Details of the commercial use of IPv6

In short, IPv6 in addition to the abundant number of IP addresses, IPv6 has many other advantages over IPv4, with faster transmission speed, fast, faster, very fast, this is now the long-term pursuit of the Internet, and IPv6 is a fixed header, not like IPv4 carries a bunch of lengthy data, short header to improve the efficiency of network data.

And because the IPv6 routing table is smaller and the aggregation capacity is stronger, the path of data is shorter, which greatly improves the efficiency.

Currently, there are three strategies and transition technologies to achieve the coexistence of IPv4 and IPv6.

First, use dual stack to allow your host or network device to support both IPv4 and IPv6 dual stacks. Second, IPv6 packets are encapsulated in IPv4 packets through tunneling technology. Third, IPv6 packets are converted into IPv4 packets and vice versa via Network Address Translation (NAT) technology.

Dual-stack technology is an effective technology for the transition from IPv4 to IPv6, and its nodes support both IPv4 and IPv6 protocol stacks, and use IPv6 protocol stacks when IPv6 nodes communicate with IPv6 nodes, and use IPv4 protocol stacks with IPv4overIPv6 tunnels when communicating with IPv4 nodes, so as to realize information exchange with IPv4 or IPv6 nodes respectively through this technology.

Dual-stack can be implemented on a single device, or it can be a dual-stack backbone network, what is a dual-stack backbone network? That is, all devices support IPv4 IPv6 protocol stack at the same time, connect to the decontrol of dual-stack networks, and configure IPv4 addresses and IPv6 addresses.

IPv6 support means that this software or ** allows users to use IPv6 networks to access applications. The characteristics of IPv6 should be like this, and it is precisely this feature that enables IPv6 to gradually replace IPv4.

1. For IPv6 addresses, its length is 128 bits, so that the corresponding address space has increased from the original number of 2 128-2 32.

2. IPv6 also has a very flexible format for IP packet headers. Typically, a series of fixed-format extension headers are used to replace some of the variable-length option fields in IPv4. There are also changes in the appearance of the options in IPv6, so that the router can easily pass by this option and do not do any processing, which improves the packet processing speed by a large extent.

3. In terms of IPv6, it simplifies the format of the corresponding packet header, and the corresponding fields only contain 8, so that the corresponding packet ** will be very fast, and the corresponding throughput will be improved.

4. This IPv6 can also continuously improve security. Authentication and privacy are one of the most critical features of IPv6.

5. IPv6 can support many service types.

The R&D company for IPv6 is IETF:

The corresponding full name is Internet Engineering Task Force. The company designed IPv6 to replace the popular version of IPv4. But why replace?

This is mainly due to the increasing number of computers, tablets and other related electronic products.

Youzhao IPv6 is more secure, and the standard state is equipped with encryption options, so the communication between the user and the server is difficult to crack. In addition, IPv6 can greatly reduce network latency, which can be reduced from about 100ms to single digits.

The use of IPv6 can not only solve the problem of the number of network address resources, but also solve the obstacles of multiple access devices to connect to the Internet; IPv6 is used because IPv4 network address resources are insufficient, which seriously restricts the application and publication of the Internet.
