What's Your Timeline for IPv6 Migration?

SgtChaireBourne asks: "IPv4 has, over the last 20 years, seen unexpectedly wide adoption. During this time it's proven to be both flexible and robust, but also several problems, though once small, have grown. IPv6 looks to solve some scalability problems, add needed privacy and authentication mechanisms, address quality of service, and provide better routing and addressing capabilities. What kind of timeline does your site/institution/business have for rolling out IPv6 and how?" Those interested in IPv6 migration may also be interested in this article, from a year ago.

The hip venue these days is OASIS, you can get a spec finished in less than 2 years in OASIS - and when it is done it does not look like some shite that came off a teletype.

      The folk in charge at the IETF these days are the second stringers, not the visionaries. They simply do not have what it takes to deploy IPv6 and they are scared of making a bad choice so they make no choices at all which is usually the worst choice.

      The only major companies still involved in IETF in a big way are CISCO and Microsoft. And Microsoft is only there because they feel they need the cover. There are some Sun engineers still attending, but that seems to be as much as anything to keep their visibility up and their resume looking fresh.

      IPsec may have been intended for Internet security, but it suffers from several assumptions that were obsolete years ago - namely that hosts are meaningful as security principals, and IP addresses are good names for hosts. HIP goes a long way to alleviate some of those problems. The other thing that IPsec needs is a good API to make it accessible to applications, and in particular to allow applications to set their own authentication credentials and use their own security policies.

      But I'd agree that IPsec hasn't turned out to be a boon for IPv6 - if anything it has delayed IPv6 deployment without adding useful functionality. Hindsight is perfect, of course.

      It also means that users on larger networks are actually accountable. if you have a way of uniquely identifying a machine from outside the network, abuse complaints actually mean something. if the secret service comes knocking on a network admin's door complaining about threats being sent from your network to president@whitehouse.gov you can't say "oh, we don't have any way of knowing which user sent that mail, because it didn't go through our mail server and all 5,000 machines on this network connect to the internet through the same IP address." chances are that you aren't logging every connection that goes through your nat gateway, and so your basically stuck holding the ball on that one.

      Global IPv6 addresses don't work. Most client computers around the Internet can't talk to a server on a global IPv6 address, and most server computers around the Internet can't talk to a client on a global IPv6 address.

      of course they do. every host in my home network has a globally routable ipv6 address (thanks to hurricane electric's tunnelbroker.net) and i can reach hosts at my colo provider that are set up via freenet6. i can also reach hosts at my school that are directly connected to the ipv6 backbone via nysernet.

      All the operating systems I use have been claiming ``IPv6 support'' for years. But they still require manual action by the system administrator before they can talk to IPv6 addresses.

      no they don't. radvd is like dhcpd on steroids. if your hosts are ipv6 capable, start up radvd on your ipv6 connected router and within seconds every one of them will have their own globally unique, routable ipv6 address.

      (All of this boils down to a small protocol design error in IPv6. A small change to IPv6 software would make IPv6 addresses work without any administrator action. I have a web page, http://cr.yp.to/djbdns/ipv6mess.html [cr.yp.to], explaining this in much more detail.)

      this page basically says two (false) things.

      1) you can't use ipv6 and ipv4 at the same time, so if you switch to ipv6 now you can't reach 99.9% of the internet.

      this is blatently false and you know it. ipv6 and ipv4 can co-exist on the same machine very well. on my ipv6 enabled network, every host has an ipv4 address from 10.0.0.0/8 and an ipv6 address from 2001:470:1f00:321::/64. my machines try to look up AAAA records on hosts first, and if one exists they try to connect to that ipv6 IP. if no AAAA record exists, or the host is unreachable via ipv6, the machine falls back to ipv4, looks up a host, and connects.

      2) it takes a massive amount of work to convert all applications over to ipv6 and no one has even started on such a task.

      this one is even more confusing. i've got ipv6 enabled apache, ipv6 enabled qmail, ipv6 enabled djbdns, ipv6 enabled mozilla/phoenix, ipv6 enabled xchat, ipv6 enabled internet explorer, etc. all of these applications on every modern OS have all been written to use ipv6 first, then fall back on ipv4.

    Ever heard of MSDP? Not perfect, but there's plenty of work going on here.

    Who ever said that it needed to support something other than real-time (read audio/video)?

    There are some real life applications in use today that a couple of large cable operators use to redistribute things like VoD content to multiple sites.

    The Nasdaq uses mcast on the trading floor for live video, and also to remote sites.

    While it's largely an enterprise type application, there are some areas where ISP's can benefit from it especially as we start to see more and more streaming applications.

  50. Helping out open source projects by dmeranda · · Score: 4, Informative

    You have to just jump in! I too am already using IPv6 comfortably alongside my routed IPv4 network. I actually forced myself to start using it just 'cause, and it's wonderful. The autoconfiguration features are worth it alone. And I have a mixed network of Linux, AIX, HP-UX, Windows 2000, and Cisco. My bind/DNS is configured for IPv6, my sendmail is configured for IPv6, and so on. But the underlying IPv4 network is still there right along side. There's really no reason to not go ahead and start experimenting with IPv6, to get comfortable with it before you depend on it.

    Actually my excuse to start playing with it was I was developing an application which could make use of multicasting. And let me tell you, IPv6 multicasting is a dream come true when compared with IPv4! And the sockets-API is much more sane and complete, after all the IETF learned from the shortcomings of the IPv4 API. See these wonderful resources and just jump in!

    So now that I'm enjoying it, I've been seeking out open source applications that use IPv4 and providing assistance to the developers to get them compatible with IPv6. A lot of the smaller projects in particular could use help, as some of them are unnecessarily tied to the IPv4 stack and probably don't even know it nor know anything about IPv6. I also suggest that anybody with some expertise to lend a hand as well. The open source/free software community can not find itself falling being here.

  51. No IPv6 support even where it all begins.. by Yanster · · Score: 2, Insightful

    Up until last year I have been developping firmware (embedded server load balancing) for the new line of switch/routers of a big company that shall remain nameless.

    At no point were we instructed to even think about IPv6. IPs are internally encoded on 4 bytes, in various and sometimes rather obscure locations within the code. They can even be found as fixed-size strings for ASCII representation for command-line processing.

    From what I have seen the rest of the firmware, all the way down to the proprietary ASICS's internal registers, it has no provision whatsoever for IPv6.

    Given the amount of work needed I doubt this line of switch/routers (edge & core) will ever support it, despite the fact that this is a new product and the next generation won't come out until 2-3 years - if there's any.

  53. All those little things by NilsK · · Score: 2, Interesting

    I took a look into v6 and found some nice things in there. But I wouldn't want to use it currently. Having PA-Addresses on every networkstation in our internal network and not having to use NAT sounds like a good Idea. Until you change your provider. Big renumbering ante Portas. And the autoassignments might be nice, only I do not trust them yet. There will always be boxes configured by Hand.

    And then there is the vendor support. Not only the software missing (that was mentioned before), but also the missing Hardware: I'm talking about network printers, Barcodescanners, telephonesystems, powerswitches ... All that little things, already supporting IP. They only can do v4.

    So we cannot switch until all the devices we need support it. And that won't be the case within the next 5 to 10 years I guess.

  55. Mostly there, with caveats by anticypher · · Score: 3, Informative

    I've IPv6 enabled on all my machines, my upstream provider offers IPv6, and most of my former clients have IPv6 rolled out internally. It doesn't buy much for the moment, but I've noticed a large surge in interest over the last year in the techie community to learn all they can about IPv6. I know one guy who is staking his whole future on being the IPv6 guru.

    Having been at several RIPE meetings and national Net Operator Group meetings, the biggest problem is getting peering and transit connections negotiated. IPv6 requires many things which were optional in IPv4, like multicast support end-to-end. Many of the clued ISPs and carriers in Europe now have IPv6 internally, and offer it to their clients. Larger ISPs are naturally lagging behind, because the techies have no voice in the business operations of big telcos, and the suits haven't heard enough to start asking their customers if they want it.

    There was a chicken and egg problem, where ISPs weren't asking their customers about wanting IPv6, and customers not implementing it because it wasn't offered by IPSs. This has changed quite a bit in the last year, for two reasons. Big telcos rolling out 2.5G/3G mobile phone systems are using IPv6 internally, and smaller ISPs are looking for an edge in these lean times. My upstream ISP made a few announcements on internal mailing lists about offering IPv6 over IPv4 tunnels for testing purposes, and was overwhelmed by the response. They now have a few dedicated cisco routers, and allow a full IPv6 login without needing tunnels. The last I heard, almost 20% of their customers have taken up IPv6, mostly the businesses with clued techies and home experimenters. Other ISPs are now looking to roll out IPv6 soon, but the biggest problem is hammering out the peering/transit issues, not in the offer to customers.

    The other delay is waiting for the IPv6 working groups at RIPE to get the registry database objects well defined and implemented, and a few other technical services like route servers and DNSSEC implemented. But the work is ongoing and will take a while until the backend issues get ironed out.

    My bet is that, at least in Europe, there will be some mainstream buzz about IPv6 starting in 12 to 18 months. The early adopters like myself already run IPv6 alongside IPv4, most systems have it built in ready to go, and ISPs are getting up to speed.
