First, allow me to apologize for posting bogus numbers; I forgot to
change the base and the increment. Below at the end are pasted the right
numbers.

I am not using countries as a delimiter for network design. What we are
talking about here is allocation from the root to RIRs. Each RIR would
be delegated a set of countries like today, and RIRs would assign
prefixes to LIRs like today as well.
The changes this induces for LIRs are:
For small LIRs, this changes nothing. For medium LIRs, they might have a
few prefixes instead of a single one. For large LIRs, it does mean a
large number of prefixes to deal with in the short term, but not that
big of a deal in the long run as a large LIR present in dozen of
countries will need more than one /32 anyway.

I would say a few generations. And then what? We'll have a few more
prefixes than what would be really needed.

There is ample room for new countries.

It does not really matter, at least not for political reasons. The
reason there are zones is to provide a higher level of aggregation than
the country and also to provide some unused space. If you don't like the
cutout, feel free to propose one.
> Last time I checked, Hawaii was still part of the USA.
This was a voluntary decision given the unique geographical situation of
Hawaii. Most other islands that are thousand of miles away from the
mainland got promoted to the status of "country", look in the Central
America zone there is a country called Netherland Antilles for example.
This makes sense as obviously the fiber plant for these islands has
nothing to do with the mainland they depend on.

Me neither. Remember that we are talking PA space here. This system is
compatible with multihoming systems that use PI identifiers _and_ PA
locators at the same time.

Agree, what is your point here?

Agree too, what does my proposal change to these regards?

These are year 2000 numbers and they should not be (they should be a
future projection some years down the road). I could not find a public
data set with a projection for free. If this was to go real, I would
need a better data set; however for the sake of the example these
numbers are good enough.
> I assume it has to do with GDP
Nope. These numbers are population only, so it considers that Ethiopia
is granted the same numbers of IPv6 addresses than silicon valley per
capita.

There are census numbers adjusted by predicted short-term growth as
census are not taken in every country the same year. It means that for
some countries the number might be actual 2000 census data while for
other countries the numbers might be 1990 census data individually
extrapolated to 2000.

They took it away unfortunately and I can't find a cache.

It's politically impossible to assign socio-economic factors such as
wealth. Who am I to pick a number and decide that Ethiopia gets 16 times
less addresses that the US? If it is true that in the short term it
would work, this would generate endless debates, which is why I picked
that an Ethiopian gets the same number of IP addresses than an American.

The general rule is that a multinational enterprise will obtain address
space from the LIR that provides services to it in each country.
Example: Enterprise Acme is present in 4 countries. In the Netherlands
it receives connectivity from LIR A and LIR B. In France it receives
connectivity from LIR C. In Japan it receives connectivity from LIR A
and LIR D. It gets 5 /48s:
Netherlands: - from LIR A's Netherland block
- from LIR B's Netherland block
France: - from LIC C's France block
Japan: - from LIR A's Japan block
- from LIR D's Japan block
Also, it is clear that LIR A is a large multinational LIR so it has a
/32 for the Netherlands and a /32 for Japan.
Hope this answers the question, if not please be more specific.

I would say yes (doing otherwise would break the geographical
aggregation we are discussing). In reality, this never happens though. A
LIR does not pack their bags on a Friday evening, put the M160 in the
plane and deploy the next day in another country. What happens is that
the new network is deployed before the old one is taken down (in the
real world with in-house spares :-( and that the two address blocks
would be active at the same time, then if the LIR really completely
moves out of a country the old block should be given back to the RIR.

Of course, a small LIR still needs a /32.

Then explain me how you achieve Gert's goal?

I don't know how to parse this? All RIRs have the concept of LIR?
