Deep interpretation of the new Internet Protocol IPV6: Users do not need to adjust

Google said on its homepage: "The next generation of internet today unveiled" What if the Internet address is not enough? In fact, it is now on the verge of exhaustion. Wenter Sove, Google's chief Internet promotion officer, is also one of the fathers of the Internet, speaking of the new generation of the Internet (the IPV6 Internet) and why we need IPv6. Why is the Internet address not enough? Just as telephones use telephone number systems to call, each device connected to the Internet has a unique number called an "IP address" for connecting to the global online network. IP address is the phone number of a network device The problem is that the current Internet address system (ie IPV4) has only about 4 billion of the address space, even less than the world's population, and now and even future online devices (including computers, mobile phones, televisions, watches, refrigerators, automobiles, etc.) . There are now more than 4 billion devices sharing addresses, and as IPv4 's remaining address becomes scarce, everyone must share the address. So how do we extend the address space? Obviously, the Internet needs more IP addresses. So how much do you need? 340 trillion trillion should be enough? Yes, this is the number of addresses the new generation of Internet "pipeline system" IPV6 can provide. Such a large quantity is enough for everyone on earth to have billions of IP addresses, in other words, enough to provide unlimited address space for the development of the Internet in the present and foreseeable future. IPV6 can provide an almost unlimited number of IP addresses, IPV4 can only provide 4 billion (note: the figure written "400 million Yuan", may be wrong, Google may not understand the Chinese capital digital expression) when will this transition take place? It would take some time to replace the "pipeline system" for the entire internet. June 6, 2012, the major web sites and Internet services and equipment providers to jointly enable IPV6, which marks the official launch of IPV6 on a global scale. Google believes that IPV6 is critical to the continued healthy development of the Internet, and that IPV6 can facilitate the development of innovative services by allowing all devices to communicate directly with each other. Global IPV6 Deployment FAQ 1, IPV4 and IPv6 what are they? IPV4 is the current version of the Internet Protocol, and the Internet Protocol is the identity system used by the Internet to send information between devices. The system assigns a sequence of four digits (each number is between 0 and 255) for each device. IPV4 can only provide about 4 billion addresses, which cannot meet the needs of the Internet. IPV6 is a new version of the Internet Protocol that can provide an almost unlimited number of addresses: 340 trillion megabytes. 2. Why is IPv6 so important? IPV4 address has been unable to meet the needs of the Internet, transition to IPV6 can allow the Internet to continue to develop and promote new innovative services development, because there are more equipmentCan connect to the Internet. 3, what is the IP address? Just as you can use a phone number to talk to other phone calls, providing your computer with an IP address (an acronym for Internet Kyoto Address) allows it to communicate with Web sites, Internet services, and other devices. An IP address is a string of letters or numbers, such as 192.0.2.1 (IPV4) and 2001:db8::1234:ace:6006:1e (IPV6). 4, what is IPV6 Global launch (World IPv6 Launch)? The IPV6 global launch is organized by the Internet Association, which is scheduled for June 6, 2012, and the major websites and Internet service providers (ISPs) participating in the day will be able to permanently enable IPV6 and begin IPv4 transition. 5. What's the difference to me? What do I need to do to prepare for the job? You do not need to be prepared for IPV6, and your applications and equipment can still be used as normal as before. This change is meant to ensure that you continue to use the Internet as you do today. 6. How long will the transition take? A full transition from IPv4 to IPV6 takes time because all Web sites and Internet service providers need to be transformed. During this time, the two systems will work in coordination until no longer requires IPv4. 7, IPV4 can not be used again? No, the IPV4 service can still be used normally. 8. Have I already used IPv6? You may already be using IPV6 to access ipv6test.google.com for confirmation. Many of the devices you use already provide IPv6 support, but to use IPV6, if you visit a Web site and your Internet service provider has enabled IPV6 first. 9, I have not yet used IPv6, how to use? Many large web sites and Internet service providers now offer IPV6 support, but there are more web sites and providers that need to be transformed. If you are using IPV6, you can request IPV6 Internet access from your Internet service provider. You may also need to enable IPV6 on your home router or upgrade to a home router that supports IPV6.

Version 5 has been reserved for Internet information flow protocols developed prior to IPV6, never widely deployed and not publicly available. Turn from: google
