Why? They have to have a table mapping (IP) address to (home) address,
so why does it matter if the IP address is theirs?
++++++++++++++++++++++++++
If they don't go directly to the home, they will constantly be:
- Unable to connect due home firewall/network changes
- Have to deal with an IP churn rate per home that will force them to
change approaching 20% of their entries annually because someone either
moves or change service providers.
- Will have to require their customers ALSO get an ISP to get load
control service.

I'm trying to understand your position: The power company needs to
build its own IP network in order to manage power systems at each
home; their IP address assignments will be from their aggregatable
block.

I would be surprised. IP addresses are not property, and are not
transferable in that sense.
++++++++++++++++++++++++++
We will see how it develops. My guess is that EMS will win although
with IP-v6 they could certainly allocate the address portion of the
space themselves to the property permanently and allow the network
portion to change.

Would a /64 be sufficient for each, do you think? Especially if
they're not from a single aggregate block, this would be important
to understand.
+++++++++++++++++++++++++++
I would certainly think so.

This is the place to fight for that, not Capitol Hill.

Just to make sure I understand your position:
You'd rather have nine provider aggregated addresses (counting networks
above) than one (PI or PA) address?
+++++++++++++++++++++++++++++
I think that is what will happen. Whether I care or not depends on how
well they can hide the details. Regardless which option wins, we cannot
expect the average homeowner to be able to deal IP networking detail at
this level.
+++++++++++++++++++++++++++++
There are some differences here. Your choice of local phone carriers
has been extremely limited. The local carrier has physical facilities
to your house; now the cable company and power company also have
facilities. An ISP provides a service using those facilities. They
may provide multiple services, including routing (pretty essential, and
requiring aggregatable addressing) and maybe also email, but these are
disjoint: there's no reason your Internet access provider has to be your
email provider.
+++++++++++++++++++++++++++++
Agreed but what we have to do is figure out how to provide the homeowner
at stable set of logical addresses (email/web/voice/etc) that map their
physical ones. Otherwise I am certain that local government will win
here.
+++++++++++++++++++++++++++++
> This is exactly why I would prefer a local government provided IP that

I must have misunderstood your previous points then. There are a lot
of points to take away from this sentence:
1. "Local" government meaning city, county, state, federal, or some
kind of regional Internet registry?
+++++++++++++++++++++++++++++++++
The first four although the fifth could work.
+++++++++++++++++++++++++++++++++
2. You want a government authority to replace the current system of IP
address allocation? Can you outline the ways in which this is superior
to the current system?
++++++++++++++++++++++++++++++++++
NO, but that is what I will probably get. The reason is simple; they
can provide me with a stable set of logical relationships that map to my
physical home. A present this is simply not possible for a service
provider to do.
+++++++++++++++++++++++++++++++++++
3. How would IP addresses be "associated with my home address"?
Do you envision embedding physical address information in the IP
address, like GPS coordinates, or a database owned and operated by the
government?
+++++++++++++++++++++++++++++++++++
I think that either GPS or a government DB is most likely.
+++++++++++++++++++++++++++++++++++
4. How would routing work? Would every network have to carry a
Separate route for every home? Or do you mean that local governments
should take over all Internet access?
++++++++++++++++++++++++++++++++++++
In the scenario I envision occurring, local government just becomes
another "service provider" and each of the home service providers does
their own routing.

That's fair to say. I don't quite understand whether you favor
competition, monopolization, or nationalization. I'm hoping you can
clarify how routing might work in your vision. I definitely advise
you to take advantage of one of the many companies providing free
email, so that you don't have to go through the pain of updating your
contacts next time you switch ISPs. Or you can set up your own mail
server, of course.
+++++++++++++++++++++++++++++++++++++
I'm in favor of a solution that provides the home owner or individual
with a set of "stable" logical relationships. I certainly won't go
through a "free email provider" as I need them to both be around for the
long term and to be responsible. As an example, I keep paying MSN
monthly even though I have no used them as an ISP for over five years;
this is simply to provide my wife a stable email for a large non-profit
group she works with. It is that important!
