Open Stack

An openstack deployment with an external DHCP server is definetely a possible scenario; I don't think it can be implemented out-of-the-box with the components provided by the core openstack services, but it should be doable and a possibly even a requirement for deployments which integrate openstack with systems such as Infoblox.
Therefore I would not disregard the possibility of an external DHCP server.
Regarding the new attributes, I pretty much agree on them. As there's overlap between enable_dhcp and address_mode, it might be worth defining a strategy for deprecating enable_dhcp by adding inclduing also a 'dhcpv4' valid value for this attribute.

We were initially intending to treat enable_dhcp as an on-off flag for IPv6.  If it's off, then we won't even bother with the other two attributes.  Because of the issues already being discussed elsewhere in Neutron, you can't assign multiple scopes to a subnet so it's safe to assume that there won't be an IPv4 scope in an IPv6 subnet.

Any possibility we can nail the keywords in the next 12 - 24 hrs? So we can decide the scope in Icehouse release and then, discuss who can do what?
