It's surprising to that all comments (except a few) state that IPv6 is not hard. I'm not an IPv6 expert but I did spend time learning it (may be even more than I spent on IPv4 but with v4 I have more practical experience). I used v6 for a few years at home / home lab (and for a side project). I think IPv6 is hard - there is much more one needs to know to use it well than in case of v4. Any deviation from a happy path (a non-standard configuration / use case) is a pain (or at least it was 10 years ago, don't think it is much better now except now we likely have even more RFC to learn). Not used IPv6 recently so cannot name specific problems but I didn't enjoy working with it at all. Will do it again only if it will be well compensated.

I think there's a big difference between enterprise IT folks who can specify hardware with good IPv6 support, and which are able to switch internet providers if they don't support IPv6 well. It's entirely a different thing for home users which get handed some shitty router from the only ISP around. My options are cable or long-distance ADSL. The cable ISP has dynamic prefix, so I get a new prefix every week or so. If you contact them regarding IPv6 there's zero support, I had to find the prefix length by trial and error. So much software relies on the prefix being fixed, so this can lead to a lot of frustration. On the bright side I actually get a prefix, some just get a /64. IPv6 might not be hard, but using IPv6 might indeed be hard.

    I can use SLAAC, which is nice for non-server hosts like our Android phones and such. And AFAIK privacy extensions rely on SLAAC.
