• pfSense: `198.244.242.34/32`
• Cloudflare WAF: Block with expression `ip.src eq 198.244.242.34`
• AWS WAF: Add `198.244.242.34/32` to deny list

## Analyst Notes

1. Contextual Risk: While the IP itself shows no malicious activity, the high-abuse-density neighborhood warrants monitoring. Correlate with other IPs in the 198.244.242.0/24 block.

2. Legitimate Use Case: The ahrefs.net association suggests potential legitimate SEO/marketing infrastructure use.

3. False Positive Consideration: The moderate risk score (40) may reflect neighborhood abuse patterns rather than individual IP behavior.

4. Action Threshold: Consider blocking only if correlated with actual malicious activity or policy requirements.
