**ASSESSMENT**

This IP presents a moderate-risk profile typical of cloud infrastructure used for various legitimate and potentially misconfigured purposes. The elevated risk score (65/100) combined with DNSBL listings suggests historical abuse activity, though no active threat indicators are currently observed. The clean subnet classification and lack of threat persistence indicate this may represent legacy reputation rather than current malicious activity. SOC teams should monitor but may consider blocking based on organizational security policies.
