I'm unable to see the 6to4/Teredo adapter anywhere in my Windows 7 installation. In my Device Manager, the only network adapters are my wireless Realtek card, and "TAP-Win32 Adapter OAS" which is for my OpenVPN.

ipconfig /all output:

How can I install/enable the adapter?

  • You do understand you already have both a IPv6 and IPv4 address right?

  • in the device manager do you have "Show Hidden Devices" under view turned on? I had to ask, because I cant see

  • @Psycogeek Just did that and all that appeared was multiple WAN Miniports, one of which was IPv6. Nothing else.

  • @Aaron - Sure you do 20-16-D8-3D-34-3D that isn't a IPv4 address. Most service providers currently assign both a IPv4 and IPv6 address to their customers.

6to4 only works when your system has a public IPv4 address. As you have private address 10.200.112.3 it is not possible to run 6to4 on this system.

6to4 is also very unreliable, so I advise you to avoid it. If you want IPv6 access you are much better off looking at reliable tunnel brokers like Hurricane Electric and SixXS.

  • HE's Tunnelbroker is what I'm trying to use. I think I'm supposed to use 6to4 to connect, but I couldn't find many guides out there, so I could be wrong.

  • No, you use a v6v4tunnel adapter for that. If you go to your tunnelbroker.net account look at the "Example Configurations" tab. You'll still need a public IPv4 address though (unless you can make your firewall forward protocol-41 packets to an internal PC)

  • 6to4 works fine for me (UPC Poland) Might depend on the ISP, though.

  • 6to4 depends on both the outbound relay (for traffic you send to the IPv6 internet) and the inbound relay (the traffic from the IPv6 internet to you). If 6to4 works for you then at least you (currently) have a good outbound relay. The inbound relay however depends on who you are talking to. If you talk to Google you will get traffic through the inbound relay that is closest to Google, etc. So 6to4 always remains unpredictable. Note that modern operating systems avoid 6to4 if they can and have a fast fallback to IPv4, so you might not even use it that much or notice its problems...
