2. Infrastructure Classification: Despite NETCITI-ID ownership, no cloud/hosting/proxy services detected—suggests the IP may be part of a firewalled infrastructure segment.

Recommended Monitoring Triggers:

• Service activation on previously closed ports
• DNS record creation
• Blacklist appearance
• ASN routing changes
