Call for agenda items and draft agenda for ipv6 wg RIPE56
by David Kessens 24 Apr '08

24 Apr '08

During next RIPE meeting, our working group is scheduled to meet on: Wed, May 7, 14:00 - 15:30, in Bordeaux Room, Hotel Palace, Berlin I have prepared a draft agenda (see below) with the all the usual agenda items. At this point, I would like to invite all of you to propose other agenda items that are relevant for the deployment of ipv6 in the RIPE service region. Note that we care more about the technical content of your topic than the presentation method: very brief topics without presentation slides that just need a brief discussion are just as welcome as longer presentations with slides. I would also like to draw your attention to the following: The RIPE NCC is planning to turn off IPv4 connectivity on the wireless network for the duration of around an hour on the wednesday morning. This will allow us to try out how one could survive on an IPv6 only network and to draw attention to all the issues that still need to be worked out in order to make this work 100% seemless for the rest of the Internet users. In order to help you prepare, in addition to the normal dual stack wireless network, there will be an IPv6 only wireless network available during the whole meeting and the RIPE NCC will provide instruction sheets on how to configure various popular operating systems. Obviously, the participants of the IPv6 working group don't need all this as we are already fully prepared for the coming of IPv6. However, you are very welcome to participate by helping other people to get their setup to work with IPv6 or by submitting reports and bugfixes/workarounds on problems that are discovered when trying this out. The actual operational details about this event will be posted by the RIPE NCC. In addition to our working group session and the ipv6 only event, I would like to encourage you to take a look at the plenary agendas. There are a large number of presentations scheduled that touch directly or indirectly on IPv6. I hope this helps and see you all in Berlin, David Kessens --- Draft agenda for the IPv6 Working Group Meeting RIPE56 When: Wed, May 7, 14:00 - 15:30 Where: Bordeaux Room, Hotel Palace, Berlin A. Administrative stuff - appointment of scribe - agenda bashing (David Kessens) B. Quick update from the RIPE NCC regarding ipv6 services (RIPE NCC) C. Experience with ipv6 on the wireless network before, after and during the IPv4 turn-off (RIPE NCC, input from the audience) 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. Follow-up: Global IPv6 routing table status (discussion) (Gert Doering) F. Developments/initiatives regarding IPv6 in the RIPE region and beyond (input from the audience) ... Y.

What is difference among /32 , /48 and /64 as charge?
by Yavuz Maşlak 08 Feb '08

08 Feb '08

We are a LIR as small class. We want to apply for ipv6. Is there a difference as charge apply for between /32 and /64 ? I mean, a LIR who has large class, when that LIR applies for /32 and has it, What does that LIR cost for that ? Also, While We are a LIR as small; 1- Can we apply for ipv6 /32 ? 2- What is difference among /32 , /48 and /64 as charge? Thanks a lot.

[anandb@ripe.net: [dns-wg] IANA introduces AAAA record for K-root]
by David Kessens 05 Feb '08

05 Feb '08

----- Forwarded message from Anand Buddhdev <anandb(a)ripe.net> ----- From: Anand Buddhdev <anandb(a)ripe.net> To: dns-wg(a)ripe.net User-Agent: KMail/1.9.5 Subject: [dns-wg] IANA introduces AAAA record for K-root Date: Tue, 5 Feb 2008 15:10:43 +0100 Dear Colleagues, Yesterday, 4 February 2008, at around 17:00 (UTC), IANA introduced AAAA records for six of the root servers in the root server system. One of these servers is k.root-servers.net (2001:7fd::1), which is managed by the RIPE NCC. This change allows the root zone to be queried over IPv6. The K-root IPv6 prefix is currently anycast from the two global nodes, located in Amsterdam and Miami. The introduction of the AAAA records went smoothly, and we are monitoring the query rate and pattern. We are also collecting more detailed information for future analysis. A graph showing the IPv6 query rate for the last 24 hours can be viewed at: http://ripe.net/news/k-root-aaaa-announcement.html More information about AAAA records in the root zone is available at: http://www.iana.org/reports/root-aaaa-announcement.html Regards, -- Anand Buddhdev DNS Services Manager, RIPE NCC ----- End forwarded message -----

AAAA records to be added for root servers
by Barbara Roseman 07 Jan '08

07 Jan '08

apologies for cross-posting... On 4 February 2008, IANA will add AAAA records for the IPv6 addresses of the four root servers whose operators have requested it. A technical analysis of inserting IPv6 records into the root has been done by a joint working group of ICANN's Root Server System Advisory Committee and Security and Stability Advisory Committee, a report of which can be found at http://www.icann.org/committees/security/ sac018.pdf. Network operators should take whatever steps they feel appropriate to prepare for the inclusion of AAAA records in response to root queries. More information will be posted to the IANA web site during January. Regards, Barbara Roseman IANA General OperationsManager ICANN

2007 IPv4 Address Use Report
by Iljitsch van Beijnum 02 Jan '08

02 Jan '08

2007 IPv4 Address Use Report In 2007, the number of available IPv4 addresses went down from 1300.65 million to 1122.85 million, a difference of 177.8 million addresses. The number of usable addresses is 3706.65 million, so on January 1, 2007 we were at 64.9% utilization and a year later we're at 69.7%. These figures are derived from the records published on the FTP servers of the five Regional Internet Registries (RIRs): AfriNIC, which gives out address space in Africa, APNIC (Asia-Pacific region), ARIN (North America), LACNIC (Latin American and the Caribbean) and the RIPE NCC (Europe, the former Soviet Union and the Middle East). There are two other ways to interpret the same data. The first is simply add up all the address space with a date indicating that it was given out in 2007. That number is 186.93 million addresses. The third method is to compensate for ARIN's record keeping peculiarities (see this Internet Protocol Journal article). This brings the total for 2007 to no less than 196.77 million, the highest number ever. The second-highest was 1991 with 189 million addresses. The 196.77 million figure is approxmately 19% higher than the 2005 and 2006 numbers, which were largely the same. All numbers only include addresses that are still in use. For the first time in many years, in 2007 one of the old class A blocks was returned to IANA: block 46.0.0.0/8, 16.78 million addresses in size, is now part of the global pool of free address space. This accounts for most of the difference between the 177.8 and 196.77 numbers. The status of the 221 usable blocks of 16.78 million address is now as follows: Delegated to Blocks +/- 2007 Addresses (millions) AfriNIC 2 +1 33.55 APNIC 26 +7 436.21 ARIN 27 452.98 LACNIC 6 +2 100.66 RIPE NCC 26 +4 436.21 Various 49 -1 822.08 End-user 42 -1 704.64 Available 43 -12 721.42 In addition to the 43 unused blocks (721.42 million addresses) that IANA holds, there is additional free space in the form of addresses delegated from IANA to the regional internet registries, but not yet further delegated by the RIR in question to an ISP or end-user. 2006-01-01 2007-01-01 delegated delegated free delegated delegated free TO BY TO BY AfriNIC 16.78 6.39 10.39 33.55 11.97 21.58 APNIC 318.77 297.23 21.54 436.21 366.87 69.34 ARIN 452.98 350.48 102.50 452.98 394.08 58.90 LACNIC 67.11 42.71 24.40 100.66 57.52 43.14 RIPE NCC 369.10 317.62 51.48 436.21 378.35 57.86 Total RIRs 1224.74 1014.43 210.31 1459.61 1208.79 250.82 Various 838.86 671.26 167.60 822.08 671.48 150.60 End-user 721.42 704.64 16.78 704.64 671.09 33.55 Available 922.74 16.78 905.96 721.42 16.78 704.64 Total 3707.76 2407.11 1300.65 3707.75 2568.14 1139.61 This view uncovers two inconsistencies: block 7.0.0.0/8 that is part of the free space according to the IANA IPv4 address space overview shows up as delegated to the US Department of Defense in ARIN's records. Net 14.0.0.0/8 is for the "public data net" (see RFCs 3330 and 1700) so it's not part of the regular delegation system. 43.0.0.0/8 is delegated to "Japan Inet" by IANA. Those delegations used to be registered in ARIN's database but this block was transferred to APNIC in 2007, where it does show up in the whois service, but not as part of the delegated address space in the files on the FTP server. The total of 3707.76 (or 3707.75) million addresses is slightly different from the 3706.65 maximum mentioned earlier because the latter excludes all RFC 1918 private address space, the former still includes 192.168.0.0/16 and 172.16.0.0/12. The size of address blocks given out was increasing until 2005, but now shows a downturn. The table below shows the number of delegations for a certain range of block sizes (equal or higher than the first, lower than the second value). (2005 and earlier values from 2006-01-01 data, 2006 and 2007 values from 2007-01-01 data. No correction for the ARIN accounting method.) 2001 2002 2003 2004 2005 2006 2007 < 1000 474 547 745 1022 1309 1507 1830 1000 - 8000 1176 897 1009 1516 1891 2265 2839 8000 - 64k 868 822 1014 1100 1039 1192 1015 64k - 500k 262 163 215 404 309 419 395 500k - 2M 39 29 46 61 60 57 62 > 2M 5 5 6 7 18 17 24 The increase in large blocks has a very dramatic effect while the small blocks are insignificant, when looking at the millions of addresses involved: 2001 2002 2003 2004 2005 2006 2007 < 1000 0.16 0.18 0.25 0.35 0.44 0.51 0.63 1000 - 8000 4.47 3.23 3.45 4.49 5.07 5.83 6.93 8000 - 64k 12.81 11.35 14.00 15.99 15.46 18.01 15.67 64k - 500k 32.19 20.28 25.51 42.01 34.23 50.86 50.83 500k - 2M 24.64 21.30 31.98 44.63 41.63 46.69 45.50 > 2M 14.68 12.58 12.58 20.97 68.62 52.43 67.37 Despite the strong increase in the number of 2 million+ blocks and the amount of address space given out in these blocks, the average block size has been going down because of the very large growth in the numbers of smaller blocks: 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 2006 5457 174.32 31945 2007 6165 186.92 30320 The 2568.14 million addresses currently in use aren't very evenly distributed over the countries in the world. The current top 15 is: 2007-01-01 2007-01-01 change Country 1 - US 1408.15 M 1366.53 M +3% United States 2 - JP 141.47 M 151.27 M -6% Japan 3 (4) CN 135.31 M 98.02 M +38% China 4 (3) EU 120.35 M 115.83 M +4% Multi-country in Europe 5 - GB 83.50 M 93.91 M -11% United Kingdom 6 - CA 73.20 M 71.32 M +3% Canada 7 - DE 72.46 M 61.59 M +18% Germany 8 - FR 67.79 M 58.23 M +16% France 9 - KR 58.86 M 51.13 M +15% Korea 10 - AU 33.43 M 30.64 M +9% Australia 11 (12) IT 24.04 M 19.14 M +26% Italy 12 (11) BR 23.46 M 19.27 M +22% Brazil 13 (16) MX 21.50 M 16.26 M +32% Mexico 14 (13) ES 20.42 M 18.69 M +9% Spain 15 - NL 19.89 M 18.08 M +10% Netherlands The -6% and -11% figures for the UK and Japan are once again anomalies: the former is the missing 43.0.0.0/8 net and in the latter case, ARIN and RIPE both had a record for 25.0.0.0/8 in the 2007-01-01 data, but this was cleared up in the 2008-01-01 data. Although the US still added more than 40 million new addresses to its immense existing stockpile, its growth was modest percentage-wise and it now holds 55% of the IPv4 address space in use, down from 57%. All of the other countries in the top 15 except for Canada and "EU" saw their address use grow faster than the 7% average. This brings the total for the top 15 excluding the US to 35%, up from 34%. The rest of the world gets the remaining 10%, up from 9%. See http://www.bgpexpert.com/addrspace2007.php for a copy of this report and links to the versions for 2006 and 2005.

RIPE NCC Makes Record Number of IPv6 Allocations
by Alex Le Heux 14 Dec '07

14 Dec '07

This announcement was posted on the RIPE NCC News & Announcements webpage yesterday: RIPE NCC Makes Record Number of IPv6 Allocations The months of October and November 2007 set new records for the number of IPv6 allocations made in a single month by the RIPE NCC. 24 allocations were made to RIPE NCC members in October, arecord immediately broken by the 31 allocations made in November. The previous peak was 19 allocations in a single month, which was achieved on three separate occasions in 2003, 2004 and 2007. This surge in demand for IPv6 address space follows recent changes in the IPv6 allocation policy, which made it easier to get IPv6 allocations. The increase also comes in the wake of the publication of the RIPE Community Resolution on IPv4 Depletion and Deployment of IPv6. This statement, released immediately after the RIPE 55 meeting in Amsterdam in October, urged all Internet industry stakeholders, including ISPs, governments and regulators, to take steps to foster the accelerating deployment of IPv6. The text of this resolution can be found at: http://www.ripe.net/news/community-statement.html The deployment of IPv6 across the Internet has been a subject of growing global interest, particularly as it relates to the diminishing pool of free IPv4 address space, and the impact that this will have on the ongoing growth and future stability of the Internet. For more information on this, please send an email to <ncc(a)ripe.net>. Best regards, Alex Le Heux Policy Implementation and Coordination, RIPE NCC

IPv6 policies & BGP announcements
by Clement Cavadore 28 Nov '07

28 Nov '07

Hi, I have a few question regarding IPv6, and policies. I am not LIR, so I cannot get any /32 for my network usage. I got from my LIR a /48 for my internal network needs, and another /48 for another end-user, routed through my network. The two /48 are consecutive, and aggregable as a single /47. - Am I allowed to announce a prefix more specific than my LIR's /32 (originated from my ASN, not the LIR's one) ? - If I can announce a more specific prefix, do I have to announce a couple of /48s, or may I announce a single /47, originated from my AS ? If I can announce the /47, I assume the LIR has to create a route: object ? - Is there any recommendations I'd need to know for such a situation (except becoming LIR, which is not possible for us at the moment) ? Thank you for your help -- Clément Cavadore
