These adapters are part of the Microsoft implementation of the iPv6 TCP/IP address protocol. You will find you have quite a lot of them, at least one per each defined network adapter. You also probably have VMware player installed, which adds several network adapters potentially used by virtual machines.
These dummy adapters are called "Automatic Tunneling Pseudo-Interface" for encapsulating IPv6 packets with an IPv4 header so that they can be sent across an IPv4 network. This probably means that your local network is at the moment both iPv4 and iPv6, and these adapters are created "just in case".
If you are working on a local network, you have no need of iPv6, since 4-byte TCP/IP addresses are quite sufficient for the number of computers. To get rid of these dummy adapters do:
- Open up Control Panel -> Network and Sharing Center.
- For each network connection :
- Click "View status", then Properties.
- Uncheck the mark next to "Internet protocol version 6 (TCP/IPv6)".
- Click OK, then Close.
- When all adapters are done, reboot.
This will leave only iPv4 interfaces defined on your computer, and will only work if you do not have any pure-iPv6 device on the local network. If you do have such a device, you will need to allow iPv6 at least on the one network adapter on which it communicates.
