Fascinating stuff - thanks for posting it. I find it most interesting that over 60% of DSL users systems know about and use more than 20 protocols. What is the sample size? Just approximate - 100s, 1000s, 10s of 000s ? I can understand if you didn't want to say, but it would help with rough deviation / error % Thanks, Gerard Perry Lorier wrote: > Well, I ran an analysis of DSL customers[1] over the space of 24 hours > [4] to see how many different protocols people were using.

[Fwd: [pacnog] IPv4 exhaustion discussions in Asia Pacific region]
by Andy Linton 18 Feb '07

Given our discussions on IPv4 and IPv6 at the recent nznog meeting some of you may be interested in this. -------- Original Message -------- Subject: [pacnog] IPv4 exhaustion discussions in Asia Pacific region Date: Mon, 12 Feb 2007 10:44:32 +1000 (EST) From: Elly Tawhai <elly(a)apnic.net> To: pacnog(a)pacnog.org Hi You are probably aware by now that the exhaustion of IPv4 address space is likely to occur in the next few years. You might be interested to know that a proposal to deal with IPv4 exhaustion has been put forward for discussion in the APNIC region. The proposal suggests five main principles: (1) Global synchronization: All five RIRs will proceed at the same time for measures on IPv4 address exhaustion. (2) Some Blocks to be left: Keep a few /8 stocks instead of distributing all. (3) Keeping current practices until the last moment: Maintain the current policy until the last allocation. (4) Separate discussions on "recycle" issue: Recovery of unused address space should be discussed separately For more information on the proposal, see: http://www.apnic.net/docs/policy/proposals/prop-046-v001.html This proposal affects the whole Internet community. I encourage you to read the proposal and have your say on the APNIC Policy SIG mailing list, or at the upcoming APNIC 23 meeting in Bali, Indonesia, 26 February - 2 March 2007. If you can't attend the meeting in person, you can still have your say by participating remotely via live chat.

I fully support this style of thinking. Infact, if I was an ISP I would be seriously considering NATing my entire customer base - except for those who were willing to pay $x/mo for a real IP. At the end of the day, with a few exceptions, most protocols work quite well from behind a nat. And it gives me another revenue stream, which if I am an ISP would be quite useful considering I am probably losing money on the DSL I am currently providing. Cheers, Patrick -- patpatnz(a)gmail.com

Or, perhaps worse, all new applications will have an extra layer to "route around" this problem. The rise of application data over XML over HTTP (over SSL) over TCP over IP hints at what this world might be like. That's not exactly progress. The security folks aren't exactly keen on this either (even without the SSL, it's very hard to "pinhole" inspect what is going on in the midst of large XML payloads, and you don't get much of a service type indicator if it's all XML over HTTP). The "big win" of Skype, and Kazaa before it, is its ability to "route around" the NAT everywhere, firewall everywhere, world and overlay what is basically an end-to-end network again (at least bits of it created on demand). That's not exactly progress either. Some other possibilities have been suggested, such as smarter intermediate boxes (firewalls, NAT), with which one negotiates (as in a protocol to request) a path through to the end box. This is already starting to happen with, eg, STUN, but potentially could be formalised as part of connection setup, and done automatically rather than requiring per-application custom setup. One is left wondering if instead of inventing random ad-hoc "tunnel through intermediate boxes" protocols it may be that things converge on, eg, 6-over-4. At least, eg, application over TCP over IPv6 over IPv4 is still pretty transparent, and doesn't have _that_ much overheard (compared with, eg, XML over HTTP). And there's some eventual migration path which involves reducing layers (eventually when everything is 6-over-4 it makes sense to just get rid of the IPv4 bit). Ewen

Notification of NZRR Database changes
by NZRR Database Notifications 13 Feb '07

13 Feb '07

Dear Colleague, This is to notify you that some object(s) in NZRR database which you either maintain or are listed as to-be-notified have been added, deleted or changed. These objects are used to configure the various NZIX route servers (http://nzix.net/) so you can expect the relevant servers to be reloaded in the near future. The reloading of the servers is staggered over a period of time so that if you are peering with both servers at an exchange, you can maintain at least one BGP session at all times and consequently a full set of routes. --- PREVIOUS OBJECT: route-set: AS9439:RS-ROUTES:AS38292 descr: Route set advertised to AS9439 by Zero One - AS38292 members: 210.48.94.0/24^24-29, 210.48.103.192/26^26-29 admin-c: RPA1-NZRR tech-c: RPA1-NZRR notify: rpsl-admin(a)nzix.net notify: nznog(a)list.waikato.ac.nz notify: nick(a)01.co.nz mnt-by: MAINT-NZRR-NZ changed: rpsl-admin(a)nzix.net 20070212 source: NZRR REPLACED BY: route-set: AS9439:RS-ROUTES:AS38292 descr: advertised to AS9439 by ZeroOne (NZ) Limited - AS38292 members: 202.174.6.0/23^23-29 admin-c: RPA1-NZRR tech-c: RPA1-NZRR notify: rpsl-admin(a)nzix.net notify: nznog(a)list.waikato.ac.nz notify: noc(a)zeroone.co.nz mnt-by: MAINT-NZRR-NZ changed: rpsl-admin(a)nzix.net 20070214 source: NZRR
