// example, if you have separate routing and security needs for development and
// production applications, you can create a pool for each. For more information,
// see Create a top-level pool (https://docs.aws.amazon.com/vpc/latest/ipam/create-top-ipam.html)

	// If selected, IPAM will continuously look for resources within the CIDR range of

	// that will be allocated for these resources must not already be allocated to
	// other resources in order for the import to succeed. IPAM will import a CIDR
	// regardless of its compliance with the pool's allocation rules, so a resource
	// might be imported and subsequently marked as noncompliant. If IPAM discovers
	// multiple CIDRs that overlap, IPAM will import the largest CIDR only. If IPAM

	// In IPAM, the locale is the Amazon Web Services Region where you want to make an
	// IPAM pool available for allocations. Only resources in the same Region as the
	// locale of the pool can get IP address allocations from the pool. You can only
	// allocate a CIDR for a VPC, for example, from an IPAM pool that shares a locale
	// with the VPC’s Region. Note that once you choose a Locale for a pool, you cannot
	// modify it. If you do not choose a locale, resources in Regions others than the
	// IPAM's home region cannot use CIDRs from this pool. Possible values: Any Amazon
	// Web Services Region, such as us-east-1.
	Locale *string

	// The IP address source for pools in the public scope. Only used for provisioning
	// IP address CIDRs to pools in the public scope. Default is byoip . For more
