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 data (city, region, country, postal code, latitude and longitude)
• ASN information (ISP or network operator, associated domain name, and type, such as business, hosting or company)
• Company data (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)

Check all the data we have for your IP address here.

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 = new 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 = new 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 = new 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 = new 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.
        }
    }
}

EU Country Lookup

This library provides a system to lookup if a country is a member of the European Union (EU) through ISO2 country codes.

By default, here is the file containing all the EU members. If you wish to provide a different file, 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 = new IPinfo.Builder()
                .setToken("YOUR TOKEN")
                .setEUCountryFile(new File("path/to/file.json"))
                .build();

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

            // Print out whether the country is a member of the EU
            System.out.println(response.isEU());
        } catch (RateLimitedException ex) {
            // Handle rate limits here.
        }
    }
}

Internationalization

This library provides a system to lookup if a country is a member of the European Union (EU), emoji and unicode of country's flag, code and symbol of country's currency, public link to the country's flag image as an SVG and continent code and name through ISO2 country codes.

Following are the file that are loaded by default:

• eu.json
• flags.json
• currency.json
• continent.json

If you wish to provide a different file, 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 = new IPinfo.Builder()
                .setToken("YOUR TOKEN")
                .setEUCountryFile(new File("path/to/file.json"))
                .setCountryFlagFile(new File("path/to/file.json"))
                .setCountryCurrencyFile(new File("path/to/file.json"))
                .setContinentFile(new File("path/to/file.json"))
                .build();

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

            // Print out whether the country is a member of the EU
            System.out.println(response.isEU());

            // CountryFlag{emoji='🇺🇸',unicode='U+1F1FA U+1F1F8'}
            System.out.println(response.getCountryFlag());

            // https://cdn.ipinfo.io/static/images/countries-flags/US.svg
            System.out.println(response.getCountryFlagURL());

            // CountryCurrency{code='USD',symbol='$'}
            System.out.println(response.getCountryCurrency());

            // Continent{code='NA',name='North America'}
            System.out.println(response.getContinent());
        } catch (RateLimitedException ex) {
            // Handle rate limits here.
        }
    }
}

The files must follow the same layout as seen

• eu.json
• flags.json
• currency.json
• continent.json

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 = new 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.
        }
    }
}
