VPC IPAM multi-account
Org-wide VPC IPAM across four accounts and two regions — delegated admin, RAM pool sharing, and pool-backed workload VPCs.
Delegate IPAM admin to a network account, build a three-level pool hierarchy, and RAM-share leaf pools to workload accounts so VPCs allocate CIDRs from shared pools.
The walkthrough covers the manual stack contract for pool IDs, formal allocations in Planning, and how Monitoring resource discovery differs from pool Allocations.
