introduction
Introduction
  • Proposal to change the minimum size of IPv4 delegations to a /24 when the final /8 policy is activated
current problem
Current Problem
  • Current final /8 policy requires networks to meet the requirements for the minimum allocation size currently in place
    • To justify a /22, an immediate need for a /24 must be demonstrated, with a detailed plan for use of a /23 within a year
    • This prevents small networks that are multihomed, operating critical infrastructure, or connecting to IXPs, or running IPv6 transition tools such as NAT64 from justifying a need for IPv4 addresses from the final /8
situation in other rirs
Situation in other RIRs
  • There is no similar policy or proposal in other regions
details of the proposal
Details of the Proposal
  • The minimum delegation size be set to /24
  • The maximum delegation size remains at /22
    • An organisation receiving a /24 under this proposal will be able to request more IPv4 address space until they have received a total of a /22
  • Delegations under the final /8 policy will be extended to include:
    • Small multihoming assignments
    • Internet Exchange Points
    • Critical infrastructure
advantages
Advantages
  • Proposal allows a greater range of networks to access resources in the final /8
  • Extends the maximum possible total of networks benefiting from the final /8 from around 16000 to around 65000
    • Widens the assistance available to networks making the transition from IPv4 to IPv6 over the coming years
disadvantages
Disadvantages
  • No disadvantages are foreseen
impact on apnic members and nirs
Impact on APNIC members and NIRs
  • This proposal impacts all APNIC members
  • This proposal has no direct impact on NIRS, but impacts members of NIRs in the same way it impacts APNIC members
