Given that we are looking to do vlan config with Neutron, I think it'd be wise to allocate a very large subnet for this which we can then let Neutron carve it out.

I'm thinking a /16 per DC? (It's a single route to the network controller).

Let's allocate a similar amount of IPs (/20 iirc or thereabouts) as we did in eqiad, but experiment with how to use them with Neutron. I don't think we quite need a /16 at this point. Also, any flexible network model should be able to use multiple smaller ranges as appropriate upon growth, rather than needing one big block. :)
