Allocate CIDRs
Follow the steps in this section to allocate a CIDR from an IPAM pool to a resource.
Note
The terms provision and allocate are used throughout this user guide and the IPAM console. Provision is used when you add a CIDR to an IPAM pool. Allocate is used when you associate a CIDR from an IPAM pool with a resource.
You can allocate CIDRs from an IPAM pool in the following ways:
Use an Amazon service that's integrated with IPAM, such as Amazon VPC, and select the option to use an IPAM pool for the CIDR. IPAM automatically creates the allocation in the pool for you.
Manually allocate a CIDR within an IPAM pool to reserve it for later use with an Amazon service that's integrated with IPAM, such as Amazon VPC.
This section walks you through both options: how to use the Amazon services integrated with IPAM to provision an IPAM pool CIDR, and how to manually reserve IP address space.
