Through is a small geolocation web API. You can use it to:
- Look up the location of an IP address
- Find out the time zone for a location
- Get responses in JSON
- Centralise your geographical data so each of your apps don’t need to store it
I didn’t want to reproduce the same functionality across my web apps, so I thought an API would be a good solution.
- Install libgeoip (sudo port install libgeoip)
- Install the ruby binding (sudo gem install geoip_city)
- Get the data: (curl -O http://www.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz)
- Get some time zone mapping data (curl http://www.maxmind.com/timezone.txt > data/timezone.txt)
