## SOC Analyst Notes

This IP demonstrates moderate risk primarily due to DNSBL listings rather than active malicious indicators. The absence of open services and threat indicators suggests the IP may be dormant, abandoned, or used for low-volume legitimate traffic. However, the presence of 2 DNSBL listings warrants monitoring. The adjacent subnet IP 88.130.153.77 (risk score 55) suggests potential correlation; consider blocking the entire /24 if traffic patterns justify it.

No immediate threat to infrastructure; maintain monitoring and apply firewall rules as recommended.
