No, not exactly. It was a little dirty clickbait. However, at the RIPE NCC Days conference, held on September 24-25 in Kyiv, it was announced that the distribution of \/22 subnets to new LIRs will soon come to an end. The issue of IPv4 address space exhaustion has been discussed for a long time. It has been about 7 years since the last \/8 blocks were allocated to regional registries. Despite all the restraining and limiting measures, the inevitable could not be avoided. What awaits us as a result is below.<\/p>\n

Historical Overview<\/h3>\n

\nWhen all your internets were just being created, people thought that 32 bits for addressing would be more than enough. 232 is approximately 4.2 billion addresses for network devices. Could the first few organizations that united into a network in the distant 80s have thought that someone would need more? Back then, the first address registry was maintained by a guy named Jon Postel manually, almost in a regular notebook. A new block could be requested over the phone. Periodically, the current allocated addressing was published as an RFC document. For example, in RFC790<\/a><\/noindex>, published in September 1981, we first encounter the familiar 32-bit representation of IP addresses.<\/p>\n

But the concept had 'caught on', and the global network began to develop actively. This led to the emergence of the first electronic registries, but it was not yet a pressing issue. With justification, one could quite easily get a \/8 block (over 16 million addresses) in one's hands. It's not that the justifications were thoroughly checked back then.<\/p>\n

We all understand that if you actively consume a resource, sooner or later it will run out (may the mammoths rest in peace). In 2011, IANA, which allocated address blocks on a global scale, handed out the last \/8 blocks to regional registries. On September 15, 2012, RIPE NCC announced the exhaustion of IPv4 and began distributing no more than \/22 (1024 addresses) to one LIR (however, it allowed opening several LIRs for one company). On April 17, 2018, the last block 185\/8 ran out, and for the past year and a half, new LIRs have been feeding on breadcrumbs and forage \u2013 blocks returned to the pool for various reasons. Now they are running out too. You can observe this process in real-time at https:\/\/www.ripe.net\/manage-ips-and-asns\/ipv4\/ipv4-available-pool<\/a><\/noindex>.<\/p>\n

The train has left.<\/h3>\n
