An Update on IPv4 Depletion

In a post back in May, I discussed the fact that there were 55 remaining /8 IPv4 blocks remaining in the IANA unallocated address pool at the beginning of this year. 7 additional blocks had been allocated in 2007 as I wrote the post, and I predicted that by the end of the year 12 – 15 /8s would be allocated.

So where do we stand so far?

With Q4 of 2007 remaining to go, 11 /8s have been allocated. Here are the blocks, the RIRs to whom they were allocated, and the date:

- 116/8                        APNIC            January 07                        APNIC            January 07                        APNIC            January 07                        APNIC            January 07                        APNIC            January 07                          RIPE               March 07                          RIPE               March 07                          RIPE               July 07                          RIPE               July 07                        LACNIC         September 07                        LACNIC         September 07

- 117/8

- 118/8

- 119/8

- 120/8

- 92/8

- 93/8

- 94/8

- 95/8

- 186/8

- 187/8

AfriNIC has only one /8, allocated in 2006, but it’s an even bet whether they will ask for any more this year; I’m guessing they won’t. ARIN, however, has not yet taken an allocation this year. They took 3 in 2004, 4 in 2005, and another 4 in 2006. Given that trend, they’ll probably ask for 4 or 5 /8s before the end of this year.

Related to all this, Tony Hain has a cool fractal map depicting IPv4 allocations starting in January of 2000, going through the present, and ending in January of 2010. Have a look.
