We received the following IPv4 address ranges: 192.54.244.0/24 192.144.75.0/24 192.188.248.0/24 205.211.83.0/24 This returned address space will be added to our free pool and distributed according to the current IPv4 policy. LIRs that have already received their final /22 are NOT eligible to receive any further allocations from the RIPE NCC. You can find the IPv4 policy here: <a class="moz-txt-link-freetext" href="https://www.ripe.net/publications/docs/ripe-708">https://www.ripe.net/publications/docs/ripe-708</a> 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: <a class="moz-txt-link-freetext" href="https://www.icann.org/resources/pages/allocation-ipv4-post-exhaustion-2012-05-08-en">https://www.icann.org/resources/pages/allocation-ipv4-post-exhaustion-2012-05-08-en</a> It is important that network operators continue to deploy IPv6 on their networks to ensure the future growth of the Internet.
