2. General Definitions
The following terms and their definitions are of particular importance to the understanding of the goals, environment, and policies described in this document.
2.1 Internet Registry (IR)
An Internet Registry (IR) is an organization that is responsible for distributing IP address space to its customers and for registering those addresses. IRs are classified according to their primary function and territorial scope within the hierarchical structure.
2.2 Regional Internet Registry (RIR)
Earlier, Regional Internet Registries (RIRs) were established under the authority and initiatives of the internet communities in their respective regions. Currently, the ICANN authorises establishment of RIRs to serve and represent large geographical regions.The primary role of RIRs is to manage and distribute public Internet address space within their respective regions.
2.3 Local Internet Registry (LIR)
A Local Internet Registry (LIR) is an IR that receives allocations from an RIR and primarily assigns address space to 'end-users'. LIRs are generally ISPs. Their customers are other ISPs and possibly end-users. LIRs must be members of AFRINIC.
To "allocate" means to distribute address space to LIRs for the purpose of subsequent distribution.
To "sub-allocate" means to distribute address space (by LIRs) to ISPs for the purpose of subsequent distribution.
An assignment is an IP block given by an LIR to the end-users for their own usage. To "assign" means to delegate address space to an ISP or End User for specific use within the Internet infrastructure they operate. Assignments must only be made for specific purposes documented by specific organisations and are not to be sub-assigned to other parties.
2.7 PA (Provider Aggregatable) IP space
PA space is what has been allocated to LIRs from which they can assign or sub-allocate to end-users / downstream networks as non-portable block. If the end-user / downstream network changes provider, the address space assigned or sub-allocated by the previous service provider (LIR) should be returned and the network renumbered.
2.8 PI (Provider Independent) IP space
PI (or portable) space cannot be aggregated and can only be assigned by RIR through an LIR. PI space is expensive to route and might not be globally routable. Sub-allocations cannot be made from this type of address space by the end user or LIR.
