Dynamic assigned addresses mean that the BRAS the customer terminates on
can hand out a range out of a pool assigned to it. This means I can
have a single route in my routing table for a whole BRAS (maybe 20k
customers) vs 20k routes and associated processing when the dsl goes
up/down/etc.

My car is designed to go 200km/hr or more. But the roads are
implemented poorly. IPv6 is design to do everything for everyone, but
the reality is the implementations aren't there or it's not practical.
Mobile just creates more mess, I'm trying to make this simple and make
it work.
