ARIN IPv6 Allocations

Allocations of IPv6 address space are made to regional Internet registries according to their needs, based on allocation rates they publish. Specifically, RIRs are eligible for further allocations if their available space of existing allocations is less than 50% of a /12 address block, or less than their necessary space for the following 9 months.
