The European Network Coordination Centre (RIPE NCC), which is responsible for Internet resource allocation in the United Kingdom, Europe, the Middle East and parts of Central Asia, recently announced that all 4.3 billion IPv4 addresses worldwide have been allocated. This means that no more IP4 addresses can be allocated to ISPs (network service providers) and other large network infrastructure providers.
In fact, people have been prepared for global IPv4 addresses. Today, this moment has finally arrived. All 4.3 billion IP4 addresses in the world have been allocated, which means that no more IP4 addresses can be allocated.
RIPE NCC confirmed in an email that at 15:35 UTC + 1 time on November 25, 2019, RIPE NCC made the final allocation from the last remaining address in the available pool. Today, global IPv4 addresses are exhausted.
In fact, IPv4 top-level addresses were exhausted in 2012. At that time, all IP4 address space had been allocated to the world’s five largest regional Internet registries. Soon, the five regional Internet registries exhausted their IPv4 addresses.
On April 15, 2011, the Asia-Pacific Internet Registry allocated the last IPv4 block; on June 10, 2014, Latin America and the Caribbean allocated the last IPv4 block; a year later, on September 24, 2015, the North American region allocated the last IPv4 block. Today, all European regions are also allocated.
Although IPv4 addresses are exhausted, countries around the world have already begun to deploy IPv6. China Academy of Information and Communications Technology (ICT) released data in September this year. The latter said that as of May this year, China had 311 million active IPv6 users.
