The internet, a vast network of networks, requires a structured approach to manage its massive system. This is where Internet Number Resources come into play, with organizations like Regional Internet Registries (RIRs) playing a crucial role.

The Role of RIRs
RIRs manage the distribution and registration of Internet resources such as IP addresses and Autonomous System (AS) numbers within designated global regions. They cater to a diverse customer base, including ISPs, governments, educational institutions, and end-users.
Membership policies vary across RIRs, but they universally aim to meet the needs of any party requiring internet resources. Distribution of resources by RIRs adheres to established guidelines, ensuring fair and impartial allocation. Each IP address or ASN is strictly assigned to a single entity, a critical task for RIRs that preserves resource functionality and avoids chaos in distribution.
The system of RIRs operates across different geographic regions. This decentralization guarantees a balanced worldwide distribution of resources, helping maintain global network functionality and deterring any region from monopolizing these vital resources.
The Five RIRs
There are five RIRs, each responsible for a specific region of the world:
- African Network Coordination Centre (AFRINIC): Founded in 2005 in Mauritius, AFRINIC has 2,000+ members from Africa, including resource and associate members.
- Asia-Pacific Network Coordination Centre (APNIC): Established in 1993 in Australia, APNIC serves the Asia Pacific region with 22,000+ members, including tiered members, non-members with resources, and associate members.
- American Registry for Internet Numbers (ARIN): Based in the USA and founded in 1997, ARIN serves the US, Canada, and parts of the Caribbean with 16,000+ members, including service members, legacy customers, and ASN-only organizations.
- Latin American and Caribbean Internet Addresses Registry (LACNIC): Founded in 2002 in Uruguay, LACNIC serves Latin America and the Caribbean with 12,000+ members, including Active and Adhering Members.
- Réseaux IP Européens Network Coordination Centre (RIPE NCC): Established in 1992 in the Netherlands, RIPE NCC serves Europe, the Middle East, and parts of Central Asia with 23,000+ members, including local internet registries and end users.
The Relationship with IANA
The Internet Assigned Numbers Authority (IANA) is responsible for the global coordination of the DNS Root, IP addressing, and other Internet protocol resources. IANA allocates large blocks of IP addresses and ASNs to the RIRs, who then distribute them to their customers in their respective regions. This system ensures a structured and coordinated approach to IP address allocation worldwide.
National Internet Registries (NIRs)
In some regions, a National Internet Registry (NIR) is established to manage the distribution of IP addresses at a national level. NIRs operate under the umbrella of an RIR and follow the same policies and procedures.
The Number Resource Organization (NRO)
The Number Resource Organization (NRO) is a coordinating body for the five RIRs. It was established in 2003 to promote and protect the unallocated number resource pool, promote and coordinate RIRs’ activities, and serve as a focal point for Internet community input into the RIR system.
Conclusion
In conclusion, RIRs play a critical role in the management of Internet number resources. They ensure the fair distribution and efficient use of IP addresses and ASNs, and contribute to the stability and reliability of the Internet.
