That's only true if you don't make static DHCP lease available to =
customers
that want static addresses.
You are confusing auto configured addresses with dynamic addresses.
They are not the same thing.

desirable for the address to change at random intervals from the =
customer
perspective? (i.e. why would one want dynamic rather than static auto
configuration?)
