Most enterprise folks use nowhere near their paltry allotment of IPv4 addresses
because 95% or more of their hosts are on RFC1918 space. Even most companies
with multiple class B legacy allocations use RFC1918 internally and are just
holding the class B's so they can multihome effectively.

Enterprise networks will not be the driver for ISPs to go to IPv6; NAT is too
entrenched. Perhaps greater adoption of always-on broadband access will be the
necessary push.
