As a small ISP, my question is, what benefit do I get by adding IPv6? I have enough IPv4 addresses for all my clients and although I get the occasional client asking when we'll make IPv6 available, when I ask them why they want it, the answer is mostly something that sounds like "because IPv6"

If that anecdote is true, they're doing something wrong. What I hear is there is no performance impact in general, with some reports of bulk data moving faster with IPv6 (probably due to some kind of MTU issue).

It's slow but steady progress given the enormity of the protocol changes introduced and the lack of backward compatibility.
