IPv6 functions: 1. IPv6 uses 128-bit binary numbers to represent network IP addresses, which greatly increases the number of IP addresses and has a larger address space. 2. In ipv6, users can encrypt network layer data and verify IP messages; and ipv6 provides group confidentiality and integrity for data encryption and identification. These measures greatly enhance the network's security. safety. 3. IPv6 has a better header format, which simplifies and speeds up the routing process. 4. IPv6 adds new options and supports more additional functions.

What is ipv6
IP is the abbreviation of Internet Protocol (Internet Protocol). An IP address is generated according to the rules of the IP protocol. The IP address is The addresses of terminals such as mobile phones and computers on the Internet are the unique identities of terminals in cyberspace.
IPv6 is the abbreviation of Internet Protocol Version 6. It is the next generation IP protocol designed by the Internet Engineering Task Force (IETF) to replace IPv4. Its number of addresses is said to be the largest in the world. Every grain of sand in the world is encoded with an address.
IPv6 is a globally recognized next-generation Internet commercial application solution. It is a next-generation Internet protocol version developed by the International Organization for Standardization IETF to solve the exhaustion of IPv4 addresses. It can provide massive network address resources and broad space for innovation. .
The biggest problem of IPv4 is the insufficient network address resources, which seriously restricts the application and development of the Internet. The use of IPv6 can not only solve the problem of the number of network address resources, but also solve the obstacles for multiple access devices to connect to the Internet.
What are the functions of ipv6
1. IPv6 greatly increases the number of ip addresses and has a larger address space
ipv6 uses a 128-bit binary number to represent the network IP address, while ipv4 uses a 32-bit binary number. IPv6 is fully 4 times longer than IPv4. Moreover, the network address resources of IPv4 have been exhausted, which seriously restricts the application and development of the Internet.
The number of ipv6 addresses is said to be able to address every grain of sand in the world. It can be seen that ipv6 has greatly increased the number of ip address spaces. This is the biggest role of ipv6.
2. IPv6 greatly enhances the security of the network
In the IPv6 network protocol, users can encrypt network layer data and ip packets Verification; not only that, IPv6 provides packet confidentiality and integrity for data encryption and identification. These measures greatly enhance the security of the network.
3. IPv6 has a better header format, which simplifies and speeds up the routing process.
Different from IPv4, IPv6 uses options and basic headers Separate new header format. Where necessary, options can be inserted between the upper data and the base header.
Since most options do not require routing selection, this method can simplify and speed up the routing selection process.
4. IPv6 has added new options and supports more additional functions.
Since IPv6 has some new options, it can support more additional functions. accomplish.
To sum up
ipv6 is the next generation network ip protocol of ipv4. It has the following four outstanding functions, namely, greatly increasing the number of ip addresses and greatly enhancing Network security, simplifying and accelerating the routing process, and supporting the implementation of more additional functions.
