Hello B. Addy,


Thanks for your post!


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


In some scenarios, there will be a code 31 or code 10 error appearing beside this component. A possible reason is, the network adapter doesn’t support this feature. You may update the driver for your network adapter or chipset, and then try to uninstall and reinstall the this component.


To uninstall the component, right-click the item in Device Manager and select Uninstall.


To reinstall the component, in Device Manager, Action – Add Legacy Hardware – Next – “Install the hardware that I manually select from a list” – Network adapters – Microsoft – Microsoft 6to4 Adapter – Next – Finish the wizard.


If the steps above doesn’t solve the problem, your network adapter is not a supportive one for this component. You can completely ignore this error, if there isn’t IPv6 network deployed in the environment. The error won’t affect your system.


To remove the error message, please right-click the Command Prompt and run as administrator, type the command netsh in 6to4 set state disable, press Enter. The component will be disabled and hidden.


Hope it helps!
