At a ceremony held on 3 February, 2011 the Internet Assigned Numbers Authority (IANA) allocated the remaining last five /8s of IPv4 address space to the Regional Internet Registries (RIRs) in accordance with the Global Policy for the Allocation of the Remaining IPv4 Address Space. With this action, the free pool of available IPv4 addresses is now fully depleted. To read the full text of this announcement please go to:
To keep the community informed of the status of the ARIN's IPv4 address pool, we are now publishing a daily report of our IPv4 inventory of available addresses on our home page, www.arin.net.
ARIN still has a pool of IPv4 address space, and we will continue to make allocations in accordance with the policies documented in the Number Resource Policy Manual. The depletion of the IANA IPv4 free pool does have a direct impact on a number of policies. To review these specific impacts and learn more about how IANA IPv4 free pool depletion will effect ARIN Customers, please see:
