How different is IPv6 than IPv4 with a 2 added

At present, driven by various new technologies such as 5G, big data and cloud computing, the development of the Internet has also become fast.But along came an explosion in demand for IP addresses.IP addresses are not enough.In particular, with the rapid development of the Internet of Things, the industrial Internet and 5G, the corresponding IPv4 address allocation is running out.So, the new generation of Internet protocol IPv6 becomes critical.There’s been a lot of good news about IPv6 these days.By the end of last year, 607.7 million active IPv6 Internet users had reached China, accounting for 60.10% of the country’s total Internet users, according to the latest statistics.So what’s different about IPv4 and IPv6, and what does it matter to us?In fact, the Internet, which we are now inseparable from each other, was first created in the 1960s.At the heart of the Internet’s ability to exchange information is the well-known Internet Protocol (IP).To put it bluntly, the Internet is like a delivery company.The IP address is your delivery and delivery address.The items to be sent and received are all kinds of text, pictures, audio and video, data and other file information.The IP protocol is the “workflow and system” of the express company.After the Internet largely matured, the most widely deployed and longest-used IP protocol was version V4, also known as IPv4.However, because IPv4 uses 32-bit binary numbers, its addresses are 32 bits, so the number of addresses it can provide is: 2^32-1, or about 4.3 billion.However, not all addresses will be assigned.Some addresses need to be reserved, or used for broadcasting, testing, private network use, etc.These addresses are often referred to as special addresses in the industry.That would be good enough to have about 4 billion addresses to distribute.But now, with the rapid growth of the Internet, mobile, and the Internet of Things and the industrial Internet, the four billion addresses available in this protocol may seem like a lot, but not enough.Even if the world’s 7.5 billion people were given just one IP address each, an IPv4 address would not be enough.What’s more, everyone has more than one internet-connected smart device.Phones, computers, tablets, smart wristbands, watches, wearables — everyone has a few.If plus intelligent speaker, intelligent home and so on much.And that’s just for individual users.If you include the industrial Internet and iot applications in some vertical industries, the number of IP addresses required is even higher.Therefore, the exhaustion of IPv4 network address resources seriously restricts the application and development of the Internet.So the next generation of Internet protocols, IPv6 and IPv6+, have emerged.IPv6, in short, is version 6 of the IP protocol.IPv6+ is an upgraded version of IPv6.IPv6 uses 128-bit binary numbers to represent network IP addresses.So, the number of addresses it can provide is 2^128-1, or about 340 trillion.Therefore, IPV6 address resources can become quite rich.It claims to be able to address and assign its own IP address to every grain of sand on earth.In the past, the Internet started late in China and only 290 million IP addresses were allocated in IPv4, so they only shared public IP addresses.The most immediate effect of this is slower network response time and latency.With IPv6, every connected device now has its own IP address, making networks much more responsive.Still use express company to describe compare IPv6 and IPv4.IPv4 express delivery company, due to the user’s address is not enough, so the Courier often can not come to the door to send and receive items for users.It can only be sent to the user by the gatekeeper or the transit agency such as the express cabinet and the Courier station.With IPv6, each user has his or her own address, so the Courier can directly deliver the package to the user.Obviously, with IPv6, the express company not only improves the speed of sending and receiving express, but also saves the expenses and maintenance of the transit agency.In addition, cutting out the middle of secondary delivery also makes sending and receiving items more responsive, with greater security and confidentiality.Especially in the Internet of things, the Internet of vehicles and industrial Internet, more need end-to-end direct, have lower latency, faster response and higher security, the benefits of IPv6 will be more apparent.IPv6+, based on IPv6, has even more innovations.For example, there are protocol innovations represented by IPv6 segmented routing, network slicing, on-stream detection, new multicast and application-aware networks, as well as technological innovations represented by network intelligence such as network analysis, automatic tuning and self-healing.With these innovations, IPv6+ is more suitable for industrial users and can better support industrial users, industrial Internet and Internet of Everything applications.IPv6+ accurate identification of packet attributes can also help operators better understand the flow trend of data services in the entire network, and better mobilize and allocate resources.Or express company to describe, like when the use of IPv6+ express company found from A to B express transfer volume increased, especially large goods, can immediately plan A special capacity and lines to receive and send service users.It is worth mentioning that iN terms of security defense and security capabilities, IPv6 and IPv6+ are also greatly improved over IPv4, truly realizing the integration of cloud, network, and security defense.On traditional IPv4 networks, public IP addresses are shared because IP addresses are insufficient.Therefore, there must be a large number of private networks.Therefore, some hackers also use this natural vulnerability to send malicious data to the public network.With IPv6 and IPv6+, each device has its own IP address, which eliminates this natural vulnerability.For example, the user and express company through the guard or express ark, register post secondary transfer, delivery, transfer institutions, such as criminals in the intermediate link to add, replace, something in the parcel, or with the aid of transit agencies access to the user address, it’s often difficult for users to send malicious data such as the behavior has been found.Once users receive or open these packages with malicious things, they will often suffer losses.But with IPv6 and IPv6+, there is no secondary forwarding, so the security of the package is obviously much higher.In addition, IPv6’s 128-bit binary number also makes the data packet structure richer, which can record more content and information, making it more difficult for hackers to fabricate and eavesdrop on packets.This also enhances the security and privacy of packets.Therefore, the development and application of the next generation Internet based on IPv6 and IPv6+ is obviously a quite good choice.All in all, IPv6 and IPv6+ are a faster, more efficient and flexible Internet protocol system.Both individual and industry users will benefit from using it.At the same time, IPv6 and IPv6+ will better adapt to the needs of different users and industries, meet the differentiated service capabilities of thousands of industries and industries, and support the digital transformation and development of the whole society.So, do you now understand the difference between IPv6 and IPv4?
