AT&T: We're Doing Just Fine on IPv6 Transition
Company Says 5 Million Homes IPv6 Ready By End of 2012
While companies like Comcast have been aggressive in getting IPv6 deployed, AT&T has been somewhat quiet on the matter. That was until recently, when the company hinted that their IPv6 plans involve deploying carrier grad NAT
as an IPv6 migration attempt. U-Verse users were recently told that as AT&T deploys carrier grade NAT, they'll need to change their subnet and pony up $15 a month for a public IP address to keep everything working correctly.
Perhaps noting Comcast's favorable IPv6 press coverage, AT&T CTO John Donavan took to the company's blog
to claim the company will have up to 5 million homes IPv6 enabled by the end of 2012:
One important way we’re making that future possible is by leading in the transition to IPv6, the successor technology to the nearly-exhausted IPv4 standard. Due to the extensive amount of behind-the-scenes work and preparation by AT&T and other key industry players, the transition will be nearly seamless for our customers. AT&T already has nearly one million residential broadband customers who are IPv6-enabled, and that number is growing rapidly. With IPv6 native traffic volumes significantly picking up on our network, we are well-positioned to support a successful World IPv6 Launch today. In fact, we far exceeded the goal for participating service providers to have one percent of residential wireline subscribers IPv6-enabled.
AT&T is using a managed tunneling approach known as 6rd
, an approach Comcast heavily tested and discarded before focusing on their native dual-stacking approach.
so which is it?? Oh AT&T.
...I hope this doesn't affect me.
My "podunk" cable company (can't find jack about these guys - no website, nothing on google) seems to be directly "re-sold" AT&T. If they directly allocate from them, I'm wondering what the chances are that my connection will suddenly be switched over. Suppose the chances might also be just as good for keeping a "real" IP address, but I have no way of knowing.

That if AT&T takes my public IP address, and then will ask $15 to get one back, that will be the day I will call Time Warner Cable.

6RD problem - very few consumer routers support it If AT&T makes 6RD their method to get IPV6 working on their network, users will end up locked in to only the couple home routers AT&T will support or rent to you as a combined router/gateway. Their users won't be able to use std off the shelf consumer routers.
See If I was an AT&T customer and this is what I was told, is that they are ready but I have to buy static IP to really use the internet the way it's meant to be used, I'd file an FCC complaint, and a BBB complaint, especially if I was a customer under contract, and then I'd cancel services without having to pay an ETF, because I wouldn't pay AT&T a "royalty $15 fee" just to use the internet the way it was/has been designed to be used.
Even when I worked at AT&T and heard of this I never thought it was a great idea, and at the time I knew they were doing this as a way to force users to pay more for the service, the sad part is even though the company says they will eventually transition IPv6 to the way IPv4 is today, I really seriously doubt that, AT&T wants to be the gatekeepers (is anyone here the key master?) and severely raise rates on their products just to please their investors. Oh well, I say let them continue, at this rate they are going to have customers running for the hills in droves a lot faster due to their inability to understand basic customer satisfaction. I just hope if they fail that they don't get bailed out...

6rd === Fail... 6rd is very useful for a test deployment: as a way of getting users connected using IPv6 before your infrastructure is fully up to date. I was one such participant in Comcast's 6rd deployment. It worked, and worked well.
But for a general solution, its a Big Bucket o Fail: It requires new customer-premises equipment to encapsulate the V6 traffic into V4 packets, which are sent to the ISP's server which deencapsulates the traffic.
Yet the only advantage is that it doesn't require the ISP to update the path between the user and the ISP's 6rd gateway. But this cost is low, since most of this hardware has already supported IPv6 for years and if it doesn't, the vendor needs to be browbeat into fixing things.
And 6rd also removes the big advantage of IPv6: IPv6 enables DS-Lite, where the CPE encapsulates IPv4! in IPv6 which is then deencapsulated by the ISP. DS-Lite, unlike carrier-grade-NATs, has much better failure modes, scalability, and similar benefits when the ISP wishes to NAT the IPv4 addresses.

There's ZERO excuse for an ISP (a Teir 1 ISP even!) to not have efficient IPv6 capable hardware *everywhere* in their network
