1. The background
IPv6 is short for Internet Protocol Version 6. IPv6 is a next-generation IP protocol designed by the Internet Engineering Task Force (IETF) to replace the current version of the IP protocol (IPv4). IPv6 extends the address length of IPv4 from 32 bits to 128 bits. Make address space enlarged 79228162514264337593543950336 times. With IPv6, every grain of sand in the world can be assigned an IP address.
IPv6 was designed to solve the problem of IPv4 address exhaustion, as well as significantly improve and eventually replace IPv4. However, due to the wide application of NAT and other technologies, IPv4 has dominated the Internet traffic for a long time, while the use of IPv6 grows slowly. It wasn’t until July 2017 that the percentage of users using Google services over IPv6 exceeded 20% for the first time.
As of press time, Google’s IPv6 stats
The General Offices of the COMMUNIST Party of China Central Committee and The State Council issued the Action Plan for Large-scale Deployment of Internet Protocol Version 6 (IPv6) on Nov 26, 2017. The plan points out that accelerating the large-scale deployment of IPv6 and building a high-speed, universal, full coverage and intelligent next generation Internet are urgent requirements for accelerating the construction of a network power, accelerating the process of national informatization, promoting economic and social development and winning new advantages in the future international competition.
On May 2, 2018, the ministry said: the Ministry of Industry and Information Technology on the implementation of the “promoting Internet protocol version 6 (IPv6) scale deployment plan of action to inform against the provinces, autonomous regions and municipalities directly under the central government, communications administration at various levels, as well as the four major operators and BAT represented by a series of enterprise reform in order to put forward the detailed work plan and.
At the same time, with the gradual maturity of 5G and IOT technology, the era of the Internet of Everything is coming, and the requirement of Apple AppStore to fully support IPv6, the voice of IPv6 is increasing in the market.
Therefore, from the perspective of policy orientation, market demand and technological evolution, 2018 is bound to be the first year of the explosion of IPv6 in China.
Today, we are very pleased to announce that Aliyun SLB has taken the lead in supporting IPv6!
2. Aliyun SLB IPv6 solution for load balancing
Ali Cloud SLB provides a new IPv6 instance, which has an IPv6 public address and can be accessed by IPv6 clients on the Internet. At the same time, ali Cloud SLB IPv6 solution has the following features:
1. Migrate services from IPv4 to IPv6 painlessly and smoothly. As shown in the figure above, the IPv6 SLB can directly mount ECS using IPv4 addresses, which means that users can migrate services to IPv6 painlessly and smoothly without modifying the original system. In addition, the new IPv6 entrance has no impact on the original IPv4 services. You only need to expand the back-end ECS horizontally when the total number of services increases.
2. IPv6 access control makes service deployment more secure and reliable alicloud SLB supports IPv6 access control. The access control blacklist effectively blocks the access of malicious addresses to load balancing services. The access control whitelist allows only IP addresses authorized by the whitelist to access load balancing services.
3. How do I purchase an SLB IPv6 instance
Currently, IPv6 is online in Hangzhou Region, and the invitation letter has been sent to some users. Users who have not received the invitation can apply for whitelist purchase through work order.
Let’s take a look at the purchase process for aN IPv6 instance:
1. Go to the SLB product purchase page
2. Choose East China 1(Hangzhou)Region; Select EC-1 AVAILABILITY zone F or EC-1 availability zone E for the primary availability zone, and ec-1 availability zone E or EC-1 availability zone F for the secondary availability zone. Note that currently, IPv6 sales are only available in F and E of East China 1
3. Select an appropriate instance specification, such as standard type I(SLB.s2.small). Note that currently only performance guaranteed instances support IPv6
4. Click “Buy Now”, and you can see that the IPv6 instance has been created in the console
On the access control menu, when you create an access control policy group, the IP version option is displayed. You can select IPv6 to create an IPv6 access control policy group
Other configurations are the same as those of the IPv4 SLB. For details, see the SLB product Help document.
4. Activity notice
In response to the national call to vigorously promote IPv6, Ali Cloud SLB will launch a major discount for IPv6 in the near future, please look forward to it, thank you for your support, see the next article.
