June 6 Is World IPv6 Day 2012: This Time For Keeps
An anonymous reader writes "On 8 June 2011 many companies (big and small) enabled IPv6 to their main web sites by published AAAA records; 24 hours later, almost all of them disabled it after the test was done. This year, on June 6th, many of those same companies (Google, Bing, Facebook) will be enabling IPv6 again, but this time there won't be any going back. In addition to content providers, several ISPs are also participating: Comcast, AT&T, XS4ALL, KDDI, and others. CDNs Akamai and Limelight are on board, as well as network equipment manufacturers Cisco and D-Link. Is the chicken-and-egg problem of IPv6 finally, slowly coming to an end?"
There are billions of addresses - entire A blocks - locked up in early-adopter organizations that could be made available.
Given that 2^32=4.3 billion, you're wrong. There are a few million addresses locked up in old class A networks. If you bother to look at the consumption rate you'd realise that even if all of these addresses were returned to the pool they would buy a few weeks and then we'd be right back where we started. In short, recovering those addresses is going to be a lot of effort, will not solve the problem and will only postpone it for a very short length of time.
We're years away from ipv4 exhaustion.
IANA ran out of addresses at the start of last year. APNIC also ran out of addresses in the first half of last year. RIPE is going to run out of addresses this summer. We are *not* a significant number of years away from exhaustion. We've got maybe 3 years until there are no more IPv4 addresses left to allocate by any RIR. Reclaiming the legacy blocks to buy a few more weeks doesn't make sense.

ISPs use 10.x addresses to manage their end user devices. Comcast has already exceeded 16 million users. They already have to kludge together a solution just to manage their devices.
Sorry, but your thinking is outdated and shows a lack of understanding of the true infrastructure of the Internet as a whole. As you have already been told, there are parts of the world today who turn on their devices and don't get a public IPv4 address. Not to mention, this entire article is about key services and websites turning on IPv6 in recognition of the future.
I'm guessing you never lived in a flat Internet. I have. This bullshit we've had to suffer with for a couple decades is actually pretty horrible. When we return to a flat internet, we will be able to video conference from one PC directly to another, anywhere in the world.
It's the future, and in a sense, returning to the past.
