There was a question during my summit session on Friday at 4:00 about providing diagrams. There are diagrams in the specification [2] that show where IP addresses are used in the various external network schemes. The first diagram, almost half-way down, shows the current method which uses public IP addresses for everything. The public IP space is represented by the 203.0.113.0/24 range, a range reserved for documentation.
Compare that diagram to the next one which substitutes some of the public IP addresses for private in the 100.64.0.0/24 range. This range comes from 100.64.0.0/10 which is a private space allocated for use on provider networks [3]. It is a great fit for this application because its stated purpose makes it unfit for tenant networks but perfect for a cloud provider to use under the hood. The diagrams get a bit more complicated from there. The next two highlight the new floating IP namespace that the DVR implementation uses. Please review the specification in gerrit [1] and let me know if something is not clear in the document.
