What is ipv6 network

The ipv6 network refers to a network based on the ipv6 protocol. ipv6 is version 6 of the Internet Protocol (IP Protocol). It is the next generation Internet protocol version developed by the International Organization for Standardization IETF to solve the exhaustion of IPv4 addresses. The ipv6 network is more secure, with standard encryption options, and the communication between the user and the server is difficult to crack; and IPv6 can greatly reduce network latency, which can be reduced from the current common 100ms to single digits.

The ipv6 network refers to a network based on the ipv6 protocol.

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 known as Every grain of sand in the world can be assigned 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. .

IPv6 is a network layer protocol for packet-switched Internet networks. IPv6 has a much larger address space than IPv4. This is because IPv6 uses 128-bit addresses, while IPv4 only uses 32-bit addresses. Therefore, the new address space supports 2 to the power of 128 (approximately 3.4 times 10E38) IP addresses. This extension provides flexible address allocation and routing and eliminates dependence on Network Address Translation (NAT). In the past, because IP addresses were limited, NAT was commonly used to reduce the consumption of IP addresses. Based on the earth's population of 7 billion people, each person can be allocated an average of about 4.86 times 10E28 IPv6 addresses.

The role of IPv6 network

There are tens of billions of devices in the world, but only more than 4 billion addresses. Since China's Internet started late, only 290 million IPs were allocated, so they are shared. It's okay to access the Internet normally, but it becomes very difficult to access a certain Internet device from the public network, such as checking your home camera or remotely controlling your computer. After switching to IPv6, each device can have an independent IP address. If combined with the 5G network, each car, street light, camera, mobile phone, trash can, and fire hydrant can have an independent IP address. With IPv6’s rich addresses, all devices can be assigned their own unique IP addresses, making the “Internet of Things” possible and all walks of life will benefit. As long as any device is assigned an independent IP address, it can be used at any time. Control anywhere, everything is connected.

Advantages of IPv6 network

IPv6 is more secure, comes standard with encryption options, and 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 the current common 100ms to single digits. Low network latency is not only helpful for gaming, it also makes remote drones and autonomous cars feasible. IPV6 avoids joint risks under shared IP conditions, that is, if other virtual host users on the same server are blocked due to attacks (such as DDOS), violations (such as pornography, gambling and drug abuse) or policy measures, they will not be implicated. Shared IP means that if a user has a problem, almost all users on the entire server will be affected. Such problems can only be solved by independent IP.

The emergence of IPv6 network

IETF began to develop the IPv6 protocol in 1992. In December 1995, it published the proposed standard (proposal standard) in RFC1883, and in July 1996 The draft standards of versions 2 and 2.1 were released in May and November 1997, and the standard RFC2460 was released in December 1998. IPv6 was born to solve the problems of the current Internet. There are two major crises lurking in the existing IPv4 network: address exhaustion and routing table expansion. The emergence of IPv6 will fundamentally solve these problems. IPv6 inherits the advantages of IPv4, and has been significantly modified and expanded based on the experience of running IPv4 for many years. Its processing performance is more powerful and efficient than IPv4. Compared with other technical concepts that have emerged during the development of the Internet, IPv6 can be said to be the least controversial one. People have reached a consensus that IPv6 replacing IPv4 is an inevitable development trend. The main reason is due to the almost unlimited address space of IPv6.
