to support IP address ranges for an existing network when that network profile is used in a VMware Aria Automation cloud template that uses external IPAM integration, you can configure a network profile.
An example is provided within the context of a vendor-specific sample workflow at Configure a network and network profile to use external IPAM for an existing network in VMware Aria Automation. The overall vendor-specific workflow for external IPAM integration is at Tutorial: Configuring VMware Cloud on AWS for VMware Aria Automation.
Note: You can assign an IPv6 address space to single and dual stacked workloads when an IPv6 address is requested per integration with an external IPAM system. This capability requires that the integrated external IPAM plug-in also supports IPv6.
