SECURITY ACTIONS & RECOMMENDATIONS

• Firewall Rules: No immediate blocking required. IP shows no active malicious behavior.
• Monitoring: Monitor for route stabilization; current instability may indicate infrastructure changes.
• DNSBL Review: Two DNSBL listings require investigation if IP begins generating outbound traffic.
• Threat Level: Low. The moderate risk score derives from historical DNSBL presence rather than active threat activity.

INTELLIGENCE JUDGMENT

NOT A THREAT – The IP address represents a static, firewalled endpoint with no open services. The moderate risk classification is attributable to historical DNSBL listings rather than current malicious activity. No immediate defensive actions required beyond standard monitoring.
