IP Address Geolocation database
- axod 18y ago>> Q). "how accurate is the data? A). Very accurate. The database is updated during the first week of each month." Be nice to have a better idea of why this is more accurate than say MaxMind GeoIP, how much more accurate it is, where the data comes from etc.
- swombat 18y agoAgreed... GeoIP works great for us so far, and is free. Is there any good reason to change?
- binarray2000 18y agoCould you point me to the free GeoIP database?
- inovica 18y agoA search of google for this shows: http://www.maxmind.com/app/geoip_country http://www.maxmind.com/app/geoip_country
- brl 18y agoThe free GeoIP databases are deliberately crippled with inaccuracies. Their business model is to sell you an upgrade to the good information.
- axod 18y agoI've been using it for about 9 years. If all you need is country resolution, it seems pretty much spot on, and very useful. I haven't seen anything that is all that accurate beyond that. Most geo location (for the UK anyway), pegs people at the ISPs head quarters, rather than their actual location. Which isn't really very useful.
- coglethorpe 18y agoI'd like to know the souce of the data and how it compares to other databases. It might be good for a prototype, but there's no telling the real quality of the data.
- streety 18y agoI'm all for competition in this space but I'm left with some questions. "How accurate is the data? Very accurate. The database is updated during the first week of each month." To me this is not acceptable. Firstly, I want numbers and not a vague assurance. Secondly, I'm dubious whether a brand new service in this space is going to be, what I would consider to be, very accurate. This isn't to say that the service is without merit just that I want a little more info and a little less marketing hyperbole.
- streety 18y agoI've just found this forum post: http://blogama.org/node/87 http://blogama.org/node/87 The claim is 99.5% accuracy. Whether that is reproducible and whether it holds outside the US is unknown.
- maurycy 18y agoWe will see. The competition is (nearly) always good.
- binarray2000 18y agoFolks... he gives us the database for FREE! We can use it or leave it. I would hope that someone downloads the damn thing, compares it against his GeoIP and tells us his findings. Otherwise, the discussion about accuracy is silly.
- tc 18y agoI was trying to find a free SQL database of IP geolocation with country, city, region, latitude and longitude for a project but none was accurate and up to date so I decided to create my own and now I offer it for free. He makes it sound as though this isn't particularly difficult or expensive. Does anyone want to speculate on the method he is using to compile this data? For his zipcode database he seems to be running mass queries on the Google Maps API. Simply doing mass WHOIS queries to the regional registrars only gets you data about the corporate headquarters of the ISPs, which I suppose could be enough depending on the level of granularity that is acceptable to you. (presently a similar question on his forum, posted by someone else, is unanswered: http://blogama.org/node/105 http://blogama.org/node/105)
- Locke 18y agoSomeone on reddit claims it's an exact copy of this: http://www.maxmind.com/app/geolitecity http://www.maxmind.com/app/geolitecity I haven't verified that claim.
- rmaccloy 18y agoFrom page (quoted in some other comment below): "Very accurate. The database is updated during the first week of each month." This is also the frequency at which Maxmind releases updates. So...
- mpk 18y ago.. so perhaps he's pulling the data from some of the same sources as Maxmind does and hence is on a similar update schedule, is what you're implying, right? Anyway, I'd still like to know what those sources are.
- jasonkester 18y agoThis is gold. I spent a lot of time a few years back looking for something like this, and the existing solutions were just terrible. Like the author says, there just wasn't a usable dataset out there. Mostly there were a bunch of bad web APIs wanting to charge money for wildly inaccurate data. So yeah, this might still be inaccurate, but it's a huge step forward. Thanks!
- Sam_Odio 18y agoThis seems very interesting. I definitely think there's a need for competition to MaxMind's free geoip database. I registered openipdb.(org|com) a year ago with the intention of doing that but never got around to it. Is anyone interested in taking this data and turning it into a legit open source project? Let me know and I'll donate the domain name :) You'd have to contact the author and make sure the data has an open license, but my guess is that he's OK with it.
- chime 18y agoHere's one I made (and maintain) that doesn't need a database: http://chir.ag/projects/geoiploc/ http://chir.ag/projects/geoiploc/ but it only does Country name, not city/region. My file is updated once a day and is basically one giant PHP array. It works quite well for parsing through logs and I've used it on many of my hi-demand sites with some caching.
- savrajsingh 18y agoI use maxmind.com's javascript API. It works great, is easy and free, and is up to date.
- naj 18y agoMy openHosting account in Virginia returns (for xml) the lat/long (35.685,139.751) of the Japanese Imperial Palace. Not sure what that means.
- jmtame 18y agoAny databases exist for reverse geocoding? (start with long,lat and finds city, state?)
