Is the first aid kit IPv4 really used up?
Is IPv4 really used up? In fact, Xiaolan is not surprised. After all, there are so many people in the world. The power of n is used up
4.3 billion IPv4 addresses have been allocated, which means that no more IPv4 addresses can be allocated to ISPs and other large-scale network infrastructure providers. In this way, I’m afraid that some cloud factories will start a new layout. After all, every time the air outlet comes, a group of experimenters will be stranded on the beach first.
The first aid kit is coming. What are we waiting for?
In fact, it’s not a good thing that the resources of IPv4 are exhausted. The first is that new IPv6 can be generated. The other is that new production sources can be promoted. At present, IOT, the Internet of vehicles, smart cities, consumer electronics and other emerging industries based on Internet communication are in rapid development, and the demand for network addresses is showing explosive growth. In the future, network addresses will become An important resource. In fact, the development prospect of the industry is still very broad. Compared with IPv4, IPv6 not only has a lot of assignable quantity, but also takes into account security and transmission efficiency.
In fact, our country has already begun to deploy the source and root server of IPv6 a long time ago. In order to ensure the Internet Security and lay out the development of IPv6 in advance, China has led and cooperated with the Internet wide organization to carry out the “snowman plan” and completed the installation of 25 IPv6 root servers in 16 countries around the world. Four of them have been deployed in China, breaking the previous lack of roots in China Server dilemma.
Because, for the network world, it is more dangerous for the root server not to control itself, and the most extreme situation is to directly erase the entire region from the Internet.
First aid kit “IPv6 only” program, root server
As early as June 2018, the three major operators, together with Alibaba cloud, have announced that they will provide IPv6 services to the outside world in an all-round way, and plan to boost the realization of “IPv6 only” in China’s Internet by 2025. You can log in to view the cloud server, and now there are more IPv4 / v6 dual port public test functions.
There are still many Xiaobai who don’t know where the source of our computer’s IPv4 network is. Today, there are only 13 IPv4 root servers in the world. One is the primary root server in the United States, and the other 12 are secondary root servers, including 9 in the United States, 2 in Europe, in the United Kingdom and Sweden, and 1 in Asia, both in the United States or its allies.
In fact, this message was released by Nikolas pediaditis at UTC + 1 15:35 on November 25, 2019. The last remaining addresses in the available pool were finally allocated to / 22 IPv4. Now, we’ve run out of IPv4 addresses.
For network operators, the announcement was not surprising – the rip community had long anticipated and planned to run out of IPv4.
In fact, it is because of the responsible management of these resources by the community that we are able to provide / 22 distribution to thousands of new networks in our service area after reaching the last / 8 in 2012.
Theoretically speaking, IPv4 address exhaustion should mean that no new IPv4 devices can be added to the Internet, but in fact, many factors will be alleviated.
What are the factors that influence it?
There are two reasons. First, ISPs can reuse and recycle unused IPv4 addresses. Second, because of NAT (network address translation), the same IP address can be used privately behind ISP routers. Of course, the last is the transition to IPv6. Now we should establish a good order, so that we can directly connect with peers through the Internet with a huge address space of 3.4 × 10 ^ 38.
If I say the process has been foreseen since the 1980s, do you believe it?
In fact, the top addresses were exhausted in 2012, when all IPv4 address space was allocated to five regional Internet registries, afrinic for Africa, arin for Antarctica, Canada, parts of the Caribbean and the United States, and APNIC for East Asia, Oceania South and South East Asia, lacnic for most of the Caribbean and Latin America as a whole, and rip NCC for Europe, Central Asia, Russia and West Asia.
As a result, regional Internet signups quickly start to run out.
On April 15, 2011, Asia Pacific (APNIC) allocated the last IPv4 block for Europe, the Middle East and Central Asia (RIP NCC) on September 14, 2012, Latin America and the Caribbean (lacnic) on June 10, 2014, and North America on September 24, 2015.
Until now, the NCC of Europe’s Rip (World Internet Organization) has run out of storage.
Maybe it’s an opportunity for manufacturers and IOT industry!
To remind everyone around you to stay away from the procedural apes around you.
