On circuits that assign an IP with DHCP, it is bound to its MAC address.
My ISP, for one, will assign multiple IP's to different MAC addresses on
the same circuit, to a point. That many zeros are not likely to pass
validation. The stock firmware increments the Ethernet MAC to get the
ATM one, which is clearly a sane thing for a DSL router to do.
