How does Windows XP configure IPv4 as IPv6

With the continuous growth of the Internet, the demand for IP addresses is increasing, resulting in stricter IP address distribution. Many users who have been using WinXP IPv4 already hope to use it. Configured as IPv6, that is, the number of IPv4 address bits is 32 bits. IPv6 has a larger address space, which greatly enhances the security of the network. Therefore, many netizens are seeking such a configuration strategy. Let's explain the configuration process in detail.

Preparation: First, you need to ensure that at least WinXP system upgrade to SP1. Secondly, you must have IPv6 installed on your WinXP system.

The configuration process is as follows:

1. Install IPV6 protocol

C:\\>ipv6 install

2, view port information

First use the ipv6 if command to view the status of each interface. In general, you will see the following display:

Interface 4 (site 1): Local connection

……

Interface 3 (site 1): 6-over-4 Virtual Interface

……

Interface 2 (site 0): Tunnel Pseudo-Interface

……

Interface 1 (site 0): Loopback Pseudo-Interface

……

Interface 4 is the local real port, the other three are Virtual port, notable is Interface 2, which is the port of Auto-Tunnel, which we need to use in the access configuration.

3, if it is in a pure IPV6 network (or IPV6 and IPV4 dual-stack network), you can automatically get the IPV6 address, you can access the IPV6 website.

You can also set a fixed IPv6 address as follows:

C:\\>netsh

netsh>interface ipv6

netsh interface ipv6> Add address "local connection" fe80:a520:1314::1

/* Set a fixed IPv6 address, "local connection" refers to the name of a connection established on your machine* /

netsh interface ipv6>add dns "local connection" 2001:251:e101:0::2

/* Set IPv6 DNS address*/

4. If you are on an IPV4 network, you need to tunnel with the IPV6 network. A tunnel needs to be established by the peer user. The peer can be a route (switch) of the network center or another PC. In any case, the following information is required:

Your IPV4 address that can be routed to the peer is assumed to be 210.35.168.100

The IPV4 address of the peer is assumed to be 210.35.240.24

The IPV6 address of the peer is assumed to be 2001:250:6C01:1000::1

The IPV6 address assigned to you by the peer is assumed to be 2001:250:6C01:1000::2

The local configuration is as follows:

Configure the tunnel: ipv6 ifcr v6v4 210.35.168.100 210.35.240.24

Configure the ipv6 address for this machine: ipv6 adu 4/2001:250:6c01:100 ::2

Note: The address of the 4th Interface port is set to 2001:250:6c01:100::2. In this configuration, it is generally specified as the actual Interface number. If there is only one network card. If it is, it should be Interface #4. */

Configure routing for this machine: ipv6 rtu ::/0 4/2001:250:6c01:100::1

If the peer (server) is a network center, please Look at the router configuration. If the peer is also a PC, depending on the system, configure it according to the configuration method of each operating system listed in this site.

5, if you want to use WindowsXP as a router, you also need to open the forwarding function of other interfaces. For example, if interface 4 is your network card, your local area network is hung under this network card, then you You also need to turn on its forwarding function: ipv6 ifc 4 forwards

Depending on your needs, you may also want to turn on the route broadcast feature for some interfaces.

6, test:

Ping the peer address of the tunnel, the ping can be configured successfully.

ping 2001:250:6c01:100::1

With the above 6-step configuration, your WinXP will successfully transition from IPv4 to IPv6. Of course, the recent emergence of IPv9 has also been domestically The pursuit of many users, it can be said that the Internet is also constantly improving, but for the current WinXP users, IPv6 is enough for most users to use, I believe this tutorial will be very helpful for some friends.
