IPv6 Tested in Space

An anonymous reader writes "Remember the Cisco router orbiting on a satellite in space? Well, it's now also the first to run IPv6 in space. Since no-one is choosing to run IPv6 on the ground, isn't this a bit pointless?"

    This is nothing new. The ill fated STS-107 carried a complete CANDOS pacage offering a wealth of IP protocols. In fact UoSat-12 back in May of 2000 ran an ftp server. The only thing new here is IPV6. IPV4 has been in space for a long time. You an find more about this at our website http://ipinspace.gsfc.nasa.gov/

    Since nobody runs ipv6????? Sad, that so many Americans are clueless. Asia has moved into IPv6 in a big way, esp. China. They are all hoping to get a jump on it before we do. China, Japan, and even South Korea have pushed it like there is no tomorrow.

      sort of - there's a lot more IPv6 there than here, but there are still a whole bunch of thoroughly under-implemented pieces of IPv6 (like, has anyone written an actual implementation of IPv6Sec yet?), and actual traffic rates using native v6 native v6 all the way through are exceptionally low.

      If you go to one of the good latency calculators, you'll see that the delta between IPv6 performance and IPv4 performance is substantial, with IPv6 performance showing as a heck of a lot worse (about twice as poor). Once this isn't the case, then an argument for widespread adoption of v6 will be more effective.

      None of the significant US ISPs support native IPv6 transport across an infrastructure without any IPv4 present at this time.

      No government agency does either.

      Evidence? Try to get OSPFv3 working without an IPv4 router-ID. Try to get encryption (IPv6SEC) working without using IPSEC (over IPv4 transport). Try getting VoIPv6 working, or looking for hardware support for multiple queues for IPv6 packets.

      Networx was just awarded a couple of days ago, and specifies those services which are to be orderable over the next 15 years. It shouldn't be used as evidence of what is supported today.

      My contract with Jeppesen ran out in Sept. Since early Feb, I have been working at Verizon Business. Please look up the players in Networx. I can tell you that very little IPv6 is currently being used. The FEDS are wanting to move to IPv6, but none of the players in Networx currently use it (they have small networks of it, but they are all IPv4 shops). Hopefully, that contract will change things.

      Many governement projects treat IPv6 support as a checkbox, not as something to be actually used. There are big, big, holes in the implementations, and nobody really wants to go first...

      Try to get OSPFv3 working without an IPv4 router-ID

      Router IDs, at least in OSPF (all versions) and BGP, are not IPv4 addresses. They are a 32 bit number, that in some implementations are displayed as dotted quad. It is only common practice to make your publicly available router ID to match one of your assigned IPv4 addresses, so that collisions between Router IDs will rarely happen.

      I still run across companies that have router IDs of 1, 2, 3 etc. Some router implementations will randomly grab the lowest IP address of all the local interfaces, and use that if an ID isn't explicitly specified. I've seen BGP4 Router IDs of 10.0.0.1, which switch to other random addresses from time to time, creating all kinds of confusion. I guess it all depends on how well you learned your networking, some training companies are worse than others, and many universities don't bother hiring professors with a clue, and for many cisco==networking.

      This is a straw man argument, close to trolling. Nobody expects an ISP to roll out an all IPv6 network any time soon, but any ISP that expects to continue growing after 2010 will certainly need to dual stack their whole network from end to end.

      I have built a proof of concept 100% IPv6 network, the full report on all the things right and wrong with it costs quite a bit of money. But for a /. summary, there is much work to be done on the server end. Apache, IIS, python, ruby, perl, PHP, VoIP, SIP/H.323, firewalls and most other server end technologies have a huge amount of development to do, none of them deal with IPv6 properly at all. On the client side, at least at the consumer level, Vista, Mac OSX, linux, BSD, Solaris and all the other modern OSes are quite well advanced, but applications rarely take advantage of the underlying support.

    3G mobile networks utilise IPv6, AIUI; I've a feeling it's part of the specs (well, everything is specified somewhere in mobile telco land), which makes it part of the business model.

  4. um, no. by thegameiam · · Score: 2, Informative

    Bonjour does not rely on IPv6 - IPv6 autoconf was based on Appletalk autoconf, as was Apple's Bonjour (formerly Rendezvous). Bonjour works just fine with no v6 on the network.

    And Apple's business model is absolutely not dependent on Bonjour: I think perhaps you are misunderstanding the term "business model." An example of a business model is:

    "We give away high-quality software for free to get people to buy our hardware, where we make high margins" - that's an example of Apple's business model.

    "By becoming the de-facto standard desktop environment, we encourage customers to buy applications from us which are specifically geared for that environment" - that's an example of Microsoft's business model.

    Notice that neither of those models require calling out a specific technology. Any company which is completely dependent on a single technology will find itself obsolete when the next big thing is created.

    I've done work on their devices more than once and can attest that they are running IPv6 - a separate address for each interface on the device: bandwidth, video, phone. I have been told by their installers that this is typical and that their internal equipment is all running IPv6, though I have no proof of that myself.

    That doesn't mean they're running it. My MacBook right now says this:

    [slamb@spiff ~]$ /sbin/ifconfig en1
    en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULT ICAST> mtu 1500
    inet6 fe80::217:f2ff:fe9c:84f2%en1 prefixlen 64 scopeid 0x5
    inet 172.16.1.4 netmask 0xffffff00 broadcast 172.16.1.255
    ether 00:17:f2:9c:84:f2
    media: autoselect status: active
    supported media: autoselect

    IPv6 auto-assigns link-local addresses, much like the IPv4 169.255.0.0/16 addresses you see when no DHCP is running. I did nothing to set up that "%en1" address, I have never used it, and in fact it can't actually be used anywhere but on that network segment. All this means is that their equipment supports it, which is much more likely than them having upstream IPv6 connectivity and actually learning to use it.

    No one uses IPv6. Your other example is equally bogus. The hospital you mentioned is probably just asking for experience with it because someone saw it in a trade magazine, similar to the people who were asking for "10 years Java experience" when Java had only existed outside of Sun for three years. Or because they know a particular person with IPv6 on his/her resumé and have made the job requirements so (s)he will be the only one who matches them. In a university- or government-run institution, that's how you get around the affirmative action people when you want to hire from within. I have seen it happen at a hospital.

    To quote wikipedia ..."The differences between PPP and market exchange rates can be significant. For example, the World Bank's World Development Indicators 2005 estimates that one United States dollar is equivalent to approximately 1.8 Chinese yuan by purchasing power parity in 2003. [1]. However, based on nominal exchange rates, one U.S. dollar is currently equal to 7.9 yuan. This discrepancy has large implications; for instance, GDP per capita in the People's Republic of China is about US$1,800, while on a PPP basis it is about US$7,204. This is frequently misused to assert that China is the world's second largest economy, but such a calculation would be invalid under the PPP theory..."
