According to foreign media reports, the European Network Coordination Center (RIPE NCC), which is responsible for the allocation of Internet resources in the UK, Europe, the Middle East and parts of Central Asia, announced today:
All 4.3 billion IPv4 addresses in the world have been allocated, which means there are no more IPv4 addresses to be allocated to ISPs (Internet Service Providers) and other large network infrastructure providers.

The translation is as follows:
Dear Colleagues,
Today, at 15:35 UTC+1, 25 November 2019, we made our final /22 IPv4 allocation from the last remaining addresses in the available pool. We have now run out of IPv4 addresses.
For network operators, our announcement should not come as a surprise - the RIPE community has long anticipated and planned for IPv4 exhaustion. In fact, it is thanks to the community's responsible stewardship of these resources that we have been able to deliver /22 allocations to thousands of new networks in our service area since reaching our last /8 in 2012.
As you can see from the email, we were not surprised by this incident
but were prepared for it.
IPv4 has been used for more than 30 years. In the early days, the Internet was designed only for the US military, and it was not considered that it would become so large and become a global network.
After entering the 21st century, with the rapid popularization of computers and smart phones, the Internet began to develop explosively, more and more Internet-connected devices appeared, and more and more people began to connect to the Internet. This means that more and more IP addresses are needed.
The problem of insufficient addresses actually started as early as 1990 when IETF (Internet Engineering Task Force, founded in late 1985 and the most authoritative technical standardization organization for the global Internet) began planning the next generation protocol of IPv4.
That’s right, it’s IPv6
that claims to be able to “
assign an IP to every grain of sand on the earth
.”
In addition, according to the predictions of experts at the beginning of this century, our IPv4 addresses have been exhausted tens of thousands of times
. The reason why we have been able to "survive" until now is mainly that
in addition to IPv6, we have some other technologies that can alleviate the shortage of addresses in disguise
,
such as
NAT
(Network Address Translation).
Last month, at the 6th World Internet Conference held in Wuzhen, China Telecom stated: "China Telecom's metropolitan area network, mobile network, backbone network, IDC, etc. have all achieved commercial deployment of IPv6. Currently, it has built the largest and most comprehensive IPv6 network" and "has allocated IPv6 addresses to more than 300 million users."
