About IPv6 protocol settings for Win7 system

I believe everyone knows IPV4. If you know it, IPV6 is not difficult to understand. For the Internet, 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 Let me introduce you to everyone.

Every computer must have IP?

First of all, why should every computer have its own IP? Is it not okay? Let’s just say, the IP address is like you. The computer's "door number", only with this "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, which is also true 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?

Someone who knows a bit knows that the existing network protocol (IPv4) uses a 32-bit address, although it counts 232. (4294967296) addresses, but the number of demand is not too much, perhaps not until 2012, the Internet's IP address has reached the "end of day".

What is IPv6? Is it useful?

If you have a Windows 7 system installed, you may have noticed that there are already many Windows 7 systems in the "Internet Protocol". A "TCP/IPv6", and whether to turn off this option has become a problem that many users are entangled. Master Dong told you the correct answer today —— no!!

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 I have to admit that this is very professional, and it is a long story. If you understand it well, hehe), at the same time strengthen 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 not at all, then the latter, I believe that users who use the Windows 7 system to build a LAN will feel very obvious! Compared with XP, access to the LAN often appears to be stuck. In Windows 7, the feeling of accessing the LAN can be described as fluently, and using the group settings such as the family group, file sharing is also very convenient!

Introduce here, if you are interested, then find out, IPv6 has some other improvements, but to remind you that you may see some articles saying that IPv6 in Windows 7 system is turned off. How is the agreement, but what you want to tell is —— don't close IPv6, be brave enough to accept new things!
