Call for agenda topics & draft agenda (v1) for ipv6 wg RIPE52
by David Kessens 23 Apr '06

23 Apr '06

During next RIPE meeting, our working group is scheduled to meet: Thu Apr 27, 17:00-18:00, room Dolmabahce I have prepared a draft agenda with all our standard items. However, the meeting will only be a success if we get a lot of active participation from all our participants. To achieve this goal, I would like to invite everybody to bring up their own topics on the list, or directly to me. Topics should be relevant to the operational issues regarding ipv6 deployment. Note that we don't require you to bring powerpoint slides or whatever, neither does a topic need to be of a particular predefined length. We are more interested in the content of the topic! Obviously, you are also very welcome to volunteer somebody else than yourself to give a presentation and to lead a discussion on a topic that is of interest for our working group. Thanks! David Kessens --- Draft Agenda (v1) for the IPv6 Working Group Meeting RIPE52 When: Thu Apr 27 2006, 17:00-18:00 Where: Room Dolmabahce, Ceylan Intercontinental Hotel, Istanbul Turkey A.

Re: [ppml] PI addressing in IPv6 advances in ARIN

Hi all, My first idea was submitting a PI IPv6 policy proposal next Monday to RIPE and the rest of the regions, trying to get a consensus for a "global" policy on this, but as this thread is being followed up in several mail exploders, to avoid a long cross-posting, I think it will be better to start some discussion already in a mailing list which is global, and actually I think we have the right one ... global-v6(a)lists.apnic.net So, if you aren't subscribed in the global-v6(a)lists.apnic.net, and you're interested in this thread, please subscribe at http://mailman.apnic.net/mailman/listinfo/global-v6 If you're late because the Eastern, the archives are also available at http://www.apnic.net/mailing-lists/global-v6/ Regards, Jordi > De: JORDI PALET MARTINEZ <jordi.palet(a)consulintel.es> > Responder a: <jordi.palet(a)consulintel.es> > Fecha: Fri, 14 Apr 2006 13:39:07 +0200 > Para: "v6ops(a)ops.ietf.org" <v6ops(a)ops.ietf.org>, "ppml(a)arin.net" > <ppml(a)arin.net>, "shim6(a)psg.com" <shim6(a)psg.com> > Conversación: [ppml] PI addressing in IPv6 advances in ARIN > Asunto: Re: [ppml] PI addressing in IPv6 advances in ARIN > > Hi Owen, > > You said it: If somebody find the good solution, it will be attractive to > the people to go for it.

Problems with ipv6 router
by Andrei Robachevsky 13 Apr '06

13 Apr '06

Dear Colleagues, [We are sorry for any duplicate mails you might receive] This afternoon we experienced a problem with our IPv6 router. Problems started at 13:50, and we are still facing problem. None of our IPv4 services are affected, as these are dealt with by other routers. Affected services, which we offer on IPv6 are: - FTP: ftp.ripe.net - WWW: www.ripe.net - DNS: ns*.ripe.net - Whois: whois.ripe.net We suspect that an interfacecard of our dedicated IPv6 router is faulty, and at the moment an engineer is working on it. The long term solution is that we will replace this router. We apologise for any disruption or delay this may have caused. If you have any further questions about this matter, please send an e-mail to ops(a)ripe.net. Kind regards Andrei Robachevsky CTO, RIPE NCC

2005 IPv4 Address Use Report
by Iljitsch van Beijnum 01 Jan '06

01 Jan '06

According to AfriNIC, APNIC, ARIN, LACNIC and RIPE NCC statistics as published on their respective FTP servers, they gave out 165.45 million IPv4 addresses in 2005. Out of 3706.65 million usable IPv4 addresses, 1468.61 million are still available as of januari 1, 2006. Breakdown by Regional Internet Registry over the past few years: 2000 2001 2002 2003 2004 2005 AfriNIC 0.56 0.38 0.25 0.21 0.51 1.89 APNIC 21.08 28.84 27.08 33.08 42.92 53.97 ARIN 30.96 32.76 21.02 22.14 33.51 36.30 LACNIC 0.88 1.57 0.65 2.62 3.77 11.04 RIPE NCC 24.88 25.39 19.94 29.72 47.75 62.25 Total 78.35 88.95 68.93 87.77 128.45 165.45 AfriNIC gives out address space in Africa, APNIC in the Asia-Pacific region, ARIN in North America, LACNIC in Latin American and the Caribbean and the RIPE NCC in Europe, the former Soviet Union and the Middle East. Note that the RIRs tend to change their records retroactively from time to time. For instance, the januari 1, 2005 records show that only 117.3 million addresses were given out in 2004. Also, reclaimed address space isn't listed explicitly. From the fact that the 1-1-2005 records show 1939 million addresses given out before 2004 but the 1-1-2006 records show 1928.48 million addresses for the same period, we can conclude that 11.15 million addresses given out before 2004 have been reclaimed in 2005. The Internet Assigned Numbers Authority (IANA, part of ICANN) keeps an overview of the IPv4 address space at http://www.iana.org/ assignments/ipv4-address-space. The list consists of 256 blocks of 16.78 million addresses. Breakdown: Delegated to Blocks Addresses (millions) AfriNIC 1 16.78 APNIC 16 268.44 ARIN 23 385.88 LACNIC 4 67.11 RIPE NCC 19 318.77 Various 50 838.86 End-user 43 721.42 Available 65 1090.52 Of the 1895.83 million addresses delegated to the five Regional Internet Registries, 1517.74 million have been delegated to end-users or ISPs by the RIRs, and 378.09 million are still available. Along with the 1090.52 million addresses still available in the IANA global pool this makes the total number of available addresses 1468.61 million. The size of address blocks given follows an interesting trend. The table below shows the number of requests for a certain range of block sizes (equal or higher than the first, lower than the second value). 2000 2001 2002 2003 2004 2005 < 1000 326 474 547 745 1022 1309 1000 - 8000 652 1176 897 1009 1516 1891 8000 - 64k 1440 868 822 1014 1100 1039 64k - 500k 354 262 163 215 404 309 500k - 2M 19 39 29 46 61 60 > 2M 3 5 5 6 7 18 The number of blocks in the two smallest categories have increased rapidly, but not as fast as the number of blocks in the largest category, in relative numbers at least. However, the increase in large blocks has a very dramatic effect while the small blocks are insignificant, when looking at the millions of addresses involved: 2000 2001 2002 2003 2004 2005 < 1000 0.10 0.16 0.18 0.25 0.35 0.44 1000 - 8000 2.42 4.47 3.23 3.45 4.49 5.07 8000 - 64k 18.79 12.81 11.35 14.00 15.99 15.46 64k - 500k 35.98 32.19 20.28 25.51 42.01 34.23 500k - 2M 12.68 24.64 21.30 31.98 44.63 41.63 > 2M 8.39 14.68 12.58 12.58 20.97 68.62 The medium-sized blocks seem most affected by the burst of the internet bubble. Another way to look at the same data: Year Blocks Addresses (M) Average block size 2000 2794 78.35 28043 2001 2824 88.95 31497 2002 2463 68.93 27985 2003 3035 87.77 28921 2004 4110 128.45 31252 2005 4626 165.45 35765 The 2222.38 million addresses currently in use aren't very evenly distributed over the countries in the world. The current top 15 is: Country Addresses US 1324.93 M United States JP 143.00 M Japan EU 113.87 M Multi-country in Europe CN 74.39 M China CA 67.43 M Canada DE 51.13 M Germany FR 45.16 M France KR 41.91 M Korea UK 40.18 M United Kingdom GB 33.63 M Great Britain AU 26.87 M Australia IT 18.39 M Italy BR 17.17 M Brazil NL 16.40 M Netherlands ES 16.29 M Spain The US holds 60% of the IPv4 address space. The other countries in the list together hold another 32%. A copy of this information and a tool to perform queries on the base data is available at http://www.bgpexpert.com/addrspace2005.php

New IPv6 Address Block Allocated to the RIPE NCC
by filiz＠ripe.net 31 Dec '05

31 Dec '05

[Apologies for Duplicates] Dear Colleagues The RIPE NCC received the IPv6 address range 2A01:0000::/16 from the IANA in December 2005. 2A01:0000::/23 was allocated to the RIPE NCC in July 2005. This latest range includes that previous allocation. You may wish to adjust any filters you have in place accordingly. You can find more information about the IP space administered by the RIPE NCC on our web site at: https://www.ripe.net/ripe/docs/ripe-ncc-managed-address-space.html Regards, Filiz Yilmaz RIPE NCC

They all reflect back to how thing was done with IPv4 and those ways are doomed to fail with IPv6 simply due to the size of the IP space. Last I checked around there were some promissing new proposal on the way for how to solve this very basic problem. And in the meantime, drop the thought about multihoming and PI space, start to think about other ways to use the possibility IPv6 give us. Just to mention maybe the biggest advantage, we have that extended header part of IPv6, it give us endless possibilities. and yes I do have some idea about how it can be done but no one really bother to consider geo-based IP's either so... :) Not to forget it quite likely will undermine the entire business case for how ISP's today operate. -- ------------------------------ Roger Jorgensen | rogerj(a)stud.cs.uit.no | - IPv6 is The Key! http://www.jorgensen.no | roger(a)jorgensen.no -------------------------------------------------------

Real-world IPv6 SMTP experience
by Florian Weimer 27 Dec '05

27 Dec '05

Hi, is there any document that contrasts RFC 3974 with the real world? I try to create a set of MX RRs which includes an IPv6 MX host, does not negatively impact reachability from v4-only hosts (or v6-enabled hosts without v6 connectivity), prefers v6 over v4 when possible, and does not waste any IPv4 addresses. This is what I've come up with so far: deneb.enyo.de. 172800 IN MX 9 v6.mail.enyo.de. deneb.enyo.de. 172800 IN MX 10 v4.mail.enyo.de. v6.mail.enyo.de. 172800 IN A 212.9.189.167 v6.mail.enyo.de. 172800 IN AAAA 2001:14b0:202:1::a7 v4.mail.enyo.de. 172800 IN A 212.9.189.167 The A RR of v6.mail is necessary because some broken anti-spam checks reject mail from deneb.enyo.de if they cannot find an A record for the primary MX. The v4.mail MX host is needed because some MTAs suppress A record lookup if they discover an AAAA record (even if there's no v6 connectivity available). I wouldn't be too surprised when this setup leads to bouncing mail, too. 8-> Florian
