Agree.
And don't forget that your:
- power company
- communication/entertainment provider/s
- alarm/monitoring company
- local government
- EMS
All have at least discussions in progress that would give each
home/apartment a subnet (albeit possibly/probably on different networks)
for there use as a home service provider.
Take care
Terry

Subject: Re: [ppml] IPv6 addresses really are scarce after all
The definition of a small network is pretty much "single
subnet". Yes, I understand very well that the average home of
the future will have a mixed wiring. Of course, my own home
does have Ethernet and Wi-Fi. In the not so distant future,
it will have several Wi-Fi networks operating on different
frequencies, some form of power-line networking, and some
rooms may have their own high speed wireless wiring using UWB
or some similar technology. But I am pretty much convinced
that all of these will be organized as a single subnet.
You are remarkably trusting. You do all your homebanking on the same
subnet as your teenage children who are studying Hacking 101 in the
privacy of their bedroom? And when guests come over for dinner, you
have
no objection to them taking their laptop to the bathroom in order to
surf for child porn over your wireless network.
The fact is that a lot of people will WANT subnets in the home. They
will want a router/firewall that will isolate each of the children's
bedrooms so that they cannot mess with your bank account or with their
brother's/sister's romantic chat sessions. Many people will want all
wireless access to go through a router. Many will have an in-law
suite,
and want to seamlessly integrate their relative's existing network via
a
simple router connection. And the family jewels, that Raid 5 server
cluster that holds all the family photos and videos, will be behind
another router/firewall. When the kids host a LAN party, the gamers
will
connect to the family network via a router/firewall with limited
Internet access for only the necessary protocols. Subnets multiply for
architectural and security reasons.
Multiple subnets per home is *NOT* a waste of anything. It is an
invitation to dreamers and inventors to make better network things for
the home market. It is an enabler of business activity, an enabler of
competition.
