In slightly unexpected news, ARIN reached their final /8 today supposedly because of the allocation of a /10 to Akamai, which reduced the space free from just over 1.25 /8s to 1 /8s exactly.  This means that ARIN are now in ‘Phase 4’, where all address allocation requests are closely scrutinised, and requests for /15 are above are closely scrutinised by a senior member of ARIN.

I haven’t seen the actual allocation figures yet, but this really should be the starting gun for Americans everywhere to start thinking about taking their heads out of the sand and rolling out IPv6.  It’s now going to be a lot harder to get allocations out of ARIN, and it can’t be long before total exhaustion is upon us.  Geoff Huston’s meter is probably going to be wound forward by months in the morning.
