About IPv6 protocol settings for Win7 system

        I believe everyone knows IPV4. If you know it, IPV6 is not difficult to understand. For the network, this thing is both familiar and unfamiliar. I believe there are still many people who don't understand some of his functions. Today this tutorial is for everyone. Let me introduce it. Every computer must have IP? First of all, why should every computer have its own IP? Is it not okay? So, the IP address is like your computer's "door number", only This "number" number, other users and computers can find your computer. You said to other computers "Left turn, turn left, turn left, then turn left"; it is definitely invalid, huh, huh. In the LAN, each computer has an IP, as well as in the Internet. However, the number of users on the Internet is unmatched by the local area network, so the problem arises. —— With the rapid spread of the Internet, more and more people have joined this "net"; but the existing The IP protocol is almost ready to accommodate so many people! What to do? Some people who know a little about it know that the existing network protocol (IPv4) uses a 32-bit address, although it counts 232 (4294967296) addresses. But compared to the number of demand, it doesn't seem too much. Maybe it won't be until 2012, the IP address of the Internet has already reached the end of the day. What is IPv6? Is it useful? If you have a Windows 7 system installed, you may have noticed that there is an additional "TCP/IPv6" in Windows 7 system "Internet Protocol", and whether Turning off this option has also become a problem that many users are struggling with. Master Dong told you the correct answer today —— no! www.dnzg.cn IPv6 is precisely to solve the problem that IPv4 addresses will be exhausted. It uses a 128-bit address length, so there are 2128 (interested friends can calculate, huh, huh) an address is available! Yes, compared to IPv4, the new IPv6 address can be said to be unlimited! So IP in the IPv4 protocol Address issues will no longer be an issue in the IPv6 protocol. In addition to solving the problem of insufficient number of IP addresses, the biggest improvement of IPv6 for ordinary users is to further improve security (encryption of network layer data and verification of IP packets.), Master Dong has to admit that this is very Professional, and long-term, everyone knows, huh, huh), while strengthening the management of the local area network, making it more convenient and fast. If the former feels that the security and security are not obvious or completely unfeeling, then the latter, I believe that users who use the Windows 7 system to build a LAN will feel very obvious! Compared to XP, access to the LAN Frequently there is a stuck situation. The feeling of accessing the LAN in Windows 7 can be described as fluently, and using the group settings such as the family group, file sharing is also very convenient! Everyone introduces this, if you are interested, Let's find out, IPv6 has some other improvements, but to remind you that you may see some articles about how to turn off the IPv6 protocol in Windows 7 system, but tell you is — — Don't close IPv6, be brave enough to accept new things! Ha ha.
