OK, I've been watching this thread with great interest, and I still
don't understand well enough to know the answer:

Well, the practicallity of NAT is that it allows you to bridge other networks
to the internet, which themselves ain't part of it. This might be interesting

if you want to hide your own network structure, especially if you may only
your uplink for one computer or if your own network is a playground and you
don't want to interfere with the rest, but maybe need some limited
connectivity to it.

With all the detailed discussion between the Big Guys and their
concerns, I still haven't been able to understand whether or how ipv6
handles my situation:

My home network is based on a wifi/router/firewall. I buy one line from
Cox. As I understand it, more IP addresses would cost correspondingly
more; I know this was true for my previous IP.

So it's very convenient for me to buy one address, connect my Netgear to
it, and use dhcp for the half-dozen devices I have in my home. Since
198.162.x.x addresses cannot pass through a router, my network is
private, and the firewall, set up to ignore all attempts at external
access, makes me invisible to the Internet unless one of my computers
initiates a transaction.

How does ipv6 handle this?
