IPv4 all gone

The news has been announced.  In the last two hours, APNIC have been allocated the last two /8s in the IPv4 address pool, which will trigger the distribution of the ‘final five’ blocks, one to each Regional Internet Registry, which officially means that there are no more IPv4 addresses left in the IANA pool.

What does this mean now?  Well, each RIR still has a stock of addresses.  With APNIC taking the last two blocks, they now have in the region of 3.2 /8s left, ARIN have about the same, and RIPE have nearly 4.  Obviously each RIR will get an additional 1/8 from the ‘final five’ in addition to this.  Current estimates are that these addresses will be gone in around 6 months.

Party time!
