    • IPv4 Countdown Policy Proposal (LAC-2007-09) Toshiyuki Hosaka <hosaka@nic.ad.jp> Working Group on the policy for IPv4 address exhaustion, Japan Network Information Center (JPNIC) May 23, 2007 LACNIC-X, Isla Margarita, Venezuela
    • Introduction
      • This proposal is :
        • to respond in an orderly way to the upcoming exhaustion of the IPv4 free address space.
        • to ensure that LIRs can receive IPv4 address allocation until pre-determined date (T-date).
      • This proposal does not :
        • intend to artificially drive up IPv4 addresses
        • promote IPv6
    • How much IPv4 address left? Source : Geoff Huston - IPv4 address space report http://www.potaroo.net/tools/ipv4/ RIR pool IANA pool 48 /8s left 2010 March 2010 Nov. Actual record Projection Consumption rate : 2004 : 9 * /8 2005 : 13 * /8 2006 : 10 * /8 2007 : 7 * /8 (As of 2007.4.16)
    • Current Problems
      • The final date of IPv4 allocations is ambiguous
        • LIRs do not consider IPv4 address exhaustion as an imminent issue
        • They will face confusions such as re-addressing their network or making subsequent requests at the last minute within a limited time (last minutes rush)
        • LIRs will be forced to build networks with a big architectural change either with hierarchical NAT or with IPv6, or even with another solution in a very short timeframe
    • Proposal principles
      • Global Synchronization
      • Set and announce the date when the IPv4 allocation is terminated
      • Not change the current address policy for the extension of IPv4 address lifetime
      • Separate discussions on “recycle” issue
    • Proposal principles (cont.)
      • Global Synchronization
        • All 5 RIRs should proceed at the same time for measures on IPv4 address exhaustion
        • Ensuring fairness across the regions
        • Prevent confusion such as an attempt to receive allocations from an RIR outside their region
      • Set and announce the date when the IPv4 allocation is terminated
        • To ensure all LIRs/ISPs can receive IPv4 allocation until such date
        • Also, to give time to LIRs/ISPs to prepare for the network re-configuration (Large-scale-NAT, IPv6, or other technical solution)
    • Proposal principles (cont.)
      • Not change the current address policy for the extension of IPv4 address lifetime
        • Making large changes in the current policy towards conservation is difficult in reality
      • Separate discussions on “recycle” issue
        • Recovery of unused address space is very important and should be addressed, but should not be tied with this proposed policy
    • Details of the proposal
      • Announce the day in which the IANA pool becomes less than 30*/8 (A-Date)
      • Terminate new allocation/assignment from RIR on the day (T-Date) exactly 2 years after A-Date
      (Now) (A-Date) (T-date) 2 years No new allocation/assignment Allocation/assignment based on current policy IANA pool got less than 30* /8 Some /8 IANA pool may be left
    • Benefits
      • Final date of IPv4 allocation is clearly demonstrated well in advance (2 years)
        • LIRs and users can prepare for the exhaustion (subsequent allocation, renumbering, business plan, IPv6 etc.)
        • RIRs can make the last allocation and avoid causing feelings of unfairness among LIRs
    • Discussion in APNIC
      • Consensus reached:
        • Global Synchronization
        • Not change the current address policy for the extension of IPv4 address lifetime
        • Separate discussions on “recycle” issue
      • Consensus NOT reached:
        • Set and announce the date when the IPv4 allocation is terminated
          • Back to ML for further discussion
    • Discussion in ARIN
      • Public Policy Meeting resulted in few in favor(4/93) and many against(47/93)
      • Broad comments on this policy…
        • Inappropriate action
          • Artificial measures to move IPv6
          • Anti-trust issue - Denial of Service by the dominant supplier
          • It is enough if Community stays informed of size of remained space
        • Influence by the exhaustion
          • Issue of reclaiming the unused legacy space
          • Emergence of trade market
    • Other RIRs
      • RIPE NCC
        • Introduced in RIPE 54 (May 2007)
        • Back to ML for further discussion
      • AfriNIC
        • Introduced in AfriNIC 6 (May 2007)
        • Informational presentation with no decision
    • Gracias!
