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.

But, if another person on the same segment as the original requester want's the same stream, they just "listen" on that that particular muticast address.

Currently, a router needs to know about all multicast groups that are being sent through it, and where they should be forwarded to. If multicasting becomes more widespread, the amount of multicast groups will soar, and thereby the multicast state will exceed what current routers can handle.

      Correct me if I'm wrong in something here... The scalability problem is partly taken care of with Rendez Vous points, but I'm not entirely sure about those. Basically, they are local control points for routers on a given network, so that some state is lifted from the routers.

You get a new address there on at your temporary location, but you have the option of going mobile with your old IP address, which means that anyone who wishes can reach you at your old address as if you were still at your regular location.

      Basically, the way it works is this: if your permanent address is XYZ, you head over to some remote network and grab temporary address ABC (from, say, a DHCP server). Then, you send a special message back to your regular "home" router saying, "hey, I'm temporarily at address ABC." Thenceforth, when a packet arrives for you at your regular address, the router sends back a message that's sorta similar to a "host unreachable" message, but instead it says, "yeah, he's reachable, but for right now, you have to use address ABC to get to him." The great thing about this scheme (that you can't really do with IPv4 and/or tunneling) is that subsequent packets go straight to the temporary address, because the originator of the packet has been informed of the temporary address. And since it's part of the IP-level protocol, the application doesn't have to know anything about it.

      Mainly this is meant for laptops that need to roam and keep the same IP address. But, there's a variety of other cool uses for it. For instance:

      • You've got yourself an ISP that doesn't want to give you a static IP address. No problem -- find a friend who does want to give you one, and live in perpetual roaming mode. The extra work for your friend's router and extra bandwidth for their network is minimal because it's only one packet in and one packet out per remote connection.
      • If you'd like, you can set up all your machines (those with static IP addresses, at least) so they can go mobile. Need to move half your servers to another building or another room for some construction in the server room? No problem -- just move them and they'll still be accessible by their original address. There is no need to change the DNS temporarily or anything like that. (In fact, if you need to, you can move every machine in the building, and they can all keep their original addresses, even if they are temporarily split up between 15 different buildings.)
      • Say someone from work is sick or has a broken leg and wants to work from home for a few weeks. They want to take their Linux workstation home and use it, but you still want to be able to login to their machine and apply patches (or check things out when they have support questions). They can just take the machine home, and you can continue to ssh into it as if it were still on their desk at work.

      Some of these things can be done with things like Cisco VLANs, but they require extra work, proprietary equipment, etc. Mobile IPv6 is a standard way of doing it that should work Internet-wide and totally automatically.

Note that is is virtually impossible for a small business to be dual homed and have things work when one of the links goes down.

      I have to agree with you.

      Where I work we have a number of linux lan-to-inet routers at small buisness customers. We once tried going all SSH on the routers a number of years ago, but then an OpenSSH remote exploit was discovered and we had a massive problem where we have dozens of routers out there with a vulnerable SSHd, and some of them are very hard to reach, on intermittant dialups where it takes a while to upload and install new software (particularly since the customer is actively using the connection at that time). We got everything patched, but then I think there was another openssh vulnerability discovered, and finally we decided to just turn SSH off and use telnet for remotely managing them. I've never heard of a machine being exploited due to a vulnerability in the telnet server implementation.

      Now that's not to say I don't believe in SSH. I haven't installed a production machine aside from these routers with telnet server on it in years. I wouldn't concieve of using it on anything else. But when you've got tons of embedded-like systems in a 500 mile radius of you with intermittant and/or slow internet connections and no other way of reaching them, it is realy crucial that they not get exploited. The best way to do that is to run as few services as possible, and make sure those services are as simple as possible to reduce the possibility of bugs being found. Telnet is pretty damn simple...

So shame on the IETF for not having solved that problem with a fundamentally new way to do routing in conjunction with the development of an addressing technology that now way overscales the ability to route it.

If you don't want the real world applications to all do that in a slightly different way, you'll have to make it part of the standard.

    One thing that nobody has ever been able to satisfactorily explain to me is how the global end-to-end routing that IPV6 offers will operate in practice.

    IPV4 can't be routed in this manner, because of router resource limits and the unreliability of route information - e.g. keeping route information for every individual /24 would overload most routers currently in use, and that John J. Average can advertise routes for microsoft.com and traffic goes down a black hole.

    CIDR (Classless Internet Domain Routing) alleviates both these problems to some degree by removing the ability to effectively route any address block smaller than a /16. Since the only people who can realistically maintain a /16 are ISPs, mega-corps or state institutions, this basically takes the 'dream of a global network in which everyone is connected', breaks its legs and ties it directly to the financial interests of it's largest players.

    Some would say (and I would largely agree) that the commercial benefits to infrastructure providers of offering routing to the 'smaller' nodes on the internet are non-existent or negative. So it just won't happen.

    CIDR + IpV6 gives us nothing we don't already have. It simply offers more addresses behind each NAT machine - and really, nobody I have ever heard of is NATing more machines than will fill the 192.168.0.0/16 + 10.10.0.0/16 blocks.

    I could be wrong, maybe new routing protocols have been developed to handle IPv6 routing out to network's edge, and maybe these protocols have been adopted as industry standards and are present in the firmware of all IPv6-capable hardware from the vendors that matter.(I don't imagine it will be a problem to deploy this stuff to 'software' routers)

    I, along with many others, desperately want to be able to take advantage of the internet's fault-tolerance, but are prevented from doing so by CIDR etc. More addresses don't mean anything unless they are visible from more than one upstream point.

    The internet has already reached its commercially supportable size limits, in terms of route-branches. It can still grow in terms of users, but becomes more and more vulnerable to destabilisation and control by the manipulation of single entities as it does.

    IPv6 is a solution in search of a problem, and it won't be adopted, ever, unless there is either:

    1) A wholesale replacement of router infrastructure coupled with a sudden burst of altruism from the corporations that own that infrastructure

    2) A revolution on routing algorithms, resulting in the massive reduction of route-table storage and lookup cost - maybe quantum computing combined with a cheap and compatible framework for deploying QC devices

    3) A widespread IPv6 tunneled network becomes prevalent - P2P networks are the pioneers of this type of thing, but it is unclear how such a network could perform, given the constraints imposed by the underlying IPv4 system, and given this situation it is quite likely that it will be more efficient to devise a new protocol than to do IP-within-IP.

    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.

    The need for IPv6 is in the future. Way in the future. But we can go ahead and use it today if we solve some issues (some technical, like routing, and some political). But taking address space back from early adopters is not going to encourage them to use IPv6 directly. Hopefully the universal reachability of it will.

  136. Multihoming by LostOne · · Score: 1

    Until there is a *viable* multihoming solution that actually works in the real world rather than on paper, my organization cannot even consider switching. We currently multihome on IPV4 but we cannot qualify for the requirements for provider-independent addresses for IPV6. Because of this, if we moved to IPV6, even if our upstreams supported it, we could not provide the same level of reliability that our IPV4 network has; we'd be tied to a single provider for provider-aggregated space in IPV6 which would not allow us to keep our IPV6 network visible if that one provider (or our link thereto) failed.

    For those of you who think that multiple links to a provider will solve that problem, think again. How many times has a typo in a router configuration caused routing issues on a backbone?

    Thus, when there is a multihoming solution that is workable for the smaller companies who need to it (and size != need to multihome in this market - you can't get big if you can't multihome), we cannot deploy it for critical services.

      But doesn't using encapsulated IPv6 inside IPv4 packets create an ugly overhead in packet sizes?

      Of course. But there's no choice, since it's impractical to create an alternate IPv6-only Internet immediately.

      Slightly off-topic, but not quite: IPv6 headers alone are not quite as bloated as it might seem. Though they contain 4 times as much address data (since each address is 4 times larger), they are only double the size of IPv4 headers. They're also much easier for intermediate routers to process because there is no IP header checksum. A lot of the fields of the IPv4 header have been removed and turned into optional extension headers (the Protocol byte has been renamed Next Header and is the start of a daisy chain of optional headers culminating in the TCP/UDP/ICMP/whatever header).

      So for now, IPv6 moves through the IPv4 internet through encapsulation. This winds up wasting 20 bytes per packet. The bigger problem of IPv6 is that people who use tunneled connections often wind up with pessimal routing because the underlying IPv4 topography is not always reflected in the IPv6 routing table. Obviously when the migration is complete that won't be the case, but for now it's the best we can do, and the payoff is that it gives everyone experience with the new stuff.
