You can use a third-party IPAM provider solution that you have imported, configured, and registered in vRealize Orchestrator to obtain IP addresses from that third-party provider.
You can create an external network profile that uses a registered third-party IPAM solution provider endpoint to obtain gateway, subnet mask, and DHCP/WINS settings.
You can define one or more network ranges of static IP addresses in the network profile for use in provisioning a machine. If you do not specify a range, you can use a network profile as a network reservation policy to select a reservation network path for a virtual machine network card (vNIC).For information about how to create an external network profile without using an IPAM provider or by using the supplied internal IPAM provider endpoint, see Create an External Network Profile By Using the Supplied IPAM Endpoint.
What to do next
You can assign a network profile to a network path in a reservation or a blueprint architect can specify the network profile in a blueprint. You can use the external network profile when you create an on-demand NAT or routed network profile.
