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.

Perfect for colonization of other planets. If each human being has their own IP, then we would need to pack a whole bunch of planets to require more than that! They aren't kidding when they say they'll run IPv4 with IPv6 for twenty years. In that time, we won't have used even a fraction of a couple percent of available IPs, even if we assign every human being on the planet with one, and every company with a giant block.

Binding IP's to humans is arbitrary - it's more realistic to expect that every human with money is going to have several IP addresses (appliances, toasters, whatever), while most of the people in the world will have none.
Also, for some reason, I don't really like the idea of persistent per-human IP addresses. The idea has an Orwellian feel to it.

Basic idea - include IPv6 over IPv4 tunneling software in Linksys routers. This would allow people to run IPv6 networks in their houses and talk to IPv6 networks elsewhere. This would fix a lot of problems that NAT introduces, and would sidestep the wait for IPv6 ISPs. It would also provide enough of a user base to encourage application developers to include IPv6 support.
Of course, this would kill Linksys' NAT router sales, so they have no incentive to do so, but I like to think it's a good idea.

Um. IPv6 is big enough to give a Class A subnet to every living person on the planet.
It's big enough to route an entire IPv4 numberspace to every living person on the planet, and to each of their pets, favorite invisible friends, and pieces of furniture.
2^128 is a big, big number.
The point is, they'll be able to "waste" huge swaths of the that numberspace as they build the routing hierarchy, making the network more scalable.

If every IP device gets its own address, but you want to send or receive something anonymously, use a public terminal.
For both snail mail and IP traffic, neither solution is convenient. However, the fact remains that it is still possible.

Of course, since public companies are focused on short term sales they might see the IPv6 tunnel sales increase as worth cannibalizing IPv4 NAT router sales.

A prerequisite for the rollout of IPv6 must be law enforcement getting off their asses and demonstrating that spammers will get busted for their illegal activities. Otherwise it will take 20+ years to ID and block IPv6 rogue IP space.

so lets get with the problem and stop using useless junk like ipv6, and start using something that works, seemlessly, like ipv8.

Right now.. really the only people that can use v6 are the BSD/Linux folks, as well as (I think) OSX. That's like 5% of the entire Internet desktop users, according to Google's Zeitgeist.
It's a scary thought.. but really, I think critical-mass v6 adoption rests solely on the shoulders of Microsoft at this point. We had better pray that Longhorn comes with it enabled (and that's like 2-3 years from now, at the earliest). If that happens though, it's a sure bet that Linksys et al. as well as lots of ISPs will be on board. I think we'll be waiting a while yet myself, though.

Easily solved. How about something like this:
Now at that point, you have a regional host in your original home region which says "the last time I heard from myHostID, it was coming from mycurrentisp.com's routing space."
Next, you ask mycurrentisp for the current IP number for myHostID. It does the same multi-tier lookup based on some division of the 48 bit host id part and hands you back the current IP number with a new top 40 bits glued on. Routing then occurs using only the top 40 bits. This still gives you 256 times the current total IPv4 namespace to use for routing, and unlike IPv4, it can be allocated dynamically.
Now from your server's side, your machine thinks it has a static IP. The first router it encounters speaks some IPv6 routing protocol and says "I'm suddenly seeing packets from a device whose number provider ID is (insert 40 bits here). I'll notify my upstream, which eventually would get to your ISP's name server, which would propagate it across to the number provider's name server.
In a scheme like that, you could have a static IP and not have a static IP at the same time. :-) Or maybe I'm just nuts. Hard to say.

It will depend on whether the ISP's router is sufficiently stateful (and lax about MAC) and/or willing to do broadcasts.
This is were a few quiet conversations between security authorities and the larger router manufacturers (Cisco) can have large impacts. "Our routing/auth tables key off MAC for speed and efficiency. We don't do broadcasts to avoid congestion and security concerns." Plausible deniability.
