I think every device owned by a single person deserves a 
public IP address. Whether that is the case or not depends 
on user and network preference.

We can't imagine that actual people will need IP addresses 
today. But maybe that could be the case in future, we just 
don't know. And that's why I keep saying that we should be 
more conservative about how IPv6 space is allocated and 
assigned, but that's a topic for another day.

Sounds like a bug, try upgrading.

Agree, but it's still in wide use, mostly because ISP's 
can't offer their customers local connectivity.
