[swinog] Geolocating IP's
hello everybody Is anybody of you aware, how the most popular services (Google, Zattoo, Facebook, etc) are matching geographic locations to ip-adresses ? Our AS (41666) is located in CH, so also all the ripe objects are registered with country-code CH. Now we have a customer located in Germany, so I created a inetnum-block with his subnet in ripe-db with country-code DE. This was a week ago. The customer is still complaining that he is constantly redirected to the swiss-versions of all the services. Does anybody of you experienced a similar problem ? Does anybody knows proper solution ? Thanks for any advice in advance Best regards Stefan Renner Stefan Renner Network Engineer MYGATE Translumina Networks AG Flurstrasse 50 CH-8048 Zürich Fon: +41 44 540 22 11 Fax: +41 44 540 23 46 stefan.ren...@mygate.net www.mygate.net ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog

So far, the most accurate data I've seen are from countries.nerd.dk - whether they use that, I don't know. -- Per Jessen, Zürich (13.9°C) ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
Re: [swinog] Geolocating IP's
Dear Stefan One possible source of that problem could be outdated databases of a geolocation service provider. There are some commercial providers (e.g. ip2location.com) which offer geolocation of IPs as a serivce. This makes sense sometimes, when e.g. a network spans multiple regions and/or countries and you still want to know, where a specific IP is located. Those service providers do not only rely on the public IP databases such as RIPE, but also on other information (probably confidential, how they exactly do it). The downside is, that they do plausibilty checks and it might be, that it seems unplausible to them, that a german customers has a Swiss upstream...? Only one of a gazillion possible reasons...

hello everybody Is anybody of you aware, how the most popular services (Google, Zattoo, Facebook, etc) are matching geographic locations to ip-adresses ? I don't expect somebody from Google coming forward ;-) My guess(es): - Google: they built their own database, based on data available from commercial providers (maxmind) - Facebook: dito, of course with less engineering effort than Big G. - Zattoo: probably uses Maxmind's dataset with little local modifications There's not much you can do IMO. If some website thinks you are in country X, and refuses to provide certain services as a result, the only solution is to complain to the website directly and ask them to update their databases. I don't think people can read the RIPE databases in realtime. Rainer ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog

According to our books of wisdom (KXCD, Dilbert, ...), people enter their geoIP by themselves: http://xkcd.com/713/ :) Is anybody of you aware, how the most popular services (Google, Zattoo, Facebook, etc) are matching geographic locations to ip-adresses ? ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
Re: [swinog] Geolocating IP's
Hello Stefan Does anybody of you experienced a similar problem ? Does anybody knows proper solution ? I assume most of the geo-ip-stuff is based loosely on RIPE-DB. But I am pretty sure you need a few month until changes in RIPE-DB will be reflected in the geo-ip-databases. Seen that before. A customer got a PI-Allocation which before was present in Belguim. The Google frontpage was looking very different because they lost a case in court and had openly to appologize. :) A few month after changing the location in RIPE-DB the problem was solved. So either you can persuade the opeator of that site to update his own location-db or simply wait a few month. YMMV. Now we have a customer located in Germany, so I created a inetnum-block with his subnet in ripe-db with country-code DE. Just one last thought: is this customer really located in Germany? I mean: I have customers which are registred in Panama or on Mauritius (no kidding!) still I set the country-code for these networks to Switzerland because the users of those IPs (the servers actually) are here in Switzerland. -- Best regards, Roman Hochuli Operations Manager nexellent ag Saegereistrasse 29 CH-8152 Glattbrugg Phone: +41 44 562 30 40 Fax: +41 44 562 30 41 URL: www.nexellent.ch X-NCC-RegID: ch.nexellent Imagination is the one weapon in the war against reality. -- Jules de Gaultier ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
