  BTW: All of the Canadian providers actually provision addresses statically,
but it is a lot easier to tell Windoz users' to turn on DHCP then to tell
them how to configure their settings. I actually predate DHCP (i.e. the move
from "Rogers Wave" to "Roger Wave@Home"), so actually got the settings
written into the back of my "manual"

  But, one always "autoconfigures" the link-local address, which *is* enough
to do an IGP over, and once you advertise your chunk of addresses, then you
can use the "internal" address for any services on the router itself.
