: 1 of 8 total lists
• Route Stability: UNSTABLE
• Operator Risk Score: 0.2174 (Minimal)
• RPKI State: Not evaluated

## NEIGHBORHOOD ANALYSIS (142.44.220.0/24)

The /24 subnet exhibits high abuse density requiring awareness:

• Abuse Density Score: 0.6836 (HIGH)
• Total Siblings: 256 IPs
• Active Siblings: 194 IPs (76% utilization)
• Threat Siblings: 175 IPs (71% of active addresses flagged)
• Subnet Classification: high_abuse
• Inherited Risk Score: 27/100

This indicates the subnet hosts significant malicious activity. Contextual risk elevation is recommended for traffic from this /24.

## OBSERVATION HISTORY

Analysis of 20 historical observations reveals:

• Consistent cloud/hosting infrastructure classification
• Persistent DNS records for ahrefs.net domain
• Recent activity observed June 2026
• No evidence of malicious signal evolution

---

## RECOMMENDED ACTIONS

Immediate Mitigation:

```bash

# iptables

iptables -A INPUT -s 142.44.220.211 -j DROP

# nftables

nft add rule inet filter input ip saddr 142.44.220.211 drop

```

Extended Controls:

• NGINX: `deny 142.44.220.211;`
• pfSense: `142.44.220.211/32`
• Cloudflare WAF: Block with expression `ip.src eq 142.44.220.211`
• AWS WAF: Add `142.44.220.211/32` to blocked addresses

---

## ANALYST NOTES

1. Subnet-Level Consideration: The 142.44.220.0/24 subnet shows 68% abuse density. Consider implementing broader /24-level blocking if threat correlation exists.

2. Geolocation Unreliability: Distance/RTT mismatch invalidates reported location data. Do not use for geo-fencing or forensic correlation.

3. Infrastructure Legitimacy: The hostname association with ahrefs.net suggests legitimate use, but the high-abuse subnet environment warrants monitoring for anomalous behavior patterns.

4. No Active Threats: Absence of direct threat indicators suggests this specific IP is not currently compromised or malicious, but contextual risk from the subnet environment remains relevant.
