##GeoIP API for node.
####Emergent Update####
Warning: Due to the Asynchronous programming problome,
Any version that below the 0.1.3 dosen't work in any real script.
I highly recommond that every user should update to at least v0.1.3!

###Install
npm install geoip
###Usage
####Country Information
// Open the country data file
var country_data = geoip.open('/path/to/GeoIP.dat');
1, Synchronous methods, network independence.
geoip.Country.code_by_addr(country_data, '8.8.8.8'); // Return 'US'
geoip.Country.name_by_addr(country_data, '8.8.8.8'); // Return 'United States'
2, Asynchronous methods, depends on node's async-style dns module.
geoip.Country.code_by_domain(country_data, 'www.google.com', function(err, code) {
if (err) {throw err;}
console.log(code); // prints 'US'
});
geoip.Country.name_by_domain(country_data, 'www.google.com', function(err, name) {
if (err) {throw err;}
console.log(name); // prints 'United States'
});
//Close the opened file.
geoip.close(country_data);
####City Information
// Open the GeoLiteCity.dat file first.
var city_data = geoip.open('/path/to/GeoLiteCity.dat');
1, Synchronous method geoip.City.record_by_addr(city_data, '8.8.8.8'); // Return an object of city information // { // "country_code":"US", // "country_code3":"USA", // "country_name":"United States", // "continet_code":"NA", // "region":"CA", // "city":"Mountain View", // "postal_code":"94043", // "latitude":37.41919999999999, // "longitude":-122.0574, // "dma_code":807, // "metro_code":807, // "area_code":650 // }
2, Asynchronous method
geoip.City.record_by_domain(city_data, 'www.google.com', function(err, reord) {
if (err) {throw err;}
var keys = Object.keys(record);
keys.forEach(function(k) { // Same as record_by_addr
console.log(k + ':' + record[k]);
});
});
geoip.close(city_data);
####Organization Information
#####Get Organization Information#####
// Open the GeoIPOrg.dat first.
var org_data = geoip.open('/path/to/GeoIPOrg.dat');
1, Synchronous method
geoip.Org.org_by_addr(org_data, '8.8.8.8');
// Return an array of the names of organization
// [
// 'Genuity',
// 'The United Way',
// 'Education Management Corporation,
// 'International Generating Co. (Intergen)'
// ]
geoip.close(org_data);
2, Asynchronous method
// This method has a small bug that not resovled yet, not recommend use it.
geoip.Org.org_by_domain(org_data, 'www.google.com', function(err, org) {
if (err) {throw err;}
if (typeof org === 'string') {
console.log(org); // Organization Not Found
} else { // Same as org_by_addr
org.foreach(function(o) {
console.log(o[0] + ':' + o[1]);
});
}
});
#####Get ASN informatioin######
// Open the GeoIPASNum.dat first.
var asn_data = geoip.open('/path/to/GeoIPASNum.dat');
1, Synchronous method
geoip.Org.asn_by_addr(asn_data, '8.8.8.8');
// Return an array of asn objects
//[
// { number: 'AS15169', description: 'Google Inc.' },
// { number: 'AS36597',
// description: 'OmniTI Computer Consulting Inc.' },
// { number: 'AS26471',
// description: 'Smart City Networks' }
//]
2, Asynchronous method
geoip.Org.asn_by_domain(asn_data, 'www.google.com', function(err, asn) {
if (err) {throw err;}
if (typeof ans === 'string') {
console.log(asn) // ASNumber Not Found
} else { // Same as asn_by_addr
asn.forEach(function(a) {
var keys = object.keys(a);
console.log(a[keys[0]] + ' : ' + a[keys[1]]);
});
}
});
geoip.close(asn_data);
####Region Information
// Open the GeoIPRegion.dat first.
var region_data = geoip.open('/path/to/GeoIPRegion.dat');
1, Synchronous method
geoip.Region.region_by_addr(region_data, '8.8.8.8'); // Return 'US,CO'
2, Asynchronous method
geoip.Region.region_by_domain(region_data, 'www.google.com', function(err, region) {
if (err) {throw err;}
console.log(region); // Maybe different from region_by_addr
});
geoip.close(region_data);
####NetSpeed Information
// Open the GeoIPNetSpeed.dat first.
var netspeed_data = geoip.open('/path/to/GeoIPNetSpeed.dat');
1, Synchronous method
geoip.NetSpeed.speed_by_addr(netspeed_data, '8.8.8.8'); // Return 'Dailup'
2, Asynchronous method
NetSpeed.speed_by_domain(data, 'www.google.com', function(err, speed) {
if (err) {throw err;}
console.log(speed); // Maybe different from speed_by_addr
});
geoip.close(netspeed_data);
