On the afternoon of November 26, Beijing time, according to foreign media reports, the European Network Coordination Center (RIPE NCC), which is responsible for the allocation of Internet resources in the United Kingdom, Europe, the Middle East and parts of Central Asia, recently announced that all 4.3 billion IPv4 addresses in the world have been allocated. Finished, this means that no more IPv4 addresses can be allocated to ISPs (Internet Service Providers) and other large network infrastructure providers.
Note that the above sentence means that the allocation is complete, that is to say, the allocation is complete. The real situation is that it has not been used up yet. If you go to Alibaba Cloud, Tencent Cloud, Huawei Cloud and other cloud giants to buy cloud services, the allocation is still IPv4.
Some media deliberately guide everyone in the title and content, saying that the IPv4 address is used up, which is a big mistake, and is deceiving the majority of programmers.
All 4.3 billion IPv4 addresses in the world have been allocated, which means that there are no more IPv4 addresses to be allocated. But you don't need to worry too much, because IPv6 has already been used in our country. As of May this year, the number of active IPv6 users in China reached 311 million. Among them, in terms of video applications, iQiyi has 178 million active users, Youku has 120 million active users, and Tencent Video has 60 million active users.
In fact, the exhaustion of IPv4 does not mean that it will be used up, because there will be some ips that will be reserved!
Later, I believe many netizens will write many articles to teach you how to use IPv6.
After IPv4 is allocated, it will only accelerate the arrival of IPv6!
In June 2018, the three major operators and Alibaba Cloud announced that they will fully provide IPv6 services to the outside world, and plan to help China's Internet truly realize "IPv6 Only" by 2025.
In April 2019, the Ministry of Industry and Information Technology also issued a notice on launching a special action for IPv6 network readiness in 2019.
It can be said that we have been prepared, and whether it is Xiaomi or Huawei, their terminal equipment has already supported IPv6. In fact, one-third of our netizens have already used IPv6.
