I think it pretty likely that once we reach 50% it will switch from "That thing that techies care about" to "Something people assume everyone has", and that any remaining ISPs that don't provide IPv6 will rush to get it done. I'm sure that IPv4 support will continue for a fair while though.

What's the mechanism that makes that first company drop support for IPv4? Cost? It feels like it'd need to be a dramatic cost saving in order to kick in at 50% adoption.

See the graph here: http://www.potaroo.net/tools/ipv4/index.html

ARIN is going to run entirely out of IPv4 addresses for general distribution in April of 2015.

It's not going to be long before you'll need IPv6 if you want to do anything peer-to-peer.

My ISP here in SF, Webpass, has begun deploying their customers behind an IPv4 NAT with an IPv6 /64 prefix. I think this trend is going to be more common with consumer ISPs. I mind a little bit, since VPN access is impossible on IPv4, but with mobile carriers deploying IPv6 I think I will care less as time goes on.

It is noticeably faster to use IPv6 with Google, something like 4ms vs. 30ms connection times. I'm not sure if it's a more efficient route, or underutilized routers handling the traffic.

I hope everyone is aware that IPv6 is the perfect way to bypass rate-limiting for systems that analyse Google results (for SEO ea.) There's a good chance a lot of this traffic consists of those bots testing Google's results ....

I've noticed similar stats on my own IPv6 enabled sites. Last year a non-tech conference I worked on the registration system for had a similar fraction (of the non-spam paying registrants) signing up via v6.

ISPs are already dropping support for "real" IPv4 and only offering NAT. At the other end, there are already cloud providers that charge extra for an IPv4 address on your server.

A couple of years ago my ISP dropped their usenet servers - not enough people were using them to justify the cost/maintenance effort. I expect we'll eventually see the same thing with IPv4; not for ten or twenty years perhaps, but once "everything" is using IPv6, it becomes a cost center.

I imagine people will start deploying multiple HTTPS sites on a single IPv4 address but with individual IPv6 addresses. People still using only IPv4 on Windows XP with Internet Explorer will not be able to access those sites (no SNI), but they will soon be a tiny minority.

Two comments about the presentation itself: 1. The color selections on the "Per-country IPv6 Adoption" tab are abysmal for those of us with poor color perception. 2. Since we're talking about replacing outdated technology, why use a Flash-based graph on the "IPv6 Adoption" tab?

The graphic in the "Per-Country IPv6 adoption" tab appears to be implemented with scalable vector graphics.

Or when I look at the company I work for it's just that nobody bothers because not having IPv6 hasn't caused a single problem so far.

At work (a larger enterprise in Europe) we already see quite a bit of pain with IPv4. B2B connections are increasingly not using globally unique addressing anymore, so we often need to use prefix NAT and application level proxies to bridge clashing address space. This in turn is a support nightmare and is hurting reliability. Our network guys seems to love the extra complexity, though.

I hate VPN-ing into other people's networks, it is such a pain-point. As you say, you have address/space clashes, and all kinds of other (sometimes even security) problems.

It sounds easier than it is, the main issue is scaling. Need to connect to one other person for B2B? Trivial. Two? A little harder. Ten, twenty, fifty, ouch...
