IPv4 Exhaustion

On 14 September 2012, the RIPE NCC began to allocate IPv4 address space from the last /8 of IPv4 address space it holds.

What does this mean?

The RIPE NCC now allocates the IPv4 address space it holds according to section 5.1 of "IPv4 Address Allocation and Assignment Policies for the RIPE NCC Service Region", which states that RIPE NCC members can request a one time /22 allocation (1,024 IPv4 addresses). No new IPv4 Provider Independent (PI) space will be assigned.
