2. Subnet-Level Monitoring: Given the high abuse density (0.7344) of the /24 subnet, apply broader monitoring to adjacent IPs.
3. Geographic Verification: The Canada/Singapore geolocation inconsistency warrants additional validation before deployment in geo-restricted contexts.
4. DNSBL Review: Single DNSBL listing detected; verify specific listing and assess impact on reputation.
5. Standard Cloud Infrastructure Handling: Treat as legitimate cloud hosting with moderate risk profileβno immediate blocking required unless specific threat activity is observed.
