I'm afraid of the possibility that instead of adopting IPv6, internet providers will just switch to ISP-wide NAT, making the internet even more asymmetric than it already is.

From what I understand (which admittedly is not all that much) implementing so called carrier-grade NAT would be almost as expensive as transitioning to IPv6 would be. And even private ranges are finite, which afaik was one cause for Comcasts applaudably early transition to IPv6

IPv6 is just like the transition to Python 3: it'll happen... eventually. But the only people with an incentive to put the hard work in are people who are genuinely enthusiastic about the transition. Everyone else is sticking it in the too-hard basket.

Earlier quoted context omitted.

To be clear: transitioning to IPv6 is a two step process: 1) you need to enable IPv6 everywhere 2) when that is working, you can sunset IPv4 So, every transition strategy involves both the life support for IPv4 and the delivery of IPv6. Sometimes the ISP has no choice but to use it. And iff the ISP also rolls out IPv6 in parallel, this is fine, the users can access the dualstack websites over IPv6, while still using…

Agreed - ISP wide NAT will be necessary, but if they choose that instead of ISP wide NAT+IPv6, then we're in trouble! EDIT: Also - Everything I have a hand in is accessible via both IPv4 and IPv6..

In my conversations, the vast majority of the folks who are going to have to deploy CGN, also have already running programs to deploy IPv6. It's just that they don't necessarily advertise them, and also that these things take years - the access is by far the hardest part of the internet to transition.

At my $employer, a couple of bright interns this summer made this: http://6lab.cisco.com/stats/ - which aggregates the stats from various places and allows to get a more rounded view. Besides for the access part (EDIT: which, as I said, just takes some time), the situation is not bad at all!

EDIT: And, kudos to dualstacking your gear! :-)

This seems to have been rumbling on for some time now - at least for the past five years or so. My OS supports IPv6, my home router supports IPv6, but at no point have any of the home ISPs I've used (three in the past five years - BT Internet, Be and Origin Broadband) made any mention of any sort of IPv6 support. I'm not au fait with the workings of such huge operations, so is there any reason for ISP adoption of IPv…

Eircom (an Irish ISP) are trialing IPv6 currently, and the routers they have been shipping for the last year or so support it. Other than that, our co-location provider Blacknight offer IPv6 to their customers.. but that's not exactly residential!

BT / Esat were trialling IPv6 as early as 2005 and giving native allocations around that time also

This is a fairly outdated meme by now. Just that the enthusiasts are loud about it. Everyone else does not rush tell the world about their plans - it takes on average about 3 years to get everything in place, so this is a pretty good head-start against the competition :-)

My ISP (Andrews&Arnold, UK) offer IPv6, so I have a /48 and (since I bought a new modem recently) all my machines are now natively IPv6 with no tunnelling involved. (A&A also support tunnelling if your modem/router is IPv4 only.)

Comcast, at least in some parts of the country (e.g. SF's East Bay). You don't even have to ask them. One day I noticed my router was being advertised an IPv6 route. I switched on DHCPv6 and got an IPv6 address, as well as a /64 prefix for the rest of my network.

Unfortunately /64 is all you can get for now, which isn't really sufficient, but they've promised to delegate shorter prefixes in the future.

Not sufficient for what? (Honest question.)

I didn't realise I stumbled upon a meme!

Yep and nothing will be done by ISPs until they are all completely gone (and maybe not even then, scarcity is good for business).

This isn't true. Comcast, Verizon, and T-Mobile are a few of the big eyeball networks who are making large infrastructure investments in IPv6. ISPs are far ahead of most content and hosting providers in this area, as they bear the pain of IPv4 scarcity when providing addresses to their subscribers. Transit providers are on the whole prepared for v6 as well. As an ISP, you don't want to wake up one day and see analysi…

Not only are they making large infrastructure investments, a many of their customers (including myself) can get IPv6 service from all three of those companies today and have been able to for some time.
