rir basis
RIR Basis
  • Proposed by IETF in early 1990’s
    • RFC 1174 (1990)
      • “IAB Recommended Policy on Distributing Internet Identifier Assignment…”
    • RFC1366 (1992)
      • “Guidelines for Management of IP Address Space”
      • Released with RFC1367 (CIDR)
  • Documents provided rationale for RIRs
    • Criteria for establishment
    • Operating guidelines
  • American Registry for Internet Numbers
    • Founded in 1993, as division of “InterNIC”
    • Independent association since 1997
    • 1,317 members
  • Service Region: North & South America, the Caribbean, Africa south of equator
    • 70 countries

other rirs

Service Region: Asia, Oceania and Western Pacific

Located in Brisbane, Australia


Service Region: Europe, Middle East, Central Asia, Africa north of equator

Located in Amsterdam, the Netherlands

Emerging RIRs


Proposed Region: Latin America


Proposed Region: Continental Africa

Other RIRs
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
RIR Activities
  • Address space management
  • Registration
  • Policy development
  • Outreach
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
Address ManagementObjectives
  • Conservation
    • efficient use of resources
    • allocation based on demonstrated need
  • Aggregation
    • Limiting growth of routing table
    • provider-based addressing policies
  • Registration
    • Ensuring uniqueness
    • Troubleshooting
  • Fairness and Consistency
    • In the interests of regional and global communities
  • IPv4 and IPv6 Numbers Registration
  • AS Number Registration
  • Registration Call Center
  • Reverse Delegation
  • WHOIS Directory Service
  • Routing Registry Service
ipv4 allocation rate in 2000
IPv4 Allocation Rate in 2000

(1.28 /8)

(2.0 /8)

ipv4 unallocated
IPv4 Unallocated

Currently 38% of all IPv4 address space has not been allocated

(Reserved by the IANA)

ipv6 allocations
IPv6 Allocations
  • Allocations since 1999
  • A total of 75 IPv6 address blocks (/35s) allocated collectively
    • APNIC: 26
    • ARIN: 15
    • RIPE NCC: 34
  • Training and Education
    • Registration help desk
    • Standardized registration training programs
    • Attendance at local (state) ISP association meetings
  • Information dissemination
    • News agencies
    • Industry specific meetings (like the GSMNA)
    • Government Advisory Committee to the ICANN
policy development
Policy Development
  • Developed in open policy forums
    • within industry self-regulatory framework
    • 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
