Rir model structure
RIR Model - Structure

  • Bottom-up, industry, self-regulatory structure

    • Open and transparent

    • Neutral and impartial

  • Not for profit organizations

    • Membership open to all interested parties

    • Membership elects Board of Trustees and Advisory Council

    • Membership approves activities & budget

  • RIRs do NOT register domain names

  • Formation of icann
    Formation of ICANN

    • US Government decision to end USG management of the global Internet

    • Internet Corporation for Assigned Names and Numbers (ICANN) formed as the industry self-regulatory body



    Icann aso

    • Formed by RIRs based on existing and proven regional policy structures

    • Responsible for global policy coordination within ICANN framework

    • Advisory Council elected by RIR communities

    Role of the ac
    Role of the AC

    • to be a catalyst in the policy process,

      • not to develop policy,

      • but to oversee and coordinate the policy development process facilitated by the RIRs

    • Make recommendations to the ICANN board on addressing issues

    • Elect three members of the ICANN Board of Directors

    Rir activities

    • Address space management

    • Registration

    • Policy development

    Address management challenges
    Address ManagementChallenges

    • Address space depletion

      • IPv4 address space is finite

      • Historically, many wasteful allocations

    • Routing chaos

      • Legacy routing structure, router overload

      • CIDR & aggregation are now vital

    • Inequitable management

      • Unstructured and wasteful address space distribution

    Address management objectives

      • with consensus of community

      • Participation open to everyone

    • Responsive policy development

      • fair to all

      • changing requirements of industry

      • new technology (G3 phones, GPRS, cable)

      • evolution of process

    • Technical challenges

      • high level of planning and expertise required

      • meeting demands of a changing environment
