RIPE NCC now allocating IPv4 address space from the last /8 netblock

Earlier today, the RIPE NCC (Réseaux IP Européens Network Coordination
Centre) announced it is down to its last "/8" worth of IPv4 addresses.
This means that it is no longer possible to obtain new IPv4 addresses in
Europe, the former USSR, or the Middle East, with one small exception:
every network operator that is a "RIPE member" or "local Internet
registry" (LIR) can obtain one final block of 1024 IPv4 addresses. To
fulfill these requests, the RIPE NCC is keeping that last /8, which
contains 16.8 million addresses, in reserve.  RIPE NCC

None of this comes as a surprise given that the global pool of free IPv4
addresses was emptied in February 2011. APNIC, which distributes IP
addresses in the Asia-Pacific region, ran out of IPv4 addresses in May
2011; it has been working under the "final /8" regime ever since. The
remaining three Regional Internet Registries are AfriNIC (Africa),
LACNIC (Latin America and the Caribbean), and ARIN (North America),
which all have enough IPv4 addresses to last at least two more years.

Since the depletion of IPv4 address space in the APNIC region, little
information has surfaced about how network operators in the region have
managed the situation. However, the lack of IPv4 addresses only impacts
organizations and consumers who need additional addresses, or who need
addresses for the first time. Existing IPv4 users remain unaffected, and
so the immediate impact is limited. Also, large network operators get
large address blocks from the RIRs and they typically have a pool of
unused addresses of their own, so few will be experiencing immediate
problems.

However, every year for the past five years, some 200 million new IPv4
addresses have been put into use. Without a steady supply of fresh
addresses, many Internet-related activities are going to become
problematic in the years to come. Fortunately, 20 years ago the Internet
Engineering Task Force (IETF) foresaw that the 3.7 billion addresses
afforded by the 32-bit IPv4 address space would become a problem, and
started working on a replacement: IPv6. But the IPv4 depletion didn't
happen as fast as the IETF originally predicted, and IPv6 adoption has
languished. But recently, IPv6 adoption got a big push in the form of
World IPv6 Launch. Eventually, IPv6 will replace IPv4, but the
transition won't be pretty.
