[ppml] IP-v6 Needs (RE: a modified proposal 2005-8)

[Davis, Terry L]

Lee

My main point is that we cannot plan for an IP-v6 world using IP-v4
templates.  The key messages:

1) We MUST provider users (individuals/government/business) with logical
stability.  Getting new IP addresses, DNS names, and email addresses
every time we either change providers or move will simply be
unacceptable.  Without this logical stability, every communication
service (voice/email/etc) is unstable, industry-wide initiatives (i.e.
like power control) are not possible, and even gains the financial
institutions hope to make with EFT systems become limited (i.e. remember
the fun of resetting all your automatic billings/payments email
addresses last time you changed service providers?).  I know this may be
more an IETF issue but I'm there next week.

2) Assuming that any users (individuals/government/business) will have a
single service provider is completely unrealistic.  (Much of point in
the chain below) We need to understand impacts of this to IP-v6 network
architectures and routing.

(I'm already dealing with this reality in the aviation industry as we
plan for IP-v6.  The aircraft MUST be able to join to many different
service provider networks as it moves around the world; we have carriers
that fly there aircraft literally around the world in a bit over a day.
The aircraft WILL most of the time have simultaneous links to multiple
service providers.  An aircraft will probably have at least three
separate networks onboard: air traffic control, airline or operator, and
in-flight passenger services/entertainment.)

3) Besides government, whole industries will want address blocks that
they manage as closed network; these may be at the regional, national,
or global level.  Power, shipping, and aviation are some that will
almost certainly require this.

4) We might as well come to terms with the idea that some of these must
be essentially irrevocable.  Can anyone envision revoking the IP address
of an aircraft that is set up in air traffic control systems around the
world?

I doubt that I can make the ARIN meeting in Montreal but I will try.

Take care
Terry

That does make it challenging to respond.  In my responses below,
I'm trying to point out that this is where we set IP address
allocation policies, and in order for your participation to be
effective, you need to describe what policy you would like to see.

I understand 1 and 3, but I don't follow your middle point.  You
suggested government assignment, either to a physical address, in
which case there's no churn, or to an owner, in which case the
churn would happen anyway due to moves, regardless of whether the
address was assigned by utility or government.

EMS will win what?  I didn't know there was a contest.  

IP addresses are not property.  They are identifying numbers, which
are allocated or assigned based on policies created by the public
and administered by the Regional Internet Registries, such as ARIN.
They are fungible, and cannot be owned, bought or sold.

What do you want to have happen?
Can you explain how one plan or another affects homeowners?

Again, win what?
Since ARIN only administers IP addresses, can we discuss those
separately?  

Is it necessary for email address, web site, and phone number
to be permanently mapped to an IP address?  Are no dynamic
mappings possible which might make the IP address transparent
to the homeowner?

In order to derive a policy, we need more detail.  What do you

Is that what you want?
Can you provide a way of embedding GPS coordinates into IPv6 addresses?
Does it scale?

Can you describe such a government database?  Maintainer, schema,
etc.  

How would either of these be routed?

I'm not quite sure I followed that.  The local government becomes the
Internet access provider?  Or do they provide some other service?

If the government assigns an address to be used by all of the other
providers, there are significant routing implications.  If there's
any competition, then addresses cannot be aggregated, and a separate
routing entry will have to be maintained for each address.  Can you
describe how that would scale, given even optimistic technology
projections?  If there's no competition, then we have nine completely
separate networks, which do not overlap anywhere and cannot inter-
connect.  Also, a different form of government and economy.

If I have correctly interpreted your arguments, you advocate
government control of networks and centralized, rigidly hierarchical
networks which map exactly to geography.  You also want those networks
to map exactly to individuals, which seems to be a conflict.
Perhaps smooth dynamic mappings between identifiers would require 
fewer fundamental changes to TCP/IP.
