Problem with network profile and external DHCP

Hi,

Is it possible to create a network profile without IP range, in order to use external DHCP.

If I create a network profile without ip range i got this error when I submit a VM request :

[catalog] ERROR com.vmware.vcac.platform.rest.client.error.ResponseErrorHandler.handleError:55 - [Rest Error]: {Status code: 400}, {Error code: 42300} , {Error Source: null}, {Error Msg: A server error was encountered. Error requesting machine. The list of unallocated IP addresses for the network profile (mynetworkprofile)  has been exhausted.}, {System Msg: Infrastructure service provider error}

I'm sure we can do it but I don't know how
