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.

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.

Area/PoP, that is a just a way to describe a route into a certain direction. I guess the wording should be changed to resolve the issue I have with it, eg "try to aggregate per area/PoP where possible to keep IGP routes low" > However, ARIN is not > in the business of recommending routing best practices so the > recommendation was narrowed to just "don't aggregate by POP" meaning > "don't fine-tune your aggregation all the way down to the POP level; > stop somewhere above it." Then put that in there, sounds more logical than the "Don't aggregate" line that is in there now. As for the rest of your mail, I would suggest putting it in the Wiki as an explanation and referencing it from the above point as it clarifies a number of things that people will not have to time to go lookup in the mailinglists.

Re: v6 subnet size for DSL & leased line customers

Thus why didn't you request a larger prefix from ARIN then? Clearly you can justify it. Then again, if you are going to provide /56's to home users, nobody will think you are a bad person and most people will be quite happy already. In your case I would then reserve (probably topdown) /48's, for the larger sites/businesses and start allocating bottom-up for /56's to endusers. ------------------------------------------------- I haven't requested anything yet. That's why I came to you folks. To learn and then get busy on it. Thanks for your top-down and bottom-up idea. I will probably also intersperse /56s in between allocations as well; filling them in later if it ever gets to that. scott

Re: v6 subnet size for DSL & leased line customers

First, thanks everyone for the discussion. I learned more from this than a LOT of other discussions on IPv6. I now have a plan and I didn't before... It looks to me that one really has to know his customer's needs to plan out the allocation of IPv6 space. That leads me to believe that a /56 is going to work for everyone on this network because, at this time, only very, very few of our largest customers might possibly have a need for more than 256 /64 subnets. In fact, almost all household DSL customers here only have one LAN and I could get away with /64s for them because they wouldn't know the difference. But in an effort to simplify the lives of the network folks here I am thinking of a /56 for everyone and a /48 on request. Now I just gotta wrap my brain around 4.7x10^21 addresses for each customer. Absolutely staggering. scott --- randy(a)psg.com wrote: From: Randy Bush <randy(a)psg.com> To: Joel Jaeggli <joelja(a)bogus.com> CC: nanog(a)merit.edu Subject: Re: v6 subnet size for DSL & leased line customers Date: Thu, 27 Dec 2007 13:19:27 +0900 >> vendors, like everyone else, will do what is in their best interests. >> as i am an operator, not a vendor, that is often not what is in my best >> interest, marketing literature aside. i believe it benefits the ops >> community to be honest when the two do not seem to coincide. > If the ops community doesn't provide enough addresses and a way to use > them then the vendors will do the same thing they did in v4. i presume you mean nat v6/v6. this would be a real mess and i don't think anyone is contending it is desirable. but this discussion is ostensibly operators trying to understand what is actually appropriate and useful for a class of customers, i believe those of the consumer, soho, and similar scale. to summarize the positions i think i have heard o one /64 subnet per device, but the proponent gave no estimate of the number of devices o /48 o /56 o /64 the latter three all assuming that the allocation would be different if the site had actual need and justification. personally, i do not see an end site needing more than 256 subnets *by default*, though i can certainly believe a small minority of them need more and would use the escape clause. so, if we, for the moment, stick to the one /64 per subnet religion, than a /56 seems sufficient for the default allocation. personally, i have a hard time thinking that any but a teensie minority, who can use the escape clause, need more than 256. hence, i just don't buy the /48 position. personally, i agree that one subnet is likely to be insufficient in a large proportion of cases. so keeping to the /64 per subnet religion, a /64 per site is insufficient for the default. still personally, i think the one /64 subnet per device is analogous to one receptacle per mains breaker, i.e. not sensible. > there are three legs to the tripod > network operator > user > equipment manufacturer > They have (or should have) a mutual interest in: > Transparent and automatic configuration of devices. as you have seen from chris's excellent post [0] on this one, one size does not fit all. this is likely another worthwhile, but separate, discussion. > The assignment of globally routable addresses to internet > connected devices i suspect that there are folk out there who equate nat with security. i suspect we both think them misguided. > The user having some control over what crosses the boundry > between their network and the operators. yup randy --- [0] - <http://www.merit.edu/mail.archives/nanog/msg04887.html>

Ok folks, what's the plan? I think we should opt to join each others company at either Brasserie Jo's, or Blu. I can't speak for Jo's NYE, but Blu NYE has optional fireworks viewing on their deck facing the common. Should be pretty awesome. $99 bux. Significant others invited, of course, and anyone else who may be straggling on NYE. Let's do something together. It's long overdue. Marty

Carrier Hotels in Chicago
by Robert Boyle 29 Dec '07

29 Dec '07

Hello all, I located our new midwest datacenter site, but I'm going to need connectivity to Chicago. At which other middle of the country places should we connect? We will obviously connect back to our network in New York and Los Angeles, but I'm not familiar with other carrier hotels or IXs in the middle of the US. What is in Dallas? Does anyone have any strong feelings about Telx in <http://www.telx.com/facilities.php?section=ChicagoIL350ECermakRoad>Chicago, IL @ 350 E. Cermak Road or <http://www.telx.com/facilities.php?section=ChicagoIL600_780SFederalSt>600 S. Federal Street? Are those the best places in the midwest? Any other suggestions? I am asking here because I am looking for a carrier and ISP perspective. I am going to colocate core and edge routers and I need connectivity to a large pool of carriers and no MRC on cross connections. Any help or advice would be appreciated.

The one i did find was > Terremark, but no others yet. Adam, If you want connectivity to Latin America (inc. S. America) from the US (LA & NY), then you probably want to be at NOA in Miami. That is a Terremark facility, but lots of carriers are there. Look at their carrier customer list and you will see all of the carriers connected to them in Miami: http://marketplace.terremark.com/bysegment.asp?s=1 We have a few connections which go through NOA and we have found the pricing to get high speed circuits to NY and LA from Miami to be very reasonable. Good luck with your project. -Robert Tellurian Networks - Global Hosting Solutions Since 1995 http://www.tellurian.com | 888-TELLURIAN | 973-300-9211 "Well done is better than well said." - Benjamin Franklin
