IP is a network layer protocol that transmits data according to the addresses of the source host and the destination host. IP address is a concept in IP protocol. It's just as important as the doorplate address when you send a letter.
The full name of IPv6 is Internet Protocol version 6. Internet Protocol is translated as "Internet Protocol", and IPv6 is the sixth version of Internet Protocol.
At present, the network technology revolution has accelerated. IPv6, 5G, artificial intelligence, cloud, Internet of Things and other advanced network technologies have been innovated rapidly, and various network technology projects and open source organizations have developed rapidly, among which IPv6 has become a high-frequency word at the meeting. The advantage of IPv6 is that it can greatly expand the available space of addresses. Taobao has started to use IPv6 to solve the network congestion problem during the "Double 11" holiday. China's Internet will face the problem of unsustainable development due to the lack of new addresses. "So in the face of the technology improvement of large-scale Internet transaction services, we have done a lot of work, one is to promote the rapid deployment of IPv4 to IPv6, the other is to use various technologies to optimize user experience." Liu Dong, director of the National Engineering Center for the Next Generation Internet, said. Advanced network technology will bring a new era of subversive network. Wu Hequan, academician of the Chinese Academy of Engineering and chairman of the China Internet Association, said that the 5G design fully considered the integration of communication computing cache, adapted to the transmission of big data, including promoting the development of IPv6.
With the depletion of the existing IPv4 addresses, IPv6 has become the next generation IP protocol to replace the current version of the IP protocol (IPv4), which solves the problem of IP address resource shortage.
The length of IPv6 network address is 128 bits. It has a capacity of tens of billions of addresses, which is said to be able to "equip every sand of the earth with an IP". It greatly expands the available space of addresses.
After using IPv6, each device can have an independent IP address. If the 5G network is used, each car, street lamp, trash can and fire hydrant can have an independent IP address. The rich addresses of IPv6 make it possible to popularize the "Internet of Things".
In addition, IPv6 can also greatly reduce network latency, and the speed and security of the ipv6 network will also be improved. With the standard encryption option, it is difficult to crack the communication between users and servers.
IPv6 conversion services are cost-effective, support multiple protocols, and map rules take effect quickly, which can effectively save enterprise deployment time and development costs. As long as the existing business has an IPv4 public network address, Shangpin China IPv6 service can be used to support the IP of non Shangpin China website construction.
Through IPv6 conversion services, servers with public IPv4 addresses can quickly provide access services to IPv6 network side users.
For regular websites, select IPv6 conversion basic universal version. After transformation, it can support accessing and obtaining services through IPv6 protocol.
For government websites, IPv6 conversion is required to upgrade the government version. For the IPv6 transformation of government websites, the skylight problem caused by the external chain can be completely solved, and the transformation can meet the Verification Standards for IPv6 Transformation of Government Websites.
The first is expansion and evaluation. These works have been completed by combining the industry and the Internet community, especially the Internet registration management agencies in relevant regions.
The second is to set an example. The government also lets some departments or institutions take charge of this matter, and ensures that these departments or institutions have sufficient rights and have obtained cooperation and support from other institutions. They also developed reports and standards or measures, and set up a working group to respond to these issues - especially with regard to ensuring the continuity of government services during the transition to IPv6. Some governments have also begun to implement IPv6 on departmental or institutional networks
IPv6 is an inevitable trend of Internet development. Governments at all levels, state-owned enterprises and public institutions are gradually switching to use IPv6.
Compared with IPv4, IPv6 has the following advantages:
1. "Massive" network addresses: IPv6 can provide "foreign" network addresses, which are far more than IPv4. There are 128 addresses to the power of 2 in total. The huge amount of data makes every grain of sand have its IP address.
2. Network real name system is feasible: another important application of IPv6 popularization is Internet identity authentication under network real name system. An important reason why IPv4 is difficult to implement: insufficient IP resources lead to different people sharing the same IP at different times, and the IP address and Internet users cannot correspond one by one. Due to the emergence of IPv6, operators can assign a fixed IP address to each user who applies for network access, and users' online behavior or records at any time will be well documented.
3. Faster content acquisition speed: IPv6 address allocation follows the "clustering" principle at the beginning, greatly reducing the length of the routing table, and greatly accelerating the speed of the router to forward packets and acquire content.
4. Realize the security of the IP layer: IPv6 can realize the security of the IP layer. Users can encrypt the data of the network layer and verify the IP message while ensuring the integrity and confidentiality of the packet. IPv6 incorporates IPSec into its architecture, allowing IPSec to be embedded directly in IPv6 packets. This feature can ensure users' information security.
5. The multi hosting feature supports 5G applications: typical IPv6 devices can have multiple addresses, and a terminal can establish the function of multiple hosts at the same time, providing mobile edge computing with source address based streaming applications.
6. No matter what operating system, whether Apple or Android, all support IPv6. It seems that there is no change, but the Internet has undergone tremendous changes at the same time.
Shangpin China website construction has cooperated with Alibaba Cloud for many years and provides dual stack servers that support ipv6 access. After purchase, users do not need professional technical deployment. They can simultaneously enable IPv4 protocol stack and IPv6 protocol stack, and can communicate with IPv4 network&IPv6 network at the same time.
