IPinfo Java Client Library

This is the official Java client library for the IPinfo.io IP address API, allowing you to lookup your own IP address, or get any of the following details for an IP:

IP geolocation (city, region, country, postal code, latitude and longitude)
ASN details (ISP or network operator, associated domain name, and type, such as business, hosting or company)
Company details (the name and domain of the business that uses the IP address)
Carrier details (the name of the mobile carrier and MNC and MCC for that carrier if the IP is used exclusively for mobile traffic)

Getting Started

You'll need an IPinfo API access token, which you can get by singing up for a free account at https://ipinfo.io/signup.

The free plan is limited to 50,000 requests per month, and doesn't include some of the data fields such as IP type and company data. To enable all the data fields and additional request volumes see https://ipinfo.io/pricing

Quick Start

IP Information

import io.ipinfo.api.IPInfo;
import io.ipinfo.api.errors.RateLimitedException;
import io.ipinfo.api.model.IPResponse;

public class Main {

    public static void main(String... args) {
        IPInfo ipInfo = IPInfo.builder().setToken("YOUR TOKEN").build();

        try {
            IPResponse response = ipInfo.lookupIP("8.8.8.8");

            // Print out the hostname
            System.out.println(response.getHostname());
        } catch (RateLimitedException ex) {
            // Handle rate limits here.
        }
    }
}

ASN Information

import io.ipinfo.api.IPInfo;
import io.ipinfo.api.errors.RateLimitedException;
import io.ipinfo.api.model.IPResponse;

public class Main {

    public static void main(String... args) {
        IPInfo ipInfo = IPInfo.builder().setToken("YOUR TOKEN").build();

        try {
            ASNResponse response = ipInfo.lookupASN("AS7922");

            // Print out country name
            System.out.println(response.getCountry());
        } catch (RateLimitedException ex) {
            // Handle rate limits here.
        }
    }
}

Errors

ErrorResponseException: A runtime exception accessible through the ExecutionException of a future. This exception signals that something went wrong when mapping the API response to the wrapper. You probably can't recover from this exception.
RateLimitedException An exception signalling that you've been rate limited.

Caching

This library provides a very simple caching system accessible in SimpleCache. Simple cache is an in memory caching system that resets every time you restart your code.

If you prefer a different caching methodology, you may use the Cache interface and implement your own caching system around your own infrastructure.

The default cache length is 1 day, this can be changed by calling the SimpleCache constructor yourself.

import io.ipinfo.api.IPInfo;
import io.ipinfo.api.errors.RateLimitedException;
import io.ipinfo.api.model.IPResponse;

public class Main {

    public static void main(String... args) {
        // 5 Day Cache
        IPInfo ipInfo = IPInfo.builder().setToken("YOUR TOKEN").setCache(new SimpleCache(Duration.ofDays(5))).build();

        try {
            IPResponse response = ipInfo.lookupIP("8.8.8.8");

            // Print out the hostname
            System.out.println(response.getHostname());
        } catch (RateLimitedException ex) {
            // Handle rate limits here.
        }
    }
}

Country Name Lookup

This library provides a system to lookup country names through ISO2 country codes.

By default, this translation exists for English (United States). If you wish to provide a different language mapping, just use the following system in the builder:

import io.ipinfo.api.IPInfo;
import io.ipinfo.api.errors.RateLimitedException;
import io.ipinfo.api.model.IPResponse;

public class Main {

    public static void main(String... args) {
        IPInfo ipInfo = IPInfo.builder().setToken("YOUR TOKEN").setCountryFile(new File("path/to/file.json")).build();

        try {
            IPResponse response = ipInfo.lookupIP("8.8.8.8");

            // Print out the country code
            System.out.println(response.getCountryCode());

            // Print out the country name
            System.out.println(response.getCountryName());
        } catch (RateLimitedException ex) {
            // Handle rate limits here.
        }
    }
}

Location Information

This library provides an easy way to get the latitude and longitude of an IP Address:

import io.ipinfo.api.IPInfo;
import io.ipinfo.api.errors.RateLimitedException;
import io.ipinfo.api.model.IPResponse;

public class Main {

    public static void main(String... args) {
        IPInfo ipInfo = IPInfo.builder().setToken("YOUR TOKEN").setCountryFile(new File("path/to/file.json")).build();

        try {
            IPResponse response = ipInfo.lookupIP("8.8.8.8");

            // Print out the Latitude and Longitude
            System.out.println(response.getLatitude());
            System.out.println(response.getLongitude());

        } catch (RateLimitedException ex) {
            // Handle rate limits here.
        }
    }
}

Extra Information

This library is thread safe. Feel free to call the different endpoints from different threads.
This library uses square's http client. Please refer to their documentation to get information on more functionality you can use.

Other Libraries
