3. DNSBL Monitoring: Investigate the single DNSBL listing; may indicate prior reputation issues

4. Geolocation Validation: Consider RTT-based geolocation validation given ICMP blockage

Firewall Rule Consideration:

• If blocking: `iptables -A INPUT -s 5.167.70.245/32 -j DROP`
• If monitoring: Add to observation list with risk threshold of 50+
