h1. geoip h2. 'Geographic info for an IP address' h2. What GeoIP searches a GeoIP database for a given host or IP address, and returns information about the country where the IP address is allocated, and the city, ISP and other information, if you have that database version. h2. Installing
sudo gem install geoip
h2. Prerequisites You need at least the free GeoIP.dat, for which the last known download location is "http://www.maxmind.com/download/geoip/database/GeoIP.dat.gz":http://www.maxmind.com/download/geoip/database/GeoIP.dat.gz or the city database "http://www.maxmind.com/app/geolitecity":http://www.maxmind.com/app/geolitecity This API requires the file to be decompressed for searching. Other versions of this database are available for purchase which contain more detailed information, but this information is not returned by this implementation. See www.maxmind.com for more information. h2. Example
    require 'geoip'
    GeoIP.new('GeoIP.dat').country("www.netscape.sk")
    => ["www.netscape.sk", "217.67.16.35", 196, "SK", "SVK", "Slovakia", "EU"]


    GeoIP.new('GeoCity.dat').city('github.com')
    => ["github.com", "207.97.227.239", "US", "USA", "United States", "NA", "CA", "San Francisco", "94110", 37.7484, -122.4156, "America/Los_Angeles", 807, 415]
