       Version:   1

       

       Date:      15 July 2008

       

       

       1.  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 /8 in a way

       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-055 in the

       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 /16 in

              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.
