Number Resource Allocation Data

Our primary role in managing Internet number resources is to provide pools of unallocated IP addresses and AS numbers to Regional Internet Registries (RIRs) according to their needs as described by ICANN's Global Addressing Policies.

These policies contain allocation algorithms that are based on the level of resource utilization of prior allocations. We track allocation rates here and provide analysis of eligibility for future RIR allocations.

IP Address Allocations

The chart below summarizes allocations of IPv6 addresses RIRs have made to network operators. IPv4 is not represented as IANA's supply has been exhausted and our allocation method for recovered address space does not factor in utilization.

Detailed information is available for each RIR by clicking the chart.

Autonomous System Number Allocations

The chart below summarizes allocations of AS numbers that RIRs have made to network operators. Detailed information is available for each RIR by clicking the chart.
