What is the Microsoft 6to4 Adapter Windows Driver?
The Microsoft 6to4 Adapter is a virtual network adapter used to enable IPv6 (Internet Protocol version 6) connectivity over an IPv4 (Internet Protocol version 4) network. It's part of the 6to4 tunneling protocol, which allows IPv6 traffic to be encapsulated within IPv4 packets and transmitted over an IPv4 network. This is useful when an IPv6-enabled system is connected to a network that only supports IPv4.
This adapter is part of Windows' built-in networking stack and doesn't require a separate driver for most installations. Windows will automatically install the necessary driver when the 6to4 adapter is detected. However, in some cases, you may see the Microsoft 6to4 Adapter in Device Manager with a warning (yellow triangle), indicating an issue with the adapter or driver.
