[ipv6-wg@ripe.net] Call for agenda items and Draft Agenda (v1) for ipv6 wg RIPE47
by David Kessens 29 Dec '03

29 Dec '03

Hi, Below follows the draft agenda (v1) for the ipv6 wg for RIPE47. Note that we are meeting on tuesday instead of the usual wednesday slot. We occasionally change meeting time/date in order to make sure that we are not always scheduled with the same working group so that people who are interested in the other working group have a chance to go to that session for a change. I need your help to make the working group session interesting. Please let me know if you have any suggestions for agenda topics that you would like to have covered during the meeting or if you would like to contribute to one of the 'input of the audience' agenda items. Thanks, David K. --- Draft Agenda (v1) for the IPv6 Working Group Meeting RIPE47 When: 14:00 - 15:30, Tuesday January 27, 2004 Where: St Johns II, Hotel Krasnapolsky, Amsterdam A. Administrative stuff - appointment of scribe - agenda bashing (David Kessens) B. Ranges of allocated ipv6 addresses and their use (Jeroen Massar) C. Global IPv6 routing table status (Gert Doering) D. Report(s) about *actual* v6 traffic volume as compared to v4? *what's real* out there, not what's on powerpoint? (input from the audience) E. Developments/initiatives regarding IPv6 in the RIPE region and beyond (input from the audience) F. Input for the RIPE NCC Activity Plan (input from the audience) Z. AOB ---

There are currently quite some ISP's who filter anything >/35. Generally ISP's should be filtering on allocation boundaries. Thus if a certain prefix is allocated as a /32, they should not be accepting anything smaller (/33, /34 etc) Checking http://www.sixxs.net/tools/grh/tla/all/ 8<------------ The database currently holds 630 IPv6 TLA's. Of which 18 (2.86%) are returned to the pool, 202 (32.06%) IPv6 TLA's didn't have a routing entry. Thus 410 (65.08%) networks are currently announced. 0 (0.00%) only announced a /35 while they have been assigned a /32. 13 (2.06%) announce both their /32 and their /35. - ------------>8 I have to add that there is an error here as 2001:dc0::/35 is in the tables, but doesn't get picked up by the software, will be fixing that soonish. Generally if you announce a /35 it will get through to most ISP's. But we should be avoiding that. Currently the ipv6 global routing table is quite small, but it could grow quite large and when ISP's still don't filter correctly, or better if ISP's don't aggregate it will explode and we will be needing the follow up to BGP soon, which is more work for the IETF :) As for which smoked filled room, this should be a task of the RIRs, thus RIPE's IPv6 WG etc. but it usually takes place when communicating between ISP's. Notice that many ISP's use Gerts list: http://www.space.net/~gert/RIPE/ipv6-filters.html I would applaud a generic /32 that is 'allowed' to being cut up into multiple /48's for the purpose of critical infrastructure. But please, keep it to 1 *documented* /32. That way people will know that they will see more specifics from that prefix and that they should be accepting it too. Currently the !3! IX blocks (2001:7f8::/32 + 2001:504::/32 + 2001:7fa::/32) are seen being announced in pieces too. Maybe these IX blocks, which are common already could be used for assigning 'critical infra' from? This is a RIR thing and should be discussed there (ipv6-wg cc'd). The IETF though should ofcourse advise in all matters.

hi!I am working in a mobile ip6 testbed and i hope you can tell me of a software better than ethereal which can print the binding updates and caches.also if this software has a plotting tool for the desired outputs,it would be perfect.

Gert, You should probably change 2001:500::/32 to 2001:500::/30. This is now documented at http://www.arin.net/registration/ipv6/micro_alloc.html.

-----BEGIN PGP SIGNED MESSAGE----- Hi, At 2003-11-24 RIPE allocated 2001:1700::/27. ISP's doing IPv6 prefixlenght filtering should watch out that they are not filtering out the above prefix It is visible in most parts of the world, check: http://www.sixxs.net/tools/grh/lg/?find=2001:1700::/27 But it is also quite easy to see from that list that many ISP's do filter, somewhat fortunatly, but they do have to update their prefix filters ;) Easiest way to avoid problems is to regulary check: http://www.space.net/~gert/RIPE/ipv6-filters.html Even Gert's 'strict' filters allows the above prefix as it is based on the RIR's policies. A 'golden IPv6 network' page will be created to be able to lookup these prefixes without much problems Greets, Jeroen -----BEGIN PGP SIGNATURE----- Version: Unfix PGP for Outlook Alpha 13 Int.

[ipv6-wg@ripe.net] IPv6 connectivity in Iran
by Henk Uijterwaal (RIPE-NCC) 11 Dec '03

11 Dec '03

Dear All, At the RIPE NCC regional meeting earlier this week, one of the participants asked me about IPv6 connectivity between a local network there and the rest of the world. I had no idea, but promised to post the question here. So: Is there anybody on this list who offers IPv6 connectivity in Iran _today_? Please reply privately, I'll forward the responses and summarize if there is interest.
