Utility companies utilize Zigbee pretty extensively. So that's
millions and millions of addresses right there.

Really.... we don't have enough debates going on in this thread?
Those little gadgets can very happily live within a link-local only
network, or isolated private network.
Exactly. Behind the utilities (closely monitored and highly restrictive)
firewall. Most likely behind multiple firewalls. (border fw, internal
operations fw, monitoring network firewall). No reason they shouldn't
have a fully routeable address.
I know the subject of "nat" in IPv6 will have people chasing me with
pitchforks, but there are a lot of things in the world that don't need
to be accessable by the entire world and should be (must be) protected
from even accidentally being exposed to the Evil Internet(tm). Everyone
will chime in with "firewall them", but the risk exists as long as they
have global addresses. Having to break into a machine in order to get
at the internal network (ala today's NAT) makes the network much safer
-- not "safe", but safer than directly naked on the internet.
This is no different then having machines with a public IP on the net
today. A firewall is such a small part of an overall security architecture.
Don't troll.
