Been involved with this. It has been in use for 10 years! Facebook recently turned it on and will be keeping it on moving forwards, as have Google, and many more intend to after this test day.

Unfortunately a lot of our ISPs don't seemingly care, and this will lead to user experience problems in e next year or 2. Virgin Media don't have any plans to offer this, for example.

How will this affect my attempts to watch american videos? (some just need the modified headers, some need hotspot shield)?

those ISPs that arent upgrading (because most the significant ones will have) because alot of the hardware has poor support and its really not that big a deal. NATing and other network wizardry means its not necessary. as far as i can tell legacy IPv4 and IPv6 can coexist for decades, so why bother doing a change now when you can wait for the next round of kit upgrades? IPv6 opens up capacity for individual devices to be accessed directly but who needs that? IPv4 is fine for the number of places needed to be accessed.

If I'm going to start the next Facebook next year, and there are no more free IPv4 addresses left in this world, how are people with no IPv6 going to access me ?

We are so behind with this, Japan's biggest residential ISP offer it, the biggest US ISPs offer it or have a plan to this year (Verizon, AT&T, Comcast)

I'd pretty much guarantee the kit 90% of ISPs use can do it, but the customer routers they give out, stupidly don't support it, mainly because bad engineering choices have been made!

Anyway plenty of other ISPs offer it native, so the choice is there.

why on earth would you need a seperate address for every person on Facebook 2.0? you have URLs which are infinite in their name space. the server farm hosts it all technically needs only a single IP, albeit not clever.

If my Facebook 2.0 is on IPv6 only, since IPv4 has nearly run out (and will do within 12 months) how do IPv4 only customers access me ?

same as any current web server, through virtual hosts, NATing and all the other networking voodoo. this is why no one is really much bothered about IPv4 "running out" of addresses, theres not any impact to general usage. it just means you wouldnt be able to allocate a globaly unique IP address to your fridge, but then why would you want to and why wouldnt you put this behind a local network.

Where am I going to get these IPv4 addresses from?

Either way, all this hackery and bodges, just because SOME ISP's don't have IPv6 on their technical road maps are silly. If the majority of ISPs have an IPv6 stratergy, I'd bet these will be successful in the coming years. Also can you imagine many of the home users these days, trying to play on their xbox or ps3, and using double NAT or similar with success?

from the ISP as you do now. the address range are not remotly exhuasted as claimed. my company recently came to be assigned 2 class C ranges because the ISP couldn't be bothered with the admin of reassigning us to a new range small enough for the half dozen needed. so thats 500 IPs allocated but unused.

The burning question I have about all this gobbledegook is......will it affect my ability to find porn on the interweb ?

no. and when its likly to affect that, then ou can be sure there will be wide compliance.

You're missing my point. What happens when IPv4 has run out? And why would any large company hosting something like Facebook v2, want to be tied to an ISP with IP Address space that cannot be moved? Seems so many people are thinking of ways not to move to IPv6, probably because they don't understand it, rather than embracing it. I hope all my competitors have attitudes like yours :)
