There is an option to run a DHCP server that will allocate IP addresses to virtual machines running on the network. When a subnet is created, by default, the subnet has DHCP enabled.
The node that runs the DHCP agent should run:
neutron-dhcp-agent --config-file <neutron config> --config-file <dhcp config>
Currently the DHCP agent uses dnsmasq to perform that static address assignment.
A driver needs to be configured that matches the plug-in running on the service.
