We are between step 2 and 3. Looks like a /22 is $500 currently: https://www.arin.net/fees/fee_schedule.html.

Hmm. I would argue that we're still in step -1, though the clean shaven folks have finally started listening to the neckbeards in a few circumstances and are slowly moving around towards step 0.

Most people still can't actually route IPv6 over their tubes without going through a tunnel broker. At least for home, small office, and companies that aren't tech heavy, it's still firmly in the neckbeard camp.

Well, you definitely can route IPv6 over the public backbone. If you get an IPv6 address in SF and I get one in NYC, we can already talk to each other. That is how we got past step -1. Dual stack is now a pretty standard setup on a non-trivial, though still small number of networks. For example, Linode, Comcast, T-Mobile all support dual stack on at least some of their networks.

What we have not quite reached yet is the point where IPv4 addresses are really expensive. You still get one with every VPS you sign up for and with every home connection. Once that can no longer be done, IPv6 will become standard pretty much across the board, starting in Step 3 and 4.

As another example, when I am using LTE on Verizon Wireless, I am connecting over IPv6 to sites running IPv6 (ex. Google, Facebook, Wikipedia, etc.). I can go to sites like http://www.test-ipv6.com/ and see that I have full IPv6 connectivity.

Hey, so I had posted the above primarily because I've been trying to get a routable IPv6 address for a while, and haven't been successful; I've repeatedly asked Comcast when my CMTS would be IPv6 enabled, but their techs have just said "try enabling IPv6 on your computer and see if it works", they haven't been able to give me a schedule or even tell me if it was supposed to work yet.

However, just checked last night and discovered that they'd added a new feature that would tell you when your CMTS was IPv6 ready, and it turns out that they've finally upgraded me. I could finally switch off my tunnel and use a real, routable address. Woo!

Major (consumer) ISPs in Australia offer native dual-stack.

Which ones? I'm with iiNet and was wondering if they offered it yet but couldn't see anything about it online.

Yeah, but thats only for those who meet the requirements. The Real world scenario is that people pay about $500/mo for a /24 I heard - kind of a black market thing.
