IPv6 Policy Document Revision suggestion
by stuart.prevost＠bt.com 13 Jul '00

All, From reading all the emails it seems that the /48 approach as the *minimum* allocation is the way the IETF would like IPv6 deployment to proceed. However, as it has been demonstrated, the /35 allocations today would only allow for 8,192 /48 per subTLA, and this is assuming that the subTLA holder hasn't split up the NLA block so they can allocate to other providers, in which case this figure could be as small as 256 or lower!!!! I see this as the reason why ISPs consider /48 for a home customer as too large, and hence the sliding-window & /56 discussion at the last RIPE meeting. Now, if the /48 allocation is the way to proceed, I feel that all initial /35 allocations should be initially changed to /29 as the first step. This can be done easily as all allocations have the /29 reserved to ensure a contiguous block. However a /29 allows for 524,288 /48, again if the whole subTLA is used. So at the same time the 80% utilisation section of the document needs to be worded correctly to allow ISPs to apply for subsequent subTLA's. Also I would like to ask the following question: How do we move from the current allocations of /29 & /35 to RFC2374 (IPv6 Aggregatable Global Unicast Address Format) and at what stage will this happen? Otherwise I can see organisations holding multiple subTLA before moving to the address structure in RFC2374, and more renumbering pain.

But that isn't an issue the RIRs need to think about. It is not the RIRs trying to force variable length prefixes. At the RIPE meeting in Budapest and the ARIN meeting in Calgary we reported what the outcome of conversations with IETF people was (the /48, /56, /64 options for allocation). This seemed to be a reasonable way of doing it for the IPv6/ngtrans IETF people and to the RIR people present in Adelaide. At both the ARIN and RIPE meetings, ISPs (the people who will use the address space, after all) were the ones that suggested variable length prefixes for allocation and the RIRs must go by the community consensus (BTW, at the RIPE meeting no consensus was reached, with both the variable length and the 3 fixed lengths having supporters). A second issue is to think about a way of getting the IETF IPv6 people and the 3 RIR communities to talk to each other at the same, otherwise we are entering a loop, with at least 4 separate discussions and each dependant on the other 3.

draft ipv6 wg minutes RIPE 36
by David Kessens 30 Jun '00

30 Jun '00

Hi, Please see below for the minutes of the ipv6 working group session at RIPE 36. I would appreciate your input for corrections, comments or additions. The minutes will be declared final in two weeks if no comments besides typos and small corrections are received within the next two weeks, otherwise we will revise the draft and open a new period of comments. Taking the minutes is not an easy task so I would specifically like to thank Jeroen Bet from the RIPE NCC for taking the minutes. I would also like to take the chance to bring your attention to an agenda topic that we didn't have the chance to discuss: 'I. Input for the 2001 activity plan of the RIPE NCC'. If you have suggestions or ideas, don't hesitate to send them to the list and/or the board of the RIPE NCC.

Administrative stuff - Jeroen Bet was appointed scribe - Agenda was approved with one addition: A presentation from the Ipv6 EVENT in Birmingham (UK) 20000510 by Stuart Prevost under C. B. Status of 6bone http://www.kessens.com/~david/presentations/ David Kessens: The number of sites, allocations have all increased since 20000222. There are now 46 countries represented in 6BONE (was 42). The number of Queries have been once again decreased due to the database downloads by members. C. A presentation from the Ipv6 EVENT in Birmingham (UK) 20000510 http://www.ipv6forum.com/navbar/events/birmingham00/presentations/ Stuart Prevost The IPv6 FORUM event in Birmingham, UK was organised by BT and sponsored by Cisco. It was an overall promotion day for IPv6. The key speakers were Chris Earnshaw (BT) who had a presentation called "The new wave ISP" where he pleaded that ISP's should upgrade now, because the longer the upgrade to IPv6 is postponed, the costlier it will be. Another presentation was by Peter Kirstein (University College London) on the "new Internet" and Mario Campolargo (Head of research Networks - -European Commission) had a presentation on European Strategic Initiatives. The key point here was that the demand for IPv6 has to be there, you can't just say from now on we will use IPv6. Several projects were supported and initiated by the European Commission to promote IPv6. There were several more presentations (Nokia, Ericsson, Telia and others)in Birmingham. More information about the event including the presentations is located at: D. News from the IPv6 forum and meeting in Telluride http://www.ipv6forum.com/ http://www.ipv6forum.com/navbar/events/telluride00/presentations/ (Juergen Rauschenbach) The IPv6 forum has 5 new members, 2 from the US, 2 from the Asia Pacific region and 1 from Europe. A list of members is located at: A 2 day conference was held in Telluride (US) which included a one day tutorial by Florent Parent and Regis Desmeules, Viagenie. Judy Estrin, CTO and Senior Vice President, Cisco Systems gave a presentation which called for *integration* of IPv6 not a *transition*. Furthermore various vendors announced upgrades and new releases of their products which are now compatible with IPv6. will give you an overview of all the presentations during the summit. There are also MP3 files of the key speeches as well as a PDF file of the IPv6 tutorial. The next big IPv6 thing is in London in June, and there is a summit in Japan coming up at the end of the year. Also from November 29th until December 1st there is a 3 day conference on IPv6 in Madrid. E. Status of IPv6 Allocation Guideline draft (Joao) A discussion started following the discussions at the IETF meeting held in Adelaide, especially on whether to use /48s, /56s, or /64s for end-users. One of the obvious problems is the definition of an end-user itself. The issue was raised in the ARIN meeting in Calgary (20000403). The question popped up which direction to take? Should we conserve address-space as much as possible or should we give end-users a little more addresses to make it easier from an administrative point of view. Bill Manning pointed out that these were early days in the IPv6 world, so should we decide on this issue now? Gert Doering brought up the issue of administrative ease. If we issue a /56, it will be easier for ISP's. A lot of people felt that being a bit more flexible is ok but we shouldn't be too flexible. Stephen Burley said that giving an end-user more than what they needed could create complications later on. Some people felt that a /64 was too small but a /48 was too big for an end-user so a /56 would be a good compromise. Wilfried Woeber: we should be cautious about re-shuffling policies. IPv6 is overall more interesting for large networks. Having 8 bits for subnets is not enough. Giving a /64 to any end user that is not big enough to qualify for a /48 could cause problems. Someone pointed out why there was a need to use fixed boundaries when we all use CIDR. David Kessens concluded from the arguments that the attendees brought up that a /64 is not enough as a default assignment. If a LIR issues a /56 or /48 for a default would this be reasonable? Again there was no consensus over this. As the issue of /64 vs. /56 was brought up in the IETF meeting in Adelaide, people started wondering why the IETF is so terrified of giving all end-users 'only' a /64? It seems that the IETF doesn't want NAT to be used with IPv6. Also subnetting and bridging in a /64 is highly undesirable. Giving them a /56 will give end-users the incentive not to do this. Paul Wilson: There is no engineering reason to select a /48 opposed to a /56. a /48 is big enough for any site. However a /48 is way too big for a dial up account -> give them a /64. LIR's should give a /64 for mobile phones, enough for one subnet. There would be no reason for assigning more than a /56 for home use. Assign any length that a user needs in the foreseeable future. We assume a home site will have one provider but every household will have many side addresses. This so far seems not to be anticipated. IPv6 will have to last forever, so do not throw away address-space. Is a floating boundary preferred? Some attendees said yes. It will initiate the end-users thinking process of how much they actually need. It is the ISP's decision of how much address-space to give to an end-user. In fact this would be the same principle that we use for IPv4. There was no consensus over a floating boundary. A question came up what the community will do with the bits we save in the SLA space. What happens if an ISP runs out of space? The question was left unanswered. - -> ACTION on the chair to summarize the discussion and to collect more advise and post it to the IPv6 mailing list. David Kessens concluded that we need to find a balance between conservation and administrative flexibility. F. European developments/initiatives regarding IPv6 topic was skipped because of lack of time G. Reports on on-going projects, success & failures stories on IPv6 topic was skipped because of lack of time H. Future plans for the working group topic was skipped because of lack of time I. Input for the 2001 activisty plan of the RIPE NCC topic was skipped because of lack of time Z. AOB Bernhard Tuy and Laurent Toutain invited all the attendees to the IPv6 platform demonstration in the terminal room set up by Bernhard Tuy, Q: Should we set up a global mailing list for IPv6 issues? There are several now in various regions and it might be an idea to coordinate this. Especially for the discussion about the size of the assignments. 17.00 The meeting was closed
