  14. Policy Development in the Asia Pacific The APNIC Community & the Policy Development Process

  15. What is the APNIC community? • Open forum in the Asia Pacific • Open to any interested parties • Voluntary participation • Decisions made by consensus • Public meetings • Mailing lists • web archived • A voice in regional Internet operations through participation in APNIC activities

  16. Participation in policy development • Why should I bother? • Responsibility as an APNIC member • To be aware of the current policies for managing address space allocated to you • Business reasons • Policies affect your business operating environment and are constantly changing • Ensure your ‘needs’ are met • Educational • Learn and share experiences • Stay abreast with ‘best practices’ in the Internet

  17. Policy development cycle OPEN Need Anyone can participate Evaluate Discuss ‘BOTTOM UP’ TRANSPARENT Consensus Implement Internet community proposes and approves policy All decisions & policies documented & freely available to anyone

  18. How to make your voice heard • Contribute on the public mailing lists • http://www.apnic.net/community/lists/index.html • Attend meetings • Or send a representative • Gather input at forums • Give feedback • Training or seminar events

  19. Come to the APNIC meeting! • APNIC 18 • Nadi, Fiji, 31 Aug- 3 Sep 2004 • Participate in policy development • Attend workshops, tutorials & presentations • Exchange knowledge and information with peers • Stay abreast with developments in the Internet • View multicast online • Provide your input in matters important to you • Fellowships Available • http://www.apnic.net/meetings/18

  21. Internet Registry Allocation and Assignment Policies

  22. Policies Overview of APNIC policies • Definitions • Objectives • Environment • Allocation & Assignment Policies • Summary

  23. 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’)

  24. 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

  25. 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  

  26. Address management objectives • Aggregation • Limit routing table growth • Support provider-based routing • Conservation • Efficient use of resources • Based on demonstrated need • Registration • Ensure uniqueness • Facilitate trouble shooting

  27. Policies Why do we need policies ?- Global IPv4 Delegations (Pre-RIR)

  28. 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 09 Mar 2004

  29. Policies Routing table prefix distribution Last updated Feb 2004

  30. 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

  31. 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

  32. Policies /8 APNIC Non-portable assignment Portable assignment Policy will change Based on the APNIC 17 consensus Initial IPv4 allocation • Initial (portable) allocation: /20 (4096 addresses). • The allocation can be used for further assignments to customers or your own infrastructure. Criteria 1a. Have used a /22 from upstream provider • Demonstrated efficient address usage OR 1b. Show immediate need for /22 • Can include customer projections & infrastructure equipment 2. Detailed plan for use of /21 within 1 year 3. Renumber to new space within 1 year /20 Member allocation

  33. IPReq Initial IPv4 allocation criteria • Min allocation size may be lowered from /20 to /21 • LIR have used a /23 from their upstream provider or demonstrate an immediate need for a /23; and 2. Detailed plan for use of a /22 within a year 3. Renumber to new space within 1 year • Meet all policy requirements • Applicants may be required to show purchase receipts APNIC 17 Consensus

  34. Policies /8 APNIC /20 Member allocation Non-portable assignment Portable assignments • Small multihoming assignment policy • For (small) organisations who require a portable assignment for multi-homing purposes Criteria 1a. Applicants currently multihomed OR 1b. Demonstrate a plan to multihome within 1 month 2. Agree to renumber out of previously assigned space • Demonstrate need to use 25% of requested space immediately and 50% within 1 year Portable assignment

  35. Portable assignments for IXPs Criteria • 3 or more peers • Demonstrate “open peering policy” • APNIC has a reserved block of space from which to make IXP assignments

  36. Portable critical infrastructure assignments • What is Critical Internet Infrastructure? • Domain registry infrastructure • Root DNS operators, gTLD & ccTLD operators • Address Registry Infrastructure • RIRs & NIRs, IANA • Why a specific policy ? • Protect stability of core Internet function • Assignment sizes: • IPv4: /24 • IPv6: /32

  37. Renumbering & return policy • Renumbering? • one-for-one exchange to assist renumbering • needs confirmation from upstream ISP to confirm renumbering will take place • ‘No Questions Asked’ return prefix policy • swap 3 or more discontiguous prefixes (ISP or customers) for single prefix, no charge • ftp://ftp.apnic.net/apnic/docs/no-questions-policy • Form for returning addresses • ftp://ftp.apnic.net/apnic/docs/address-return-request

  39. Internet Registry Procedures Addressing Plan

  40. AddressingPlan Addressing plan • To complete documentation • First need a technical PLAN • Documenting the architecture of the present and eventual goal • IP addressing is fundamental part of network design • IP addressing ‘planning’ example to follow..

  41. AddressingPlan Some icons Router (layer 3, IP datagram forwarding) Network Access Server (layer 3, IP datagram forwarding ) Ethernet switch (layer 2, packet forwarding)

  42. AddressingPlan Addressing plan • Identify components of network • Customer services • ISP internal infrastructure • Identify phases of deployment • Starting off, 6 months, 12 months • Identify equipment and topology changes • Need for redundancy • Need for increased scale
