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, https://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:
