ARIN’s IPv4 free pool continues it slow march to depletion. Recently, the pool passed the symbolic level of a /9. Today in mid-December 2014, Geoff Huston’s projection shows the depletion date of April 14, 2015, but a few large allocations could certainly cause the pool to be depleted much sooner.
ARIN also has an additional /10 which will be used for IPv6 transition technologies under a separate assignment policy (NRPM 4.10).
