  1. APNIC Policy Update 1st TWNIC IP Open Policy Meeting 3 December, 2003 Taipei, Taiwan

  2. Internet Registry Allocation and Assignment Policies

  3. Policies Overview of APNIC policies • Definitions • Background • Objectives • Environment • Allocation & Assignment Policies

  4. Policies Allocation and Assignment Allocation “A block of address space held by an IR (or downstream ISP) for subsequent allocation or assignment” • Not yet used to address any networks Assignment “A block of address space used to address an operational network” • May be provided to LIR customers, or used for an LIR’s infrastructure (‘self-assignment’)

  5. Policies /8 APNIC Allocation /20 /22 Member Allocation Sub-Allocation /27 /26 /26 /25 /24 Allocation and Assignment APNICAllocatesto APNIC Member APNIC Member Assignsto end-user Allocatesto downstream DownstreamAssignsto end-user Customer / End User Customer Assignments

  6. Policies Portable & non-portable Portable Assignments • Customer addresses independent from ISP • Keeps addresses when changing ISP • Bad for size of routing tables • Bad for QoS: routes may be filtered, flap-dampened Non-portable Assignments • Customer uses ISP’s address space • Must renumber if changing ISP • Only way to effectively scale the Internet  

  7. Policies /8 /8 APNIC Allocation APNIC Allocation /20 Member Allocation Allocated Portable /22 Sub-allocation Allocated Non-Portable Assignment /26 /25 Assignment Assignment /26 Assigned Portable Assigned Non-Portable Assigned Non-Portable Allocation & assignment terms • Terms used in ‘status’ field in the APNIC database • Describes “portability” of the address space

  8. Policies ISP Allocation ISP Customer Assignments Customer Assignments Aggregation and “portability” Aggregation No Aggregation BGP Announcement (1) BGP Announcements (4) (Non-portable Assignments) (Portable Assignments)

  9. Policies ISP A ISP A ISP B ISP B Internet Internet ISP C ISP C ISP D ISP D Aggregation and “portability” Aggregation No Aggregation (4 routes) (21 routes) (Non-portable Assignments) (Portable Assignments)

  10. Policies APNIC Policies - objectives • Conservation • Ensuring efficient use and conservation of resources • Aggregation • Limiting growth of routable prefixes • Registration • Registering the Internet resources in a public db • Uniqueness • Global visibility • Fairness and consistency • Equal consideration irrespective of external factors

  11. Policies Why do we need policies ?- Global IPv4 Delegations

  12. Policies But they cannot be relied on forever Projected routing table growth without CIDR CIDR made it work for a while ISPs tend to filter longer prefixes DeploymentPeriod of CIDR Growth of global routing table http://bgp.potaroo.net/as1221/bgp-active.html • last updated 29 Sep 2003

  13. Policies Routing table prefix distribution Last updated 29 Nov 2002

  14. Policies APNIC policy environment “IP addresses not freehold property” • Assignments & allocations on license basis • Addresses cannot be bought or sold • Internet resources are public resources • ‘Ownership’ is contrary to management goals “Confidentiality & security” • APNIC to observe and protect trust relationship • Non-disclosure agreement signed by staff

  15. Policies APNIC allocation policies • Aggregation of allocation • Provider responsible for aggregation • Customer assignments /sub-allocations must be non-portable • Allocations based on demonstrated need • Detailed documentation required • All address space held to be declared • Address space to be obtained from one source • routing considerations may apply • Stockpiling not permitted

  16. Policies Initial IPv4 allocation criteria 1a. Have used a /22 from upstream provider • Demonstrated efficient previous address usage OR 1b. Show immediate need for /22 • Can include customer projections & infrastructure equipment 2. Detailed plan for use of /21 within a year 3. Renumber to new space within 1 year • Meet all policy requirements • Applicants may be required to show purchase receipts

  17. Policies APNIC allocation policies • Transfer of address space • Not automatically recognised • Return unused address space to appropriate IR • Effects of mergers, acquisitions & take-overs • Will require contact with IR (APNIC) • contact details may change • new agreement may be required • May require re-examination of allocations • requirement depends on new network structure

  18. Policies Address assignment policies • Assignments based on requirements • Demonstrated through detailed documentation • Assignment should maximise utilisation • minimise wastage • Classless assignments • showing use of VLSM • Size of allocation • Sufficient for up to 12 months requirement

  19. Policies Small multihoming assignment policy 1a. Applicants currently multihomed OR 1b. Demonstrate a plan to multihome within 1month 2. Agree to renumber out of previously assigned space • Demonstrate need to use 25% of requested space immediately and 50% within 1 year • Meet all policy requirements or have the assignment revoked

  20. Policies IPv4 assignment policy for IXPs IXPs can apply for an assignment of /24 for Transit LAN Criteria • 3 or more peers • Demonstrate “open peering policy” • APNIC has a reserved block of space from which to make IXP assignments

  22. APNIC Policy Update

  23. 16th APNIC Open Policy Meeting • 19th – 22nd August, Seoul, Korea • Held in conjunction with Korea Internet Operations Workshop (KIOW) • Longest banners of any APNIC meeting

  25. Policy Update from APNIC16.. • Prop-005-v001: RIPE-261 follow up • Regional allocations • Larger allocation size from IANA • Size /8 or /12 needs further discussion • Prop-006-v001: Historical resource transfers • Allows transfers from ‘historical’ to ‘current’ status • Recipient must be an APNIC member • Address space subject to current policy framework • Prop-011-v001: Revised IXP assignment policy • Definition amended, restriction on routing lifted • Further discussion required for remainder of proposal
