Analysis of IP address and the setting of IPV6 protocol under Win7

If your computer IP address is the same as the IP address of the other computer in the local area network, a conflict will occur. Today deep XP system download station and you talk about IP issues, and how to set the Windows7 IPV6 protocol.

Does every computer need to have IP?

First of all, why does every computer have its own IP? No, no, no, no, no, no. So to speak, IP address is like your computer "number", only with this "number", other users and computers can find your computer. You said to the other computers, "turn left, turn left, turn left, then turn left" is definitely invalid.

In the LAN, each computer has an IP, also in the Internet as well. But the number of users of the Internet is not comparable to the local area network, so the problem arises-with the rapid popularization of the Internet, more and more people joined the "net", but the existing IP protocol is almost not enough to accommodate so many people!

Anyone who knows a little about it, the existing network protocol (IPV4) uses 32-bit address, although it has 232 (4294967296) address, but compared to the number of demand is not much, perhaps not until 2012, the Internet's IP address has reached the "end".

What's IPv6 for?

If you install the Win7 system, you may have noticed that there is already a "Tcp/ipv6" in the Windows 7 System "Internet Protocol," and that turning off this option is a problem for many users. Small series suggest everyone--------Not shut!

IPv6 is precisely to solve the problem of IPV4 address will be depleted of the emergence of the issue. It uses 128-bit address length, so there are 2128 (interested friends can calculate, hehe) address available! Yes, the new IPV6 address can be said to be unlimited compared to IPV4! Therefore, the IP address problem in the IPV4 protocol will no longer be a problem in the IPV6 protocol.

In addition to solve the problem of insufficient number of IP addresses, IPv6 for ordinary users, the biggest improvement is to further improve the security (network layer data encryption and IP message verification.) At the same time, strengthen the management of local area network, make it more convenient and fast.

If the former has improved security and security, the feeling is not obvious or completely not feeling, then the latter, believe that the use of Windows 7 system to build a local area network users will feel very obvious! Compared to XP, access to the LAN often occurs, In Windows7, the feeling of access to the LAN can be described with the carefree dripping, and the use of family groups, such as group settings, file sharing is also very convenient!

In addition to the above, IPv6 there are other aspects of the improvement, here is no longer to repeat. But need to remind of IS, do not close IPv6, must dare to accept new things!
