Global Cooperation

IP addressing

Many different organizations contribute to the coordination and management of the Internet. Some concentrate on technical standards, others on website addresses, APNIC's area of focus is on numeric Internet resources - IP addressing and Autonomous System numbers.

What is an IP address?

Network Operator Groups (NOGs) are an important source of community offering industry support, training opportunities and peer information sharing.

Number Resource Organization (NRO)

The NRO coordinates the joint activities of the RIRs, including technical projects, liaison activities, and policy coordination.

Address Supporting Organization (ASO)

The ASO and NRO are in essence the same organization. The ASO Address Council and NRO Number Council are synonymous and interchangeable, and they are chaired by the same people.

In RIR parlance, 'ASO' is deprecated over 'NRO', and consensus mandates that all references to the 'ASO' be changed to 'NRO'. Essentially, the ASO, while still defined on paper, does not exist beyond its definition in the ICANN Bylaws.

NRO Number Council

Three individuals are appointed to the Number Council (NC) from each of the Regional Internet Registry region. The RIR's are free to select these members in any way they see fit.

In the APNIC region, two members are directly elected by the Internet community. APNIC holds an election each year (normally in August or September) to re-elect one representative. Each representative serves a two year term.

The third member is appointed by the APNIC EC for a one-year term. This appointment is made each year, in the later part of the year. All terms start on 1 January following the election or appointment.

The primary goals of the RIR system are:

  • Conservation: to ensure efficient use of a finite resource and to avoid service instabilities due to market distortions (such as stockpiling or other forms of manipulation)
  • Aggregation (routability): to assist in maintenance of Internet routing tables at a manageable size, by supporting CIDR techniques to ensure continued operational stability of the Internet
  • Registration: to provide a public registry documenting address space allocations and assignments, necessary to ensure uniqueness and provide information for Internet troubleshooting at all levels.
