Hi I often find the discussions here well beyond my level of understanding, but never the less interesting...I expect that this question may be rather trivial, but this is the only place I could think where I may get an answer... I am trying to discover how I might find out all the IP ranges which are used in New Zealand. My ultimate goal is to check users visiting a website to see if they are connected to the internet within New Zealand and redirect them to different pages accordingly, much like Google seems to be able to do these days, ie when I enter www.google.com, I end up at www.google.co.nz, and I'm assuming that this is done based on the IP address of the machine I'm on...??.. Can anyone point me in the right direction for a source of this information...or if I'm heading in the wrong direction to achieve my goal, enlighten me as to how Google manages this...

The way most people do it is by doing a reverse-dns lookup
on the ip address of the client and looking for .nz at the end
(for example) it will work most of the time.
I have a php script that does that if you are interested.
Probably, the only other way would be to get the AS numbers of all
the local ISP and then find out the address ranges they use, but of
course those keeps changing.

It will work most of the time, but those few who do have .com reverse lookups will fail. I grab a national table from http://noc.win.co.nz/nationalroutes and it's not far off the mark (last time I checked). A national BGP feed is probably the most reliable as that's the way your traffic is going to travel. DNS and ASs sometimes aren't a reliable indicator. Then you have to weigh up the difference between the number of != .nz reverse lookups and missing networks from win and I guess you'll come to the better of the two.

Why limit it to dialup? I can think of at least timaru.com and ihug.net as non .nz reverses that are common. (only timaru.com for dialup though) Then there's the IP numbers without reverse dns...

The hostnames of my home machine and my colocated machine both end in .net - but I still see google.co.nz, not google.com :) I suppose most people who are plain old ISP customers will have .nz hostnames, but there'll be others who dont... especially anyone who has their own domain name (we all know that .com's are generally cheaper than .nz's - I know a few of my clients have realised the same.) - and the ability to get their own DNS set up.

Yep - I don't think I'll ever register a .nz domain again. $15US a year for a .com is just so good in comparison. Good enough infact to just register them on a whim (ThursdayNightCurry.com etc ) =) Dean - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

If you're using Apache, you can do it easily (and much faster) with mod_rewrite (usually within your <virtualhost> container)... RewriteEngine On RewriteLogLevel 0 RewriteCond %{REMOTE_HOST} .*nz$ RewriteRule ^/index.html$ /indexnz.html [L]

True, depending on how well connected you are to your local DNS pump, and how big their cache is.
Messy.

I imagine Google does this by mining the RIR whois data, which will probably give them a geographic mapping which is sufficiently accurate to be useful. If you need accurate data for billing or something, you need to define the question better: for example, the fact that one ISP will route your packets to a particular destination without taking them out of the country is no guarantee that another provider will (or that the return path will stay in-country).

I've read all the other responses about this, and they are all fairly standard -- do it by reverse lookup (not very reliable) or by collecting a listing of networks using routing tables (better but somewhat cumbersome). I do believe that Google and many banner advertises use the services of a company who's name eludes me... However I read about them last year. Their entire business in IP address geo-location, they employ people full-time to keep track of the geographical locations of IP addresses (to the city level in some cases I believe). -- Dylan Reeve - dylan(a)wibble.net It's just not cricket. - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

That reminds me. There is an Apache module for geo-ip. That might be exactly what Steve needs. http://geo-ip.com/downloads/mod_geoip/ -- Andrew P. Gardner barcelona.com stolen, stmoritz.com stays.

claiming to be Andy Gardner,
Dead link (well, it was when I tried it) try this one: http://maxmind.com/geoip/api/mod_geoip.shtml Would ISPs be able to use this service to determine charging for national/international traffic, or would that not work because not all national traffic stays national?

If they had a contract with their customers that said "you get billed at rate X for traffic to or from this particular set of addresses, and at rate Y for other traffic", it would seem like the only service usable for rating. Otherwise, no. Ixia provide that kind of service, incidentally: http://www.ixiacom.com/products/paa/netops/IxMapping.php I've never used it, so I don't know how good it is.
or would that not work because not all national traffic stays national?
The clear sales people used to sell people bundles based on "national" and "international" taffic, but that's really not what they were selling. The "national" category consisted of packets carried within clear's network towards their destination (or from the source, for inbound traffic to the customer) without crossing one of clear's international circuits; the "international" category was everything else. In other words, the distinction was enforced through measurement and control on the international circuits themselves, and not by measuring general traffic and rating it afterwards. So, you need to describe your terms more exactly. Under clear's use of "national traffic", all national traffic "stays national" by definition, and your question makes no sense.
