when did iana make the final /8 allocations of ipv4 addresses
IPv4 address exhaustion On 31 January 2011, the last two unreserved IANA /8 address blocks were allocated to APNIC according to RIR request procedures. This left five reserved but unallocated /8 blocks.[9][18][19] In accord with ICANN policies, IANA proceeded to allocate one of those five /8s to each RIR, exhausting the IANA pool,[20] at a ceremony and press conference on 3 February 2011.
