Re: Welcome to the club
The bigger question is: Why do still almost all websites and internet services support only IPv4, and why do most ISP's still not offer proper IPv6 support?
Running out of space apparently means NOTHING to these hosting outfits and ISP's. Nothing at all. Because they still don't offer even the simplest IPv6 accessibility. And they've been warned for years.
Now, I'm with a hosting firm that offers IPv6 IP's on even their basic £10/month account if you want one. You click a request button and, bam, it gives you an address. Trouble is that it does exactly that for IPv4 as well and you can get 5 consecutive addresses, no questions asked. The fact that they're consecutive tells me that they actually allocate 5 to each customer anyway.
It honestly and truly looks like people won't give a damn (even the techy people, who are supposed to be leading the way and reading things like The Reg and Slashdot, neither of which offer AAAA records!) until they can't get an address. Especially when the doomsayers have been saying for years that we are running out, they're just not going to listen until there's none left and then they'll face some awkward questions like "Why can't we buy a website that's accessible to 99% of our customers who only use IPv4 still because that's all their ISP/router offers them?".
And for all the scaremongering, those leading the charge and reporting the shortages are the worst example: bbc.co.uk, theregister.co.uk, slashdot.org, etc. do not have AAAA records and even google's IPv6 requires your ISP to be "approved" by them for compatibility before they open it up to you. Is it hard to publish an AAAA record for a website? Not really. Certainly nothing compared to deploying a script of some kind. But nobody does it.
Sort it out, websites and other Internet services, and then maybe we can all be high-and-mighty about the end of IPv4 rather than sheepishly reporting it and hoping it doesn't happen.
