```
Cloud/CDN Integration:
- Cloudflare WAF: Block IP (expression: `ip.src eq 142.44.228.6`)
- AWS WAF: Add 142.44.228.6/32 to deny list
---
## ANALYST NOTES
- Geolocation Validation: Fails RTT plausibility check. IP claims Canadian location but RTT measurements indicate 5,597.9km distance, suggesting spoofed or inaccurate geo-data.
- Subnet Risk: High abuse density in /24 (68% threat ratio) warrants monitoring of adjacent IPs.
- Infrastructure: No open ports or active services detected. IP is firewalled.
- DNS Context: PTR hostname resolves to Ahrefs infrastructure (proxy-ca016-san6.ahrefs.net). Legitimate web crawler or SEO tool endpoint possible.
- Action Priority: Moderate. Block at perimeter but maintain visibility for threat hunting correlation.
