Re: [openstack-dev] [Networking] Allocation of IPs
Aaron, Because the create create_subnet API is the one that enables/disables the DHCP: quantum subnet-create network CIDR --enable_dhcp False Besides, the CIDR is actually the information that is sent to the DHCP to locate IP Addresses.

Re: [openstack-dev] [Networking] Allocation of IPs
Hi Edgar, I'm still not following. In your original question you asked how to you create a port and not allocate an ip address to it at all so that you can leverage a real dhcp server to do that. In order to do that you can create a network without a subnet but then you loose the ipam info in quantum. Or write a script that notifies your dhcp server the mac-ip bindings each instance should have. Am i missing something here?
