RIPE 554 Errata Page
by Wilhelm Boeddinghaus 17 Jan '14

17 Jan '14

Dear colleagues, as shortly discussed in Dublin I suggest to set up an errata page for the RIPE 554 document. Errors have been found, and we cannot change anything in the document without getting a new RIPE document number. But having to many different versions of the document confuses our audience. A errata page would make it possible to document minor but important changes of the content of the document. If the group says "yes" we could ask RIPE to help with a page like this. It should be easily reachable from the download page of RIPE554. Kind regards, Wilhelm Boeddinghaus

Follow up on RIPE67 IPv6 Only experiment
by Marco Hogewoning 10 Jan '14

10 Jan '14

Dear colleagues, Just to let you know that, based on experience in Athens, I put up a blogpost on Circle-ID about running IPv6 only. http://www.circleid.com/posts/20131212_are_we_ready_to_switch_off_ipv4/ Would also love to hear from you wether we should aim to repeat this experiment in Warsaw. Or maybe you have an idea of something else that you think is worth trying, please let us know. Best, MarcoH -- "Life is like riding a bicycle.

A well-attended event, it included presentations and discussions about IPv6 deployment strategies, as well as presentations by operators reporting back on their successful IPv6 pilot projects and plans to roll out IPv6 in the first half of 2014. The 14th Saudi Arabian Task Force Meeting, was held on November 7th, 2014 in Riyadh. This successful event, hosted by the Communication and Information Technology Commission (CITC), had over 40 participants from the Saudi Arabian Internet Industry as well as representatives from government institutions and enterprises, discussing the deployment of IPv6. The meeting was preceded by a three-day MENOG IPv6 Roadshow. 21 participants took part in this technical training, learning how to configure and deploy IPv6 in their networks. Dr Ibraheem Al Furaih (CITC), in his presentation, highlighted the fact that the number of Internet users in Saudi Arabia is still rapidly growing, surpassing 16.5 million in the first half of 2013. With the global and regional IPv4 address pool depleted, a rapid deployment of IPv6 is necessary in sustaining future growth and to enable the remaining 45% of the population to also connect to the Internet. He also announced that, following the decision of the Task Force to put more focus on enterprise networks, CITC will run a pilot in which four enterprises will be supported in enabling IPv6 on all their customer-facing services. Ashraf Sattar (STC) reported back on a successful pilot project in enabling IPv6 on their DSL network. With the tests completed, they expect to begin rolling out IPv6 as a production service in the first quarter of 2014, followed by a planned deployment of IPv6 in the FTTH network in the second quarter. He also highlighted some of the design challenges that mobile operators are facing, concluding that a single stack approach, in which an IPv6-only service is complemented by an IPv6 to IPv4 translation service, is the most promising solution. However, as he remarked, such a solution would put limits on the peer-to-peer communication in between hosts. Motaz Alturayef (Mobily) provided the attendees with an overview of some of the security challenges in deploying IPv6. But as he mentioned, the fact that a lot of devices and software now have IPv6 capabilities, also poses a threat in that IPv6 traffic might escape to the attention of the security teams and intrusion detection systems. Amer Mustafa (GAMA) presented on the successful projects they did with several of their customers. Their segmented approach that focusses on different parts of the organisation allows for the deployment of IPv6 in only 90 days. He stated that convincing the business executives and decision makers was the biggest challenge in the fast deployment IPv6. A presentation by Marco Hogewoning (RIPE NCC) showed statistics about the deployment of IPv6 in Saudi Arabia taken from the various measurement programs, comparing them to those of other countries in the Middle East region, as well as to the global deployment statistics. He also highlighted that, while the IPv4 pool is depleted, there is still an ongoing need in maintaining the registration data of IPv4 resources to be accurate and complete. Gert Doering in his role as IPv6 Consultant explained the various options available within the RIPE NCC Service Region for obtaining IPv6 resources. Using several examples, he highlighted some of the drawbacks and benefits of those options for companies of various sizes. He invited the participants to take part in discussions in the RIPE Address Policy Working Group, which have been addressing several potential changes to IPv6 and IPv4 address policy. In conjunction with the IPv6 events, the RIPE NCC also invited its Saudi Arabian members, together with other stakeholders, for an informal dinner to discuss ongoing issues and the needs of the membership. The attendees expressed the need for further activities in IPv6 training, not only on a technical level but also for executive-level employees. They also welcomed the continued efforts made by the RIPE NCC to increase its presence in the Middle East, noting the expansion of the Dubai office to include more staff. All the presentations, as well as more information about the Saudi Arabian IPv6 Task Force, are available on their website, via http://www.ipv6.sa./The next meeting of the Task Force is planned to take place in April or May 2014.

I read the presentation; It has some benefits and some problems. This kind of IPv6 addressing maybe decrease network security and it will give opportunity to hackers to access to the special networks by special IPv6 address scanning.

Should we go on and produce a BCP document of some kind? As the author of this addressing plan (https://ripe67.ripe.net/presentations/222-ripe67-yanodd-ipv6-addressing.pdf) , my main motivation for presenting it was to show that it is possible to encode basic information in an addressing plan (without wasting too much space) and still keep it simple . For example, even IPv4 addressing plans were location-aware, that's nothing new. Well, its even easier and more effective in IPv6 addressing, because of the number of bits available. As far as encoding service type, no space is wasted because it is encoded after the /56 boundary ;) , even making it possible for QOS. As I mentioned in the presentation, this is our 3rd or 4th try over the past ~10 years. So far, with the help of some basic heuristics, it seems to be working out fine cheers, Yannis > > Otherwise: violations of the KISS principle are rarely a good idea. > In this case, you might find out that you snuck yourself into a > straightjacket a few years down the line. > > regards, > spz ------------------------------ Message: 2 Date: Sun, 27 Oct 2013 07:54:42 +0000 From: Benedikt Stockebrand <bs(a)stepladder-it.com> Subject: Re: [ipv6-wg] 96 more bits... time for some magic after all?

That's what I meant by "unnecessarily 'depleted'". If they actually grow beyond their /29 or whatever, let them have another prefix. What I wouldn't want to see however is that some big player gets some extra address space because they wasted their existing one. Once that happens, everyone will demand the same. And yes, I've had these discussions. In particular, the idea to bit-encode the services (i.e. significant port numbers) somewhere in the subnet prefix. Eventually these people decided "well, we have a /12 for IPv4, so it's only fair we also get a /12 for IPv6".

A /56 is fine for today's requirements, but if this hype about the "Internet of Things" really takes off and you want to put things into different subnets, a /56 may occasionally be a problem even for consumer households. Not today, but think anything from ten to fourty years. > However IPv6 is big enough that most people will not feel any pain with > it, some however will start to get into trouble in 5-10years time, guess > more like around in 7 years.

I don't see any reason why size has to do with it. The problem is more of a ratio between size and allocated address space---and the technical knowledge around. (And no, unlike somebody else on this list I don't believe it feasible for a consumer to call in a CCIE every time they need some networked deviced hooked up.) > There was major discussion just to get that /56 into the documents. > Upto that point there was /64 pr.LAN, /48 for the rest.

It has been part of the specs for long enough that a number of implementations will rely on it.

Additionally, anything that can be (mis-)configured exponentially adds (or rather, multiplies) to the frustration potential for end users. > Doesn't this sound like A/B/C-class network vs CIDR?

96 more bits... time for some magic after all?
by Shane Kerr 31 Oct '13

31 Oct '13

All, [ gah... hit the wrong key and sent this unfinished ] We saw two presentations by network architects at the RIPE meeting that used bits in their IPv6 addressing plan to carry meaning beyond simple network topology and packet routing. For example, declaring a specific bit in the address to be 1 for voice traffic or 0 otherwise. There are motivations for doing this, which may or may not be valid in any particular case. There are ways to lessen the amount of addresses consumed by this (for example by assigning /56 instead of /48 to end users). But I think that the important thing is that we have historically not considered this sort of use with address allocation policy. In face, RFC 2050bis was *just* published as RFC 7020: http://datatracker.ietf.org/doc/rfc7020/ This includes the long-standing historical goals of conservation, aggregation, and accuracy. Using bits in IPv6 networks for other purposes is orthogonal to those goals. What should we do about it? Cheers, -- Shane
