Hundreds of "Microsoft 6to4 Adapters" and several "Microsoft ISATAP Adapters" in device manager and the number is growing

I got hundreds of "Microsoft 6to4 Adapters" and several "Microsoft ISATAP Adapters" in my device manager. It seems the number is growing also. These devices are hidden, thus it would be normally not noticed. I found this problem when I am using "ipconfig" command to check local ip address.

Does any have see similar problem? Is there a method to remove and fix the problem?

Hi minichocobo,

6to4 adapter is a component used for transmitting IPv6 packets trough IPv4 network correctly.

I suggest you completely uninstall the drivers and re-install it and check if the issue persists.

Refer the following link and follow the steps given by Lionel Chen – MSFT.

These drivers are installed by the updates on your computer, Check if you have the latest drivers installed.

If everything is working fine you may remove the old drivers.

I would also advise you to download the Network drivers from the manufacturer's website.
