Dear colleagues, Yesterday, on 1 March 2016, the RIPE NCC and other Regional Internet Registries (RIRs) were each allocated the equivalent of a /15 of IPv4 address space from the Internet Assigned Numbers Authority (IANA). The RIPE NCC received the IPv4 address ranges 45.65.64.0/18, 147.78.0.0/16, 192.144.0.0/18 and 192.145.0.0/17. We are currently adding these to our available pool. Following the exhaustion of IANA's free pool of IPv4 addresses in 2011, when the RIRs received their final /8s, a global policy caused IANA to create a recovered pool of leftover and returned IPv4 address blocks. This policy was ratified by all five RIR communities in 2012 and stated that IANA would begin making equal, periodic allocations from the recovered pool when the first RIR reached a /9 of remaining addresses. This point was reached by LACNIC, the RIR for Latin America and the Caribbean on 20 May 2014, triggering the global policy and the first post-exhaustion allocation from IANA. You can read the global policy here: https://www.icann.org/resources/pages/allocation-ipv4-post-exhaustion-2012-0... With the current policy in place, the RIPE NCC will receive one-fifth of any recovered addresses in the pool every six months (every March and September). The RIPE NCC will continue to distribute these according to the current last /8 policy, under which Local Internet Registries (LIRs) may receive a one-time /22 allocation (1,024 addresses). It is important that network operators continue to deploy IPv6 on their networks to ensure the future growth of the Internet.
