MIT Technology Review Slams IPv6

PCM2 writes "In the MIT Technology Review, Simson Garfinkel, noted author of Internet security books, writes that "the next version of the Internet Protocol, IPv6, will supply the world with addresses by the trillions. Too bad it will also make the Net slower and less secure." His article goes on to explain that all IPv6 code is untested and therefore insecure; that IPv6 makes encourages 'peer-to-peer based copyright violation systems'; and of course, that the switch is never going to happen anyway (and yet, somehow, the United States is 'falling behind')."

      Why will people gradually switch? What's the incentive? Why should I switch? All my computers speak IPv4. Some speak IPv6. What's my incentive to use IPv6 at all?
      My incentive FWIW is that I have more than one computer in my home and it helps configuring things immensely if I don't have to worry about port issues - if I want ftp or web servers on two of them, NAT currently makes that a pain. As IPv4 and IPv6 run in parallel, running IPv6 loses me nothing but it opens up an easy solution for that particular issue. Not everyone runs these kinds of things, obviously, but OTOH the notion that two gamers might both run servers, or even two people might want to use VoIP applications, is hardly perverse.

      The motive will be that IPv4 will be increasingly a second-class citizen in a world where IPv6 co-exists.

      My ISP only speaks IPv4, because all their customers support IPv4, but only a few support IPv6.
      Mine neither. So I'm planning to use the well documented 6to4 system which allows anyone with a routable IPv4 address, preferably static, to start IPv6ing.
      All the useful web sites are reachable via IPv4. Shutting off IPv4 is suicide for any company. (And please don't tell me about how IPv4 is reachable via IPv6. That kinda defeats the purposes of the changeover.)
      You don't need to shut-off IPv4 when migrating to IPv6. Indeed, 6on4 which you diss as "defeating the purposes" demonstrates that fact by its very existance. We're not going to have a sudden changeover, one protocol is going to be phased in as another is phased out. Even now, I suspect a sizable chunk of people could be migrated to IPv6 right away: simple Web and email users can do so for example as everything they need to do can be accessed via proxies and servers provided by the ISP.
      The mistake is that IPv6 is not an extension of IPv4, just a complete replacement. Therefore, no way to have them "at the same time" (again, I don't mean gatewaying or tunnelling, I mean complete compatbility). Therefore, expensive to switch. No incentive to switch.
      Absolute hogwash. While IPv6 is not an extention of IPv4, it is specifically designed to co-exist with IPv4. You can assign both IPv4 and IPv6 addresses to your interfaces in all the implementations I've seen, and routing is done on the basis of the IP address you use (use an IPv4 address, and your connection will be via the IPv4 network, use an IPv6 address, and your connection will be via the IPv6 network.)

    Those aren't the article's words. In the actual article, only one paragraph out of 3 pages mentions copyright, and it's fairly neutral.

    These problems go away when every computer on the Internet really does have its own IP address--something that's impossible today with IPv4, but which is the raison d'etre for IPv6. In a world with IPv6 and without NAT, every computer in my house has its own unique IP address on the public Internet. That means my desktop can open up a peer-to-peer connection with my desktop at work, but it also means that my daughter can network her machine directly with some teenybopper P2P network in San Jose. Getting everybody's home machine out from being a NAT box should make possible a lot of interesting applications that are either very difficult or downright impossible today. And in all likelihood, some of those applications will not be popular with the Recording Industry Association of America or the Motion Picture Association of America, both of which have taken the lead against peer-to-peer networks. As soon as they understand what a threat IPv6 is to their police actions, they are likely to start fighting against.

    IP layer stuff (OSI model layer 3) is transparent to the layers both above and below it; you can easily map IPv4 addresses (as well as DNS entries) onto IPv6 addresses as long as you have a protocol stack capable of parsing the IPv6 stuff. Nothing new.

    Remember people, IPv6 has been around in RFC form since December 1998 (5 years) - the adoption rate simply hasn't matched what was seemingly necessary.

    Besides, ARIN isn't even close to full address depletion. There's so many spare /8's out there, that I imagine we could go on for at least another 3 before widescale implementation.

    They even made it simple! If my IPV4 address is 203.131.45.99 my IPV6 address will be 0:0:0:0:0:0:203.131.45.99 (there's even an abbreviated notation for a V6 address which would just be ::203.131.45.99)

  16. Re:NAT is bad? by anthonyrcalgary · · Score: 4, Informative

    The problem with NAT is that it breaks some protocols, eg FTP. The protocol says something like "My IP address is X, make a connection back to me.", but with NAT the computer reports its IP as something that's not a valid public address. That not only breaks some protocols, but you can use that to tunnel in past a firewall onto a private network in some cases.

    The other problem is more aesthetic than anything... but it can be a problem if the NAT device is badly configured. Because it has to translate incoming and outgoing packets, the NAT device must track the state of the incoming and outgoing connections. This takes memory, and sometimes there's not really any way for the NAT device to tell when the connection has been severed. So it has to time them out, and this can result in connections evaporating without warning when the server and the client want them to stay open.

    Fortunately, you can usually set this to something more reasonable with OpenBSD or Linux (or another BSD, Solaris, whatever). OpenBSD 3.4 with "set optimization conservative" waits 5 days. I've never had any problems with that, but it's tweakable if necessary.
