policy proposal 'Use of final /8' has been sent to the Policy SIG for
review. It will be presented at the Policy SIG at APNIC The
proposal's history can be found at:
http://www.apnic.net/policy/proposals/prop-062-v001.html We
invite you to review and comment on the proposal on the mailing list
before the meeting. The
comment period on the mailing list before an APNIC meeting is an important
part of the policy development process. We encourage you to express
your views on the proposal:
- Do you support or oppose this proposal?
- Does this proposal solve a problem you are experiencing? If so,
tell the community about your situation.
- Do you see any disadvantages in this proposal?
- Is there anything in the proposal that is not clear?
- What changes could be made to this proposal to make it more
effective? randy

Introduction ---------------- This
proposal describes how APNIC should handle the final /8 which would
be allocated to it by the IANA under a successful implementation of
prop-055, "Global policy for the allocation of the remaining IPv4 address
space" [1]. The
proposal seeks to ensure that new and existing LIRs can receive a minimum
amount of IPv4 address space to assist with their participation
in the Internet industry as the industry transitions to using
the IPv6 protocol over the next few years. 2.
Summary of current problem ------------------------------ The
IANA IPv4 address pool is diminishing rapidly. If prop-055 is implemented
globally, each RIR will receive a /8 to be used once the remaining
IANA IPv4 pool has been depleted. One of the goals of prop-055
was that each RIR could then use its allocated / that
suits the individual needs of its community. In
APNIC's case, the intention of the proposal's authors is to use the final
/8 to reduce the surprise incurred by new LIRs during the transition
from the IPv4 to IPv6 protocol. The
Internet will still use IPv4 for several years during the adoption of
IPv6. During this period new LIRs will need to participate in the IPv4
Internet while they deploy services using the IPv6 Internet. Inability
to participate directly in the IPv4 Internet inhibits new LIRs'
ability to provide service. If this were to happen, new LIRs would
have to resort to address translation devices to map the private IPv4
address space they use into the public address space received from
their upstream providers. Existing
APNIC policy regarding the distribution of IPv4 address space makes
no allowance for IPv4 allocations to new LIRs after the IANA pool
is exhausted. Without
any particular policy for this address block, APNIC's normal IPv4
allocation rules would apply. It is quite feasible, for example, that
one organisation could consume the entire final /8 address block delegated
to APNIC by IANA, negating the purpose and considerable effort
that has gone into gaining global consensus for prop first
place. This
policy proposal seeks to address that problem. 3.
Situation in other RIRs --------------------------- As
far as is known, there is no similar policy either being proposed or
implemented at any of the other RIRs but we would like to recommend that
they consider analogous proposals. This
policy proposal applies to the APNIC service region only. It is highly
likely that similar policy proposals will be made in other RIR regions
also. It
should be noted that at the recent LACNIC XI meeting, consensus was reached
on the following policy proposal:
LAC-2008-04: Special IPv4 Allocations/Assignments Reserved for New
Members
www.lacnic.net/documentos/politicas/LAC-2008-04-propuesta-en.pdf Under
the LACNIC proposal, when there is no more IPv4 address space in the
IANA free pool, LACNIC will reserve a /12 out of their remaining pool.
>From this /12, LACNIC will allocate /22s to new LIRs and assign /24s
to critical infrastructure. 4.
Details of the proposal --------------------------- This
proposal describing the distribution of the final /8 has three parts: 4.1
New LIRs
It is proposed that each new LIR receive IPv4 addresses which they
can use for supporting legacy IPv4 services to ensure their full
presence on the IPv4 Internet during the transition phase to IPv6:
- Each new LIR may receive exactly one /22 (1024 routable IPv4
addresses), APNIC's current minimum allocation size. If
APNIC's current minimum allocation were to reduce in size in
future, the allocation made under this policy should also be
reduced to match.
- Each new LIR may receive the specified allocation size
regardless of LIR size or intended membership tier.
- New LIRs may apply for and receive this allocation once they
meet the criteria to receive IPv4 address space according to
APNIC's allocation policy in force at the time (currently
documented in [APNIC-86]).
A new LIR in this proposal is defined as being an organisation
which has recently become a full member of APNIC or a full member
of one of APNIC's NIRs but has yet to be assigned or allocated any
IPv4 address space.
Membership of APNIC as an LIR is determined by APNIC's membership
criteria at the time of application. Membership of an APNIC NIR
is determined by each individual NIR's membership criteria at the
time of application. 4.2
Existing LIRs
It is proposed that each existing LIR may request and receive only
a single allocation from the remaining /8:
- Each existing LIR may receive exactly one /22, APNIC's
current minimum allocation. If APNIC's current minimum
allocation were to reduce in size in future, the allocation
made under this policy should also be reduced to match.
- Each existing LIR may receive the specified allocation size
regardless of size or intended membership tier
- Each existing LIR may apply for and receive this allocation
once they meet the criteria to receive IPv4 address space
according to APNIC's current allocation policy in force at
the time (currently documented in [APNIC-86]).
This ensures that each existing LIR receives 1024 routable IPv4
addresses which they can use for supporting legacy IPv4 services
during the transition phase to IPv6.
An existing LIR in this proposal is defined as being an
organisation which is a full member of APNIC or a full member of
one of APNIC's NIRs and has already been assigned or allocated
IPv4 address space.
Membership of APNIC as an LIR is determined by APNIC's membership
criteria at the time of application. Membership of an APNIC NIR
is determined by each individual NIR's membership criteria at the
time of application. 4.3
Unforeseen circumstances
It is proposed that:
- A /16 is held in reserve for some future uses, as yet
unforeseen.
The Internet is a disruptive technology and we cannot predict
what might happen. Therefore it is prudent to keep a /
reserve, just in case some future requirement makes a demand of
it.
- In the event that this /16 remains unused in the time the
remaining /8 covered by this policy proposal has been allocated
to LIRs, it returns to the pool to be distributed as per clauses
4.1 and 4.2. 5.
Advantages and disadvantages of the proposal ------------------------------------------------ 5.1
Advantages
- APNIC's final /8 will have a special policy applicable to it.
This avoids the risk of one or a few organisations consuming the
entire block with a well crafted and fully justified resource
application.
- The proposal ultimately allows for 16384 LIRs (both new and
existing) to receive exactly one /22 each.
This is substantially larger than the existing APNIC membership,
and attempts to ensure that no organisation lacks real routable
IPv4 address space during the coming transition to IPv6. 5.2
Disadvantages
- Some organisations may believe and can demonstrate that their
IPv4 requirements are larger than a /22.
But this final /8 is not intended as a solution to the growth
needs of a few organisations, but for assisting with the
transition from IPv4 to IPv6.
- Some organisations may set up multiple LIR registrations in an
effort to get more address space than proposed.
APNIC must be vigilant regarding these, but the authors accept
that it is hard to ensure complete compliance. With 16384
possible allocations being proposed, this is not envisaged to be
a major problem. 6.
Effect on APNIC members --------------------------- This
proposal allows APNIC LIRs (existing and new) to receive address space
from the final /8 allocated to APNIC under prop-055. 7.
Effect on NIRs ------------------ This
proposal has no direct impact on the operation of the NIRs, but as
noted in the text above, has direct impact on the ability of NIR members
(existing and new) to receive address space from the final /8 allocated
to APNIC under prop-055. 8.
