Map/schematic over NZ Internet connectivity?
Has the NZ Internet connectivity been mapped out yet? Maybe I'm not googling right, but I can't find any resource which lists national and international connectivity for New Zealand. -- Juha
I tried InternetNZ with this very question about a year ago, and the answer was no. -----Original Message----- From: Juha Saarinen [mailto:juha(a)saarinen.org] Sent: Sunday, 13 June 2004 10:01 a.m. To: NZ NOG Subject: [nznog] Map/schematic over NZ Internet connectivity?

I guess there was no follow-up along the lines of "... but we're working on it"?
I wrote a "mesh traceroute" program a while ago that gives a good feel for the topology of the New Zealand internet. http://tr.meta.net.nz/ Traceroute to an international site and you can see the main exit points for the country. Traceroute to an internal site and you can see how people get traffic there. You can put up your own "tr.php" which gives another source to be added into the mesh. Also, Pascal's netlantis project (which he posts about here intermitantly) can provide AS paths between ISP's. Unfortunately it's down right now, although when I talked to him just now he says it'll be back up in a week or two.

It seems to be growing in popularity at the moment... list of urls has damn near doubled since this morning. Maybe this could become the official mapper :) Dave Hall Dave.net.nz

I like it Perry! Any chance of colouring the blobs by AS? ;) Stephen. -- ----------------------------------------------------------------------- Stephen Donnelly BCMS PhD email: sfd(a)endace.com Endace Technology Ltd phone: +64 7 839 0540 Hamilton, New Zealand cell: +64 21 1104378 -----------------------------------------------------------------------

It may be worth mentioning that the Internet looks different (sometimes in fine detail, sometimes in coarse structure) depending on where you measure it from. It's not necessarily useful to divine connectivity without incorporating routing policy, and it's not always possible to discern the routing policy from outside an AS. Mapping Internets is not a well-known science (it's a subject of ongoing research in many places). Joe

So really, we'd need a "live" map, that takes into account routing policy changes etc? Doable? -- Juha

Or something.
Doable?
Do you really expect a one-word answer? :-)
