How to access IPv6 websites via the mobile network
You can only reach IPv6 sites from your device if it has IPv6 connectivity, whether it be via an IPv6-enabled WiFi network or via your mobile carrier's network. It is not generally possible to reach IPv6 sites if you only have IPv4 connectivity.

The below is no longer relevant because SixXS is now defunct. Thanks to Rodney for the tip-off.

You can set up an IPv6 tunnel for the times when you are on a network that doesn't provide native IPv6. I was able to find two Android apps which set up tunnels to the free SixXS network:


The Androiccu app is based on the aiccu program for PCs that sets up SixXS tunnels. It claims to require a rooted phone.
IPv6Droid claims to be able to do the same, without requiring the phone to be rooted.


I've used SixXS and aiccu since 2006 and they are generally quite good, though their points of presence can go offline or be decommissioned without notice.

I haven't tested either app, as I've had native IPv6 at home for a few months and on my mobile for a couple of years now. Given that I know in general how tunnels are set up, I would expect the app requiring a rooted device to be more reliable, and if you are rooted, I would start with that one.
