How to disable IPV6 tunnel in Windows 7

To disable IPV6 tunnel in Windows 7, IPv6 tunnel encapsulates IPv6 packets in IPv4 packets so that IPv6 packets can communicate through IPv4 networks. For devices using tunnel technology, IPv6 datagram is encapsulated into IPv4 at the entrance of the tunnel. The source and destination addresses of IPv4 packets are the IPv4 addresses at the entrance of the tunnel and at the exit of the tunnel respectively; at the exit of the tunnel, the IPv6 packet is taken out and forwarded to the destination node. Tunnel Technology only requires modification at the entrance and exit of the tunnel. It is easy to implement because it has no requirements on other parts. However, tunnel technology cannot directly communicate with IPv4 hosts and IPv6 hosts. The main difference between configuring tunnel on www.2cto.com and automatic tunnel is that automatic tunnel is feasible only when the IPv6 address of the node that executes the tunnel function is IPv4 compatible. When creating an I P address for the node that executes the tunnel function, the automatic tunnel method does not need to be configured. The tunnel method requires the tunnel end node to use other mechanisms to obtain its IPv4 address, for example, the configuration mechanism of d h c p, manual configuration, or other IPv4 is used. If you are using a notebook and often debug the network. In WINDOWS 7, an IPV6 tunnel is automatically created. Usually we can see many tunnels using ipconfig/all. For example, if I have more than 40 tunnels and want to view IPv4 information, it will flash and cause inconvenience to use. This is because one or more IPv6 transition technologies are required for windows during IPv6 migration. You can manually disable the IPv6 tunnel. Run the following three commands to disable the IPv6 interface: netsh interface teredo set state disable netsh interface 6to4 set state disabled netsh interface isatap set state disabled if you want to restore the IPv6 tunnel:: www.2cto.com netsh interface teredo set state default netsh interface 6to4 set state default netsh interface isatap set state default
