by default, quantum will give a port one IP address from any v4 subnet associated with the network, and one from any v6 subnet associated with the subnet. However, you can create your own port with multiple subnets, and then boot a VM with that port. You can create a port with IPs from different subnets by using the --fixed-ip option twice, each time specifying a different subnet. See example below.
