## SOC RECOMMENDATION

Monitor or Block: The moderate risk score (40) combined with high-abuse neighborhood context (0.6953 abuse density, 178 threat siblings) suggests this IP should be blocked or monitored for suspicious activity. The presence of 8 DNSBL listings indicates prior abuse activity. Consider implementing subnet-level controls for 51.195.215.0/24 given the 72% threat sibling ratio.

*Note: These recommendations are probabilistic and should be combined with other threat intelligence signals before taking action.*
