IPv6 is not mysterious, in fact it is just a network address encoding method. However, although there is no difference between IPv6 and IPv4 in terms of experience, in fact, IPv6 has unparalleled advantages in IPv4 regardless of its own attributes or applications: 1. Almost unlimited Compared with IPv4, currently IPv6 can be used almost unlimitedly. According to the reporter, the length of the IPV6 address is 128 bits, and the address space has been increased by 96 times. IPv6 can provide more network addresses for current and future Internet applications. It can add roughly 340 trillion trillion trillion IPv4 network addresses to the current 4 billion IPv4 network addresses. 2. Everything can be coded The infinite adequacy of IP addresses means that in the human world, each item can be assigned an independent IP address. The adoption of IPv6 has brought the information age from human-machine dialogue to the era of machine-to-machine interconnection, making the Internet of Things a reality. Due to the huge number of addresses, even a grain of sand can have its IP address. This means that all furniture, TVs, cameras, mobile phones, computers, cars ... all can be included as part of the Internet. 3. The death of network viruses 4. Online real-name system is feasible An important application of the popularization of IPv6 is the Internet ID card under the network real-name system. An important reason why the current IPv4-based network is difficult to realize the network real-name system is because of the sharing of IP resources. Because IP resources are not enough, different people share an IP at different time periods. IP and Internet users cannot achieve one-to-one correspondence. Under IPv4, operators only keep online logs for about three months. For example, users who check posts from an IP in the previous year cannot do so. However, the emergence of IPv6 can technically solve the problem of real-name system once and for all, because IP resources will no longer be tight at that time, and operators have enough IP resources. At that time, when operators accept applications for network access, they can directly give them The user assigns a fixed IP address, so that the real-name system is actually implemented, that is, a real user corresponds to an IP address one-to-one. When an Internet user's IP is fixed, everything the user does on the network is well documented at any time. Air conditioner Contactor is mainly applicable to a line of AC 50Hz or 60Hz,rated working voltage up to 600V and rated working current up to 60A,used to close or switch off the line.The Coil Insulation is Class B(130℃),can be operated with 85% of nominal coil voltage or 110% maximum safe operate.

Currently, viruses and Internet worms are the most troublesome cyber attacks. However, this propagation method is no longer applicable in IPv6 networks, because the IPv6 address space is too large. If these viruses or worms also want to scan the address segment to find other hosts with opportunities to take advantage of , Just like finding a needle in a haystack. In the IPv6 world, it is impossible to conduct network reconnaissance on IPv6 networks similar to IPv4 according to IP address segments. Therefore, in the IPv6 world, the spread of viruses and Internet worms will become very difficult.
