Cable companies need this amount of address space for
controlling the CPE boxes. The customers still get public
addresses. That's a minimum of two addresses per customer.
One of which can easily be an IPv6 address, so allocating 240/x for this
would seem to cater to those people who can and will modify their
devices to accept 240/4, but cannot or will not give them IPv6 ability.
Large corporations need more than a /8.
A /48 is that, too...
