Comcast and CenturyLink are the only two viable players in my area and neither provide native IPv6 addressing (even though I've requested it from my current provider comcast many times). So I'm still forced to use the he.net tunnel that I setup 15 years ago or so when they first started offering them (after 6bone closed up shop because testing was through), and even with this, I'm forced to disable auto provisioning of IPv6 addresses because various problems with access to IPv6 web pages / services, etc.. With auto provisioning enabled, the wife was constantly complaining about her facebook and instragram apps not connecting (which is no surprise since these services advertise IPv6 addresses and yet have a horrible fucking track record when it comes to reliable connectivity.
Anyways, the problem with IPv6 isn't the address space, it's the lack of stable services within the address space, and the on going failure of major ISP's to roll out addresses.
