U.S. DoD Commits To IPv6

babaloo writes "According to this article the U.S. Defense Department wants to move it's entire network to IPv6 by the year 2008. Will this be what pushes at least U.S. based companies and providers to actually convert over?" It's definitely a shot in the arm that IPv6 needs. This seemed to be more of a priority back when NAT was much less prevalent, but it seems we'll eventually find ourselves on IPv6, even if we drag our feet there.

      (I'll flip the coin and decide you're not trolling, because there _is_ something generally useful to say here...)

      It isn't actually that every computer has one IP address - it's really that every _network_interface_ has one IP address, but if you've only got one network card that's close enough to the same thing. The IP address has two parts, a network part for the network you're connected to and a host part for your machine itself. On the current IPv4 the address is 32 bits, which was plenty back in 1980 but is looking a bit tight now, while the newer IPv6 stuff that almost nobody uses yet has 128 bits, which really _is_ enough for everybody. The actual storage it takes up isn't very big - the 8 bytes of IP address is a lot smaller than the 4KB of email message you were sending or the 64KB JPG or 4MB MP3 you're downloading.

      So your computer knows its IP address, and the space of IP addresses for the local network it's on, and usually the IP address of a router or other host that's smart enough to figure out how to route packets to the rest of the world. There's a protocol called DHCP (Dynamic Host Configuration Protocol) that lets machines that don't know their IP addresses broadcast a request for somebody to tell them who and where they are. There are simple routing protocols like ARP for finding the ethernet addresses of other machines on your LAN, so your machine can talk to the local machines, and a wide range of routing protocols for finding how to get packets to the rest of the world and how to tell the rest of the world that you're there. Usually, though certainly not always, an end-user computer or a server machine isn't running the routing protocols itself - it usually has the address of a router, and sends any traffic that's not for local machines out over to the router to take care of.

      A router might or might not have to run routing protocols. In a typical home or small business, there's just one LAN connection and one WAN connection, and any traffic that's not local gets sent out the WAN connection to the ISP. But if you've got more than one connection (e.g. if you're an ISP), then you need to know about the topology of the outside world. Usually this is done with BGP, and what really matters isn't so much how big the addresses are that a router keeping track of, but how many ranges of addresses it's keeping track of, e.g. how many ISPs or big businesses it knows how to get to, and how many outgoing connections it has to get there on.

      IPv6 was supposed to do lots more than give us bigger addresses and make IPSEC-like security standard. One of the things it was supposed to do was provide better ways to aggregate information about networks and connectivity to make routing protocols easier to use. I'm not convinced that it really succeeded.

    Solaris has had IPv6 for several years, and the current release its on by default, plug it into a network with an IPv6 router and it works. M$ is playing catch up by including it natively in XP, but it still takes some tweaking. The linux distros will have to start making it enabled by default (no more kernel recompiles), but that may be happening as I type this. More and more applications are being written as fully IPv6 aware, and most of the traditional apps like ping, FTP, traceroute and SSH are now re-written to use IPv6 when a AAAA record is returned from a DNS lookup. There still is a lot of work to be done, like fully working dynamic DNS updates, and DHCPng, route servers, and a free (as in everything) certificate system for IPSec. Every new release of every browser should check for IPv6 and use it whenever possible, M$ claims that will happen starting with their next desktop releases.

    Where I've seen the most far-sighted development is in the newest generation of GSM mobile phones. All the big players are including IPv6 in their current handset designs, and the carriers are now developing value added services to sell. So its not just each phone is individually addressable, but can roam onto competing carriers networks and still have a globally accessible address. Internally, every carrier in Europe with 2.5G/3G services is running IPv6 for everything (except for a few dinosaurs about to be extinct). The other big area is giving each credit card with a smart chip (anti-fraud and verification chip) a range of IPv6 addresses. When the card is put into a reader or used for an online purchase, the chip will actively participate in the verification step by being uniquely addressable and requesting end-to-end encryption. There were several card manufacturers showing off their tiny IPv6 stacks at a recent smartcard trade show.

    As I've pointed out in a post months ago, many ISPs here in Europe are making IPv6 available for early adopters, in the hopes of riding the next wave to some higher margins. I've had clients ask me for advice on getting onto the "new internet", because they didn't want to get left behind on the "old and obsolete internet". Then I point out how they are already on it, and my installations use the "new internet" whenever possible.

And then I said, "Yeah but Francine, doesn't this like, ever become a problem in knowing exactly how much to use?" and she shrugged her shoulders and nodded!

    So that means the European kitchens are less precise than American and English. They just take any old cup, any old spoon! So where is the advantage of being metric?

    The problem here, if you'll take a moment to think about it, is that the authors of these cookbooks are not using the metric system. If they were, the problem would disappear. (In fact, if they would use any consistent system, the problem would disappear.)

    How the author manages to blame this on the metric system is beyond my comprehension.

    The best part comes next. I think my whole attitude on this "essay" can be focused on this one small quote:

    So we have this friend who is a carpenter, and I see him, and I say, "Hey, Freddie, when you have a board a meter long, how do you divide it into 3?" And he sortof gives me a funny look, and says why would he want to do that. And I say, well, How does that work? Because in the metric system, a third of a meter isn't marked on your ruler so what do you do? don't you ever have a board of one meter that you have to divide by three? And he says No.

    You don't need to read anything else in this essay---even the rest of this paragraph, where he goes on to say that people buy wood in 120cm lengths---because it's all here. Nobody cares if you can't divide a metre into 3, just like nobody cares if you can'

I'm sure the guy's just pointing out reasons why metric isn't as logical as many of the eurosheep think it is. And trust me, there ARE such reasons.
      You don't need to read it. I quoted the relevant parts.

      And a metric cup is 250ml, so you can still ask for a cup of coffee and get what you're expecting.

      Metric has no basis in reality. Inches are about the distance from the tip to the first knuckle of an adult human's thumb, give or take.
      So what? A metre is 1/10000 the distance from the equator to the pole, give or take. Who cares? For that matter, a metre is the distance from your hips to your heels, give or take. Does it matter?
      ...if you don't have a measuring tool, with metric measurements, you can't make one easily. That was the guy's point.
      No, the guy's point was that you can't accurately divide a ruler into fifths. He was wrong.
      Scientists are probably better off using metric, but not Joe carpenter building your house. You'd probably rather have your house fit human measurements, rather than be correct to metric measurements.
      Actually, I'd prefer my carpenter to use a ruler, rather than his thumb or his foot, thank you very much.
      And another fact, numerically: a foot can be divided into inches without fractional or irrational result by 1, 2, 3, 4, 5, and 6.
      Nope. You can't do 5. Besides, again I say, who cares? Who ever needs to do this?
      Beyond that, a foot can be divided into fractional, but not irrational, inches with 8, 9, and 10. Only 7 and 11 give unwieldy numbers. Again, decimeters aren't as flexible.
      Wrong again. No fraction produces an irrational result, so decimetres are equally "flexible" by this criterion.
      So keep doing your simple geometry and using your metric system. Just don't force it down our throats.
      I never said you should use it. I only said the arguments against it are bogus.

Centimeters don't really have an equally easy application for people with no rulers. I'm not talking about building a house, for which I would not want "thumbs, cubits, and feet (w/ toes)," but I don't care what measurement system it is in, as long as it is consitent.

      I will add, however, that despite the fact that I am an American, I think the U.S. is too stubborn on its use of imperial measurements. I'm not trying to make any political statements with this, but if "because I said so" or "because that's the way it is" is a valid argument (which, for most bosses, it is), then "because the rest of the world uses it" would seem to be a much better one. Especially if we are trying to work together to advance the world as a whole.

    Both the cable companies and the telcos are ISPs. One of the reasons the cable companies are against it is that thier business model (and as a result their network architecture) is predicated on a per machine fee; NAT gets around this. When too many people get on the local loop (and that loop is quite large) their network sux hind tit.
