The Next Net
Qa32 wrote to give a heads up on a BBC article discussing the IETF's plans for the future, including information on VoIP, IPv6, and security concerns. From the article: "Given the net was designed for the whole community, it has done well to reach millions. If you want to reach the whole population, you have to make sure it can scale up."
From part-way down TFA:
Interesting for many here that the new guy at the head of the IETF seems to give this issue such emphasis.
If you disagree, post your argument. (-1, Overrated) isn't your personal censorship tool for views you don't like.
This history of IPv6 will never be introduced on our planet when the big players (ISP, Datacenters) and universities start using our their network. Someday I asked my Internet provider when will they start using IPv6 on dial-up networks, imagine what response did I got? "IPv6??? What is it"

"If you want to reach the whole population, you have to make sure it can scale up."
I thought with the current schema the internet uses it was allways setup to scale and allow for redundency, where one section can do down and a new one can take place. Or new networks could easily be added, and expanded off of.
Even new technologys like P2P and torrent etc were able to come out, still functioning correctly with the internet with no changes.
Maybe they mean the ability for the technology to scale up, meaning situations like the IPv6 would not be such a consern. But then again IPv6 is a huge change to the entire structure of how the internet functions.

This is not an all or nothing thing. We do not have to turn out the lights on IPv4 before we can start utilizing IPv6.
How about replacing http into a stateful protocal?
True, IPv4 addresses are a subset of the IPv6 address space.
However, if the site in question does not support IPv6 packet formats, then an IPv6-only host would not be able to contact the site, as the site would not be able to form the IPv6 packets back to the requesting host.
So either the requesting host would have to have an IPv4 address available to it (either directly or via NAT), or the requesting host would be unable to access the site.
And the simplest way a web site can advertise its ability to support IPv6 is to have a AAAA record in DNS.

Whatever happened to Internet2? Was it just another Bubble scam, in reverse? Just a way for academics to rip off government and investors with handwaving promises of "Next Generation" apps, from the magic cloud that birthed the first Internet (but without the genius and visionaries)? Internet2 has been in "startup" phase for almost a decade - where's the return? And if it's just percolating beneath the surface of these announcements, why isn't my taxpayer investment getting the credit? For starters, where's the massively scalable multicast infrastucture that would enable all these hypermultimedia apps that everyone wants?

Problem 8. (IPv6) (a) Given that IPv6 addresses are 128 bits, calculate the total number of possible IPv6 addresses. (b) Calculate the surface area of the earth in square feet. Consider the radius of the earth as 3,963 miles, and one mile is 5280 feet (the surface area is 4ðr2). (c) Calculate the number of IPv6 addresses per square foot of earth surface. (d) Repeat the same calculations for IPv4; how many IPv4 addresses per square foot?(a) 2128= 3.4 x 1038number of IPv6 addresses. (b) The surface area of the earth is 4ðr2where the radius r = 3,963 miles. The surface area turns out to be 1.97 x 108square miles = 5.5 x 10152 square feet. (c) There would be 3.4 x 1038/5.5 x 1015= 6.2 x 1022IPv6 addresses per square foot of earth surface. (d) 232= 4.3 x 109number of IPv4 addresses. Divided by the surface area of the earth, there would be 4.3 x 109/5.5 x 1015= 7.8 x 10-7IPv4 addresses per square foot.3
slashdot: where everyone yells sarcastic metaphors to themselves to understand the issue
From what I can see, what's held up IPv6 adoption is the NAT router, and IPTables/Netfilter in particular. These IPTables guys have managed to come up with hacks for many of the difficult protocols, so that even cranky beasts like MSN Messenger are fully functional. NAT has its problems, of course, and at some point we're going to have to dump IP4, but I think it's longer off then some hope.
The world's burning. Moped Jesus spotted on I50. Details at 11.
Verizon just laid fiber in my neighborhood (suburban Pennsylvania) and are rolling out 15mbps for $40/month. Not bad.
According to my calculations, IPv6 allows us:
Over 300 million IP addresses per cubic millimeter of the Earth.
One IP address for every 5 cubic meters of the entire solar system within the sphere defined by the aphelion of the orbit of Pluto.
180,000 IP addresses per cubic light year for the estimated size of the entire universe.
Yup, I think we have enough.
Make me a friend and I'll mod you up
NAT is the ISPs way of keeping its subscribers in line, and acting as consumers rather than citizens. Given the TOS of my ISP, it just doesn't matter whether I get NATted, or not. Anything I could do that I can't do behind NAT isn't allowed.
The living have better things to do than to continue hating the dead.
"That clearly is not enough when you have 10 billion people to serve, so there is technical solution, the new version of IP - IPv6."
Where did the other 3.5 billion people come from?
