Transcript of "I Pv4exh Lacnicx 20070523"

  1. 1. 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
  2. 2. Introduction <ul><li>This proposal is : </li></ul><ul><ul><li>to respond in an orderly way to the upcoming exhaustion of the IPv4 free address space. </li></ul></ul><ul><ul><li>to ensure that LIRs can receive IPv4 address allocation until pre-determined date (T-date). </li></ul></ul><ul><li>This proposal does not : </li></ul><ul><ul><li>intend to artificially drive up IPv4 addresses </li></ul></ul><ul><ul><li>promote IPv6 </li></ul></ul>
  3. 3. 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)
  4. 4. Current Problems <ul><li>The final date of IPv4 allocations is ambiguous </li></ul><ul><ul><li>LIRs do not consider IPv4 address exhaustion as an imminent issue </li></ul></ul><ul><ul><li>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) </li></ul></ul><ul><ul><li>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 </li></ul></ul>
  5. 5. Proposal principles <ul><li>Global Synchronization </li></ul><ul><li>Set and announce the date when the IPv4 allocation is terminated </li></ul><ul><li>Not change the current address policy for the extension of IPv4 address lifetime </li></ul><ul><li>Separate discussions on “recycle” issue </li></ul>
  6. 6. Proposal principles (cont.) <ul><li>Global Synchronization </li></ul><ul><ul><li>All 5 RIRs should proceed at the same time for measures on IPv4 address exhaustion </li></ul></ul><ul><ul><li>Ensuring fairness across the regions </li></ul></ul><ul><ul><li>Prevent confusion such as an attempt to receive allocations from an RIR outside their region </li></ul></ul><ul><li>Set and announce the date when the IPv4 allocation is terminated </li></ul><ul><ul><li>To ensure all LIRs/ISPs can receive IPv4 allocation until such date </li></ul></ul><ul><ul><li>Also, to give time to LIRs/ISPs to prepare for the network re-configuration (Large-scale-NAT, IPv6, or other technical solution) </li></ul></ul>
  7. 7. Proposal principles (cont.) <ul><li>Not change the current address policy for the extension of IPv4 address lifetime </li></ul><ul><ul><li>Making large changes in the current policy towards conservation is difficult in reality </li></ul></ul><ul><li>Separate discussions on “recycle” issue </li></ul><ul><ul><li>Recovery of unused address space is very important and should be addressed, but should not be tied with this proposed policy </li></ul></ul>
  8. 8. Details of the proposal <ul><li>Announce the day in which the IANA pool becomes less than 30*/8 (A-Date) </li></ul><ul><li>Terminate new allocation/assignment from RIR on the day (T-Date) exactly 2 years after A-Date </li></ul>(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
  9. 9. Benefits <ul><li>Final date of IPv4 allocation is clearly demonstrated well in advance (2 years) </li></ul><ul><ul><li>LIRs and users can prepare for the exhaustion (subsequent allocation, renumbering, business plan, IPv6 etc.) </li></ul></ul><ul><ul><li>RIRs can make the last allocation and avoid causing feelings of unfairness among LIRs </li></ul></ul>
  10. 10. Discussion in APNIC <ul><li>Consensus reached: </li></ul><ul><ul><li>Global Synchronization </li></ul></ul><ul><ul><li>Not change the current address policy for the extension of IPv4 address lifetime </li></ul></ul><ul><ul><li>Separate discussions on “recycle” issue </li></ul></ul><ul><li>Consensus NOT reached: </li></ul><ul><ul><li>Set and announce the date when the IPv4 allocation is terminated </li></ul></ul><ul><ul><ul><li>Back to ML for further discussion </li></ul></ul></ul>
  11. 11. Discussion in ARIN <ul><li>Public Policy Meeting resulted in few in favor(4/93) and many against(47/93) </li></ul><ul><li>Broad comments on this policy… </li></ul><ul><ul><li>Inappropriate action </li></ul></ul><ul><ul><ul><li>Artificial measures to move IPv6 </li></ul></ul></ul><ul><ul><ul><li>Anti-trust issue - Denial of Service by the dominant supplier </li></ul></ul></ul><ul><ul><ul><li>It is enough if Community stays informed of size of remained space </li></ul></ul></ul><ul><ul><li>Influence by the exhaustion </li></ul></ul><ul><ul><ul><li>Issue of reclaiming the unused legacy space </li></ul></ul></ul><ul><ul><ul><li>Emergence of trade market </li></ul></ul></ul>
  12. 12. Other RIRs <ul><li>RIPE NCC </li></ul><ul><ul><li>Introduced in RIPE 54 (May 2007) </li></ul></ul><ul><ul><li>Back to ML for further discussion </li></ul></ul><ul><li>AfriNIC </li></ul><ul><ul><li>Introduced in AfriNIC 6 (May 2007) </li></ul></ul><ul><ul><li>Informational presentation with no decision </li></ul></ul>
