6to4 Adapter is basically just a virtual adapter which microsoft has developed to change the IPv6 to IPv4 internally.
There is some compatibility issue with Vista and so it keeps on showing these errors and warnings. Also a 6tOP adapteer keeps on getting created
To stop the 6TOP adapters being created we have to remove the problem. this is cause by network adapters not having matched ipv4 and ipv6 settings. This is where the 6TO4 adapter comes in to play, it translates between IPV4 and IPV6 but because of the issues caused by Vista it keeps on creating them.
- check all adapters have IPV4 and IPV6 enabled or disable all IPV6 in adapters
- then delete all the erronoues drives 6to4 and isatap if required
Other Things to Try
- Uninstall any ADSL modem drivers or other network adpaters
- check other adaptors settings do they have ipv6 enable. ie if they dont a tunnel adaptor 6to4 will be created. if there are incompatability issues one might be created every connection
- update speedtouch drivers + all other network drivers
It's not used so no it's not important. Do the following:
- Go to the Control Panel and select Network & Sharing center.
- Click manage network connections and disable your dial up/broadband if you use wireless. Disable wireless if you use dial up/broadband.
- Right click your network connection and then left click properties.
- Uncheck the Internet Protocol Version 6 (TCP/IPv6)
- Click OK and exit.
This will eliminate connection/hangup issues as well.
If you are not sure google IPv6 6to4. It basically works with how ip addressess are issued, and we won't be needing it any time soon. For example:
IPv4: 4,294,967,296 addresses (what we use now)
IPv6: 340,282,366,920,938,463,463,374,607,431,768,211,456 addresses. (what we'll use in the future)
