Tips for turning off IPV6 tunnels under Windows 7

        An IPv6 tunnel encapsulates IPv6 packets in IPv4 packets and allows IPv6 packets to communicate through the IPv4 network. For the tunneling device, the IPv6 datagram is encapsulated into IPv4 at the entrance of the tunnel. The source and destination addresses of the IPv4 packet are the IPv4 address of the tunnel entry and the tunnel exit respectively. At the exit of the tunnel, Then forward the IPv6 packet to the destination node. Tunneling technology only requires modifications at the entrance and exit of the tunnel. It is not required for other parts and is easy to implement. However, tunneling technology cannot achieve direct communication between IPv4 hosts and IPv6 hosts.

Configured tunnel and automatic tunnel main difference is: only perform the function of the node tunnel IPv6 address is IPv4-compatible addresses to automatically tunnel is feasible. The automatic tunneling method does not need to be configured when establishing an IP address for the node performing the tunnel function. The tunneling method requires the tunnel end node to use other mechanisms to obtain its IPv4 address, for example, using DHCP, manual configuration, or other IPv4 configuration mechanism.

If everyone in the notebook, often commissioning network of words. WINDOWS7 will spontaneously establish an IPV6 tunnel. Usually we will see a lot of tunnels with ipconfig/all. For example, there are more than 40 tunnels on my side. If you want to see IPv4 information, it will flash over and cause inconvenience. . This is because Windows needs to use one or more IPv6 transition technologies during the IPv6 migration process. We can manually close the IPv6 tunnel.

We only use the following three command to turn off IPv6 interface can

netshinterfacetereDOSetstatedisable

netshinterface6to4setstatedisabled

netshinterfaceisatapsetstatedisabled

To restore the IPv6 tunnel with the following command:

netshinterfacetereDOSetstatedefault

netshinterface6to4setstatedefault

netshinterfaceisatapsetstatedefault
