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: AS9560:RS-ROUTES:AS17705 descr: advertised to AS9560 by Inspire Net Ltd - AS17705 members: 203.114.128.0/18^18-29, 203.79.88.0/23^23-29, 203.96.157.0/24^24-29 admin-c: RPA1-NZRR tech-c: RPA1-NZRR notify: rpsl-admin(a)nzix.net notify: nznog(a)list.waikato.ac.nz notify: james(a)inspire.net.nz mnt-by: MAINT-NZRR-NZ changed: rpsl-admin(a)nzix.net 20050728 source: NZRR REPLACED BY: route-set: AS9560:RS-ROUTES:AS17705 descr: advertised to AS9560 by InspireNet - AS17705 members: 203.114.128.0/18^18-29, 203.79.88.0/23^23-29, 192.138.251.0/24^24-29, 203.96.157.0/24^24-29 admin-c: RPA1-NZRR tech-c: RPA1-NZRR notify: rpsl-admin(a)nzix.net notify: nznog(a)list.waikato.ac.nz notify: brenden(a)staff.inspire.net.nz mnt-by: MAINT-NZRR-NZ changed: rpsl-admin(a)nzix.net 20070720 source: NZRR

TelstraClear RPF and caching
by David Robb 20 Jul '07

20 Jul '07

Hi all, Given the thread over the last couple of days asking how TCL is implementing RPF and transparent caching I thought a semi-official reponse might be useful. We have RPF (the ERXs call it SA Validate) enabled on DSL connections, and the filters applied to the cable modems implement the same functionality there. RPF is not enabled on non-residential services, nor it is configured within the core of the network. Regarding transparent caching, all international traffic passes through the caching infrastructure, although only certain IP ranges are matched for redirection to the caches. There's nothing in there which takes into consideration whether you have a mixed international/domestic link (sorry Philip :). Wholesale customers are very much in the "do not redirect" category, as most are multi-homed and the probability of encountering problems due to asymmetric routing are high. Residentially allocated IP Hi all, The caches themselves spoof the source IP of the client when making an outbound connection to the greater internet, because we've found that although there are occasionally issues caused by asymmetry the problems of cache IPs being blacklisted or DoSd are much fewer. Probably the most commonly observed scenario is where more specific routes are advertised by someone to their upstream (and thus internationally) than domestically (either directly to TCL or via Telecom or whatever) - a number of the routers on the TCL network carry a full routing table, and will prefer the more specific route out via the international path, thus feeding packets to the caches. The return path's then via the path one would normally expect, with the ensuing breakage of port 80 traffic. While this obviously isn't ideal, we do our best to work with the other ISPs to resolve this as fast as possible. --David Robb Network Design Engineer TelstraClear

History of the Internet in New Zealand
by Susi Fookes 19 Jul '07

19 Jul '07

Hi all, InternetNZ has commissioned Keith Newman to write a history of the Internet in New Zealand. The book will go to the publishers later this year. I have read the first few chapters and it is a fantastic read (I look forward to reading it all). He is near the final stages of writing and is now in search of photographs to help document the history. Can you help? If you have a photo(s) that could be of use – please contact Keith (wordman(a)wordworx.co.nz) or myself. And of course we will give you credit in the publication for allowing us to use the image. We are very eager to hear from you!

How many operators out there are using strict RPF? With a lot of interconnection points around the place to me it seems a bit harsh to use strict RPF. And in fact, I wonder if Telstra Clear are using it, since a lot of times I notice broken connectivity due to what appears to be asymmetric routing, and I then have to work around it. It seems to me that the internet is inherently asymmetrical, particularly between ISPs and their carriers. So, can someone please give me the low-down on what the most commonly thing done is w.r.t. asymmetry? Cheers :) Anton

Decent bandwidth required - Invercargill and AKL
by Richard Naylor 15 Jul '07

15 Jul '07

Hi there, I'm looking for some decent bandwidth in Invercargill for an event in August. 2 Mbps symmetric is all I need at the Ascot Park Hotel. Of course we'll always use more than 2Mbps if its available. The main thing is symmetric. Traffic will all be national, with the other end points at AKL and WLG and I'll probably hub out of WLG, so thats where most of the traffic will come from/to. Also looking for the same at ASB Arena (is this the showgrounds ?). It will also hub out of WLG and needs to be around 2Mbps. The event is one day, so we would be looking for (and pay for) connectivity on the Saturday, testing, rehearsals on the Sunday and Live on the Monday. Pack out Tuesday. Please save me the trouble of driving everywhere installing satellite dishes......then pulling them out..... Contact me off list of you can help. Thanks - Rich

gmail blacklisted at ahbl
by Blair Harrison 13 Jul '07

13 Jul '07

Hey folks, I've just discovered[1] that gmail appears to have been listed on the ahbl blacklist, which it appears at least one NZ ISP is using. If you're using the ahbl blacklist then I'd suggest either whitelisting gmail, or dropping this blacklist from your filters, I'd imagine there are quite a lot of legitimate messages getting blocked by this.
