Request an IPv4 /22 From the Last /8
On Friday 14 September, 2012, the RIPE NCC, the Regional Internet Registry (RIR) for Europe, the Middle East and parts of Central Asia, distributed the last blocks of IPv4 address space from the available pool.
This means that an LIR can only receive a one-time /22 allocation (1,024 IPv4 addresses) if it can justify the need and already has an IPv6 allocation (see section 5.6 of “IPv4 Address Allocation and Assignment Policies for the RIPE NCC Service Region”).
LIRs can assign IPv4 address space to End Users and to their own network infrastructure. No new IPv4 Provider Independent (PI) space will be assigned.
You cannot receive IPv4 address space from the RIPE NCC unless you are an LIR.
