I've used the MaxMind GeoIP Lite database to good success before. Both city and country databases and APIs are available.

An example of usage is:

File dbfile = new File("db/GeoLiteCity.dat");
LookupService lookupService = new LookupService(dbfile, LookupService.GEOIP_MEMORY_CACHE);

Location location = lookupService.getLocation(ipAddress);

// Populate region. Note that regionName is a MaxMind class, not an instance variable
if (location != null) {
    location.region = regionName.regionNameByCode(location.countryCode, location.region);
}
