Hi Hytham,
I've heard this comment in several emails the last weeks, and it is
important to correct it.
It is true that for the transition, the ideal situation is to have public
IPv4 addresses, but it is not *absolutely* necessary. We can do the
transition with just private addresses, so please, don't use that anymore as
a rationale for supporting this kind of proposals.
I've tried to explain this very well in a long document which I think is
very descriptive not just about all the exhaustion mitigations but also what
they don't provide, and by contrast, why we need to move to IPv6 even with
private IPv4 addresses. Here is the link so people can read it:

remaining IPv4 address space
Asunto: [sig-policy] رد: prop-051: Global policy for the allocation of the
remaining IPv4 address space
Hi David,
It's great to hear from you..
For the first point: you are right it's fairly small. and I think this point
the RIR teams could reply for it as they have database and statistics which
enable them to know whether these small minority of members are NIR or not..
for my knowledge as we deal here with FLAG, SPRINT, Teleglobe, and others
international carriers which have offices in Egypt, they don't use IP
addresses from AfriNIC.
For the second point: That's a very good question, so we have a debate about
the value of N, what is the suitable value of N? Do you notice that the
modified version of prop-046 (version 2) which have been submitted lately to
APNIC is similar to prop-051 except in the value of N which is 1 . So I
think it's better to leave the value of N to be open for discussion.
However, for me N=5 is suitable specially for Large RIRs like APNIC, RIPE as
from IANA website you can notice that in 2005 APNIC got 3 /8 blocks, in 2006
got another 3 /8 , and in 2007 till now got 5 /8 . And for Ripe in 2005 got
3 /8 , in 2006 got another 3 /8, and in 2007 till now got 4 /8 . For ARIN
in 2005 got 4 /8 and in 2006 got another 4 /8. So the year by year demand
growth is clear and the average is around 3.5 /8 blocks for each RIR which
lead us to expect that N=5 will be suitable to avoid secondary market
specially at the critical time (when IANA announce the IPv4 run-out) when
many will think about selling their IPv4 blocks for money and using NAT. At
that time RIR could face this second market for a time till the market
become stable & almost high percentage of members begin their transition
phase to IPv6.
For the third point: That's the role of Regulator (as I'm working for
Telecom Regulatory Authority), anyone like to establish an ISP (even shell)
company should get a license from TRA and this license is not allowed for
foreign companies (NIR) it's only for Egyptian companies and if as you said
that national large scale ISPs will pay money to become partner of the
existing local ISP , I think it'll be worth for them to pay this money in
upgrading their own network to support IPv6 and avoid the hassle of paper
working for partnership & paying (a lot of) money for other ISP... as it'll
be obvious for local ISPs that this partnership is for IP addresses no more
so they'll ask for more money than they worth to make it..
For the forth point: As i mention in second point that RIRs need time for
market to become stable and know exactly how to deal with that second
market, what policies they need, regulations,...etc. for sure it needs time,
so for helping RIR and its members to find that time ,IMHO, IANA shouldn't
leave RIRs without /8 blocks suddenly !!!
For the fifth point: Ya, we'll need IPv6-to-IPv4 gateways and vice versa. So
we do still need IPv4.. which means we couldn't say for new comers in the
following three years we don't have IPv4 for you, go and use IPv6 only !!!
they will live in isolated islands.. It's the role of RIR to plan how to
afford IPv4 in the next years and this proposal is aiming to help in that if
it get consensus..
I'd like to thank you for your care and following up the discussion.
Cooperation between all RIRs regarding this situation of course will have
its good impact on all Internet users all over the world.
Thanks & Best Regards,
Haitham..

Hi,
Sorry for the slow response.

Probably fairly small. However, it is probably worth noting that the
majority of address space at the RIRs is consumed by a small minority
of the members.

Why do you think 5 /8s for each RIR will avoid a secondary market?

I am not fully aware of the situation in Africa (nor in Latin America
and the Caribbean), but I would be surprised to find that there
aren't countries in which it is possible to establish shell companies
that do little more than establish a legal presence in that country.
Further, it doesn't even have to be a shell, it could as easily be a
partnership with an existing company, including an established ISP.
All it takes is a bit of money, which large scale ISPs generally have.

No, I wouldn't consider it fair. However, from the perspective of
the large scale ISPs, it is just business. In any event, the point
I've been trying to make is that regardless of what the RIRs do, a
secondary market will almost certainly establish itself and it would
probably be best for the RIRs to figure out how to deal with that
fact rather than pretending business realities don't apply.

Given IPv6 is not backwards compatible with IPv4, you'll need some
form of network address translation to allow folks who are IPv4-only
to talk to sites that are IPv6-only and vice versa. The future is
_full_ of some form of NAT.
