IPv6 is Here 420
shawn(at)fsu writes "Reuters is running a story that Vinton Cerf of the Internet Corp. for Assigned Names and Numbers (ICANN) says that "IPv6 been added to its root server systems" I like how they said that it will run along side IPv4 for 20 years to get rid of the bugs.

Cerf said about two-thirds of the 4.3 billion Internet addresses currently available were used up, adding that IPv6 could magnify capacity by some "25,000 trillion trillion times."
Of course, if v4 runs along side of v6 for 20 years that may mean that it would be harder to implement an IP-per-user scheme. I don't know. But, 20 years should be enough time to work out any bugs:
He said the IPv6 system would run parallel to IPv4 for about 20 years to ensure that any bugs or system errors were weeded out.

That's because everyone in the network can establish a connection to them, while a NATed node has only the connections it establishes itself (to clients that aren't NATed).

Having more IP addresses doesn't mean that they will be statically assigned, nor that they will be assigned on a "per-user" rather than on a "per-device" basis. Even if each individual were assigned a block of addresses for their devices (this packet comes from John's palm pilot, this from his cell phone, and that one from his refrigerator...) you'd still have the problem of multiple users with a single physical device (public library computers, internet cafes, office beer fridges...) so, unless each device includes biometric identification and logging, you'll never be able to attribute every internet communication to a human party, even when one exists. I won't even get into the privacy concerns there.
The vast majority of bad netizenship occurs at protocol levels above IP -- spammers abuse SMTP, advertisers abuse DHTML, hackers abuse various services running on open ports.

At best, you'd continue to have a dynamic address, and then have a static address that resolves to some sort of forwarding service. So some agency would own a big chunk of 6 billion addresses (and routers would only then need that one routing entry), and then that agency's network would reroute packets to those addresses to your current dynamic IP assigned by your ISP for whichever device you want the IP to relate to.
Which is pretty pointless and stupid, because you'll have many different devices and thus many different IP addresses, so what purpose would there be in having a single static IP just to refer to you personally?
