ARIN enters IPv4 exhaustion phase two

This week we saw another step towards IPv4 address exhaustion.  The American Registry for Internet Numbers (ARIN) reached 3.00 /8s of space remaining, this triggers phase two of its exhaustion planning.  This sees requests move to a first in first out model and overall criteria for allocations tightening.  Not exhaustion, but considering just how quickly addresses dissappeared this week (from 3.02 /8s to 2.89 /8s over night) we will be there soon enough.  For more details on what this really means:

RIPE IPv4 pool exhausted

September 14th 2012 was another big day for IPv6.  Today the RIPE Regional Address Registry (RAR) exhausted its IPv4 pool:

This triggers section 5.6 of its IPv4 Address Allocation and Assignment Policies.  While these procedures do allow RIPE members to allocate IPv4 addresses still but only in very tiny allocations and only if they already have an IPv6 allocation.  In particular they are limited to a single allocation:

1a. LIRs may only receive one allocation from this /8.  The size of the allocation made under this policy will be exactly one /22.

With two of the five RARs now essentially out of IPv4 addresses this has to help spur on the adoption of IPv6.  One can hope.
