In 2015, ARIN (responsible for the North American region) became the first<\/a><\/noindex> registrar to exhaust its IPv4 pool. And in November, addresses also ran out for RIPE, which allocates resources in Europe and Asia.<\/p>\n

The situation in RIPE<\/h2>\n

\nIn 2012, RIPE announced<\/a><\/noindex> announced the start of distribution of the last \/8 block. Since then, each registrar's client could receive only 1024 addresses, which slightly slowed the depletion of the pool. But by 2015, RIPE had 16 million free IPs, and by summer 2019, this number had decreased to 3 million<\/a><\/noindex>.<\/p>\n

At the end of November, RIPE published a letter<\/a><\/noindex>, in which they reported that the registrar had given out the last IPs and its resources were exhausted. From that moment on, the pool will only be replenished with addresses returned by various organizations. They will be distributed in order in blocks of \/24.<\/p>\n

Who still has addresses<\/h2>\n

\nIPv4 is still available from three registrars, but in recent years they have been operating in a 'strict economy mode.' For example, the African AFRINIC has imposed restrictions on the number of addresses issued and strict checks on their intended use. Despite all measures, experts predict that the IPv4 from the African registrar will run out<\/a><\/noindex> will be exhausted by March 2020. However, there is an opinion that this may happen even earlier\u2014in January.<\/p>\n

A few resources are still left with the Latin American LACNIC\u2014it is distributing the last \/8 block. Representatives of the organization say they give out a maximum of 1024 addresses per company. At the same time, only companies that have never received them before can purchase<\/a><\/noindex> blocks can only be received by those clients who have never received them before. Similar measures have been implemented in the Asian APNIC. However, the organization has only<\/a><\/noindex> one-fifth of the \/8 pool left, which will also run out soon.<\/p>\n

It's not over yet.<\/h2>\n

\nExperts note that the 'lifespan' of IPv4 can be extended. It is enough to return unused addresses to the general pool. For example, Ford Motor Company and Prudential Securities hold<\/a><\/noindex> more than 16 million public IPv4 addresses. In a themed thread on Hacker News it was suggested<\/a><\/noindex>, that these organizations do not need such a large number of IPs.<\/p>\n

Moreover, returned addresses should be issued not in blocks as before, but in strictly necessary quantities. Another resident of HN explained<\/a><\/noindex>, noted that providers Spectrum\/Charter and Verizon are already adopting this practice\u2014they are issuing one IP from \/24 instead of a whole block \/30.<\/p>\n
