1. IPv6: Getting Addresses, Differences from IPv4 30 November 2010 7 IPv4 /8s Remaining

About IPv4 and IPv6 IP versionIPv4IPv6 Deployed 19811999 Address Size 32-bit number128-bit number Address Format Dotted Decimal Notation: 192.0.2.76 Hexadecimal Notation: 2001:0DB8:0234:AB00: 0123:4567:8901:ABCD Number of Addresses 2 32 = 4,294,967,2962 128 = 340,282,366,920,938,463, 463,374,607,431,768,211,456 Examples of Prefix Notation 192.0.2.0/24 10/8 (a /8 block = 1/256 th of total IPv4 address space = 2 24 = 16,777,216 addresses) 2001:0DB8:0234::/48 2600:0000::/12

4. IPv4 Address Space Utilization * as of 30 November 2010 4

5. Available IPv4 Space in /8s 5 In 2010, RIRs have been allocated nineteen /8 blocks as of 30 November, leaving seven /8s unallocated (7/256 - 2.73%).

6. IPv4 Depletion Situation Report There are 7 /8s remaining in the IANA pool as of 30 November 2010. Demand for IPv4 continues to grow from organizations around the world. Once IANA free pool depletes, ARINs inventory will deplete anywhere from days to months.

7. What about underutilized blocks? ARIN actively attempts reclamations We have reclaimed large underutilized blocks and will continue Our successes will not significantly extend the lifetime of the IPv4 free pool

8. What if? Current demand globally is ~24 Million IP addresses per month What if we have all IPv4 unicast to start over – Counting /32s it would take ~ 12 years to fully re- deplete the IPv4 resource What if we have all of IPv6 to start (we do) – Counting /64 subnets it would take ~ 768 Billion years to deplete the resource – Counting /48 subnets it would take ~ 11.7 Million years to deplete the resource

9. IPv4 Registration Transfers Long standing merger & acquisitions transfer policy remains New policy: Transfers to specified recipients (8.3 of NRPM)

10. 8.3 Transfer Policy In addition to transfers under section 8.2, IPv4 number resources within the ARIN region may be released to ARIN by the authorized resource holder, in whole or in part, for transfer to another specified organizational recipient. Such transferred number resources may only be received under RSA by organizations that are within the ARIN region and can demonstrate the need for such resources, as a single aggregate, in the exact amount which they can justify under current ARIN policies.

11. IPv4 /10 Dedicated for IPv6 Deployment ARIN will set aside a /10 from our last /8 from IANA Allocations are for IPv6 transition only Allocation sizes: /28 minimum - /24 maximum

12. IPv4 /24s are back! Only for multi-homed end-users Must still show at least 25% used immediately and at least 50% used within one year NRPM 4.3.6.2

13. IPv6 Policies ISPs – Known, existing ISPs automatically qualify – /32 minimum Really really really big; ~4.2 Billion subnets End-users – Typically qualify by showing you qualify for IPv4 – /48 minimum 65,536 subnets Qualify for larger by showing proposed use – Guidelines: /48 for a large site, /56 for a small site

14. IPv4 & IPv6 - The Bottom Line Were running out of IPv4 address space. New demand surge could quickly deplete remaining IPv4 IPv6 must be adopted for continued Internet growth. We must maintain IPv4 and IPv6 simultaneously for many years. IPv6 deployment has begun.

15. RIRs have been allocating IPv6 address space since 1999. Thousands of organizations have received an IPv6 allocation to date. ARIN has IPv6 distribution policies for service providers, community networks, and end-user organizations. IPv6 Deployment has begun
