When a hosting company assigns addresses to a newly provisioned VPS
its every bit as automatic. And every bit as ephemeral: the customer
may cancel in hours, days or years just as your DSL customer will hold
an address (not necessarily that particular one) for the same period
of time. Yet they're supposed to report that customer's identity in
support of their address request while your DSL customer skates by

And is your DSL pool at all sticky, waiting a little while for the
same MAC to present again before releasing the address?

Double standard my friend.
