## Recommended Actions

Firewall/Network Rules

• Default Action: Allow with monitoring
• Block Threshold: Only if traffic exhibits known malicious patterns
• Subnet Awareness: Monitor subnet 51.195.215.0/24 for correlated abuse

SOC Guidance

1. Do not block this IP without additional context; it hosts legitimate Ahrefs proxy infrastructure

2. Monitor for anomalous traffic patterns given the high-abuse subnet environment

3. Correlate with known Ahrefs TLDs and proxy patterns (ahrefs.net)

4. Track subnet-level abuse density changes for early warning signals

Risk Mitigation

• Implement connection rate limiting if abuse patterns emerge
• Monitor for DNS queries to ahrefs.net subdomains
• Review traffic during high-volume scanning periods
