> My mobile operator and my ISP at home both provide IPv6 connectivity without me asking. All I had to do was to enable IPv6 on my router.

I think this is representative of every IPv6 deployment. You get it or you don't. If it isn't available to you, asking won't make any difference.

FTR we have 6 wireline ISP here. Cable has IPv6, the 5 fiber operators do not.
