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.

24 Month Forecast
The chart below uses ARIN's current average allocation rate to forecast their available IPv6 space over the next 24 months. This can be used to estimate if ARIN will become eligible to apply for additional IPv6 space in the near future.
