The models I listed are typical to an operator that runs its
own infrastructure (including the FTTH last mile), and does
not necessarily wholesale out to other operators.
I've seen certain countries that have given the incumbents
leeway to wholesale at the IP level, which the incumbent
likes because they "perceive" more control than if they had
to hand-off Layer 2 wholesale. In such cases, VRF's and/or
logical routers have been deployed.

Agree. DHCP really is the way to go, now. Plus, there is
good support for IPv6 with vendors today re: DHCP-based
