Java DB-IP

A simple to use Java library for the freely available DB-IP IP address to city dataset. Requires Java 8

This version was updated by Koo(koo@getswizzle.com) for use storage database using MapDB library.

#Before you begin The entire dataset is loaded into a TreeMap . Make sure that you have about 2 GB of Heap space available to load it.

#Get

With maven :

<dependency>
	  <groupId>in.ankushs</groupId>
	  <artifactId>Java-DB-IP</artifactId>
	  <version>2.0</version>
</dependency>

Or gradle:

compile('in.ankushs:Java-DB-IP:2.0')

The Javadocs for the latest release can be found here

#Instructions In order to get geographical information for an ip address, just pass the dbip-city-latest.csv.gz as a File object to DbIpClient as follows:

File gzip = new File(PATH_TO_dbip-city-latest.csv.gz);
DbIpClient client = new DbIpClient(gzip);

Once the data is loaded from the file into memory , any subsequent invocation of the above code would not re-load the data .

Next,just fetch the data for a ip ,like so :

DbIpClient client = new DbIpClient(gzip);
GeoEntity geoEntity = client.lookup("31.45.127.255");
String city = geoEntity.getCity();
String country = geoEntity.getCountry();
String province = geoEntity.getProvince();
String countryCode = geoEntity.getCountryCode();

System.out.println("city : " + city);
System.out.println("province : " + province);
System.out.println("country : " + country);
System.out.println("country code : " + countryCode);

This prints : 
city : Oslo
province : Oslo
country : Norway
country code : NO

For IPV6, do the same :

DbIpClient client = new DbIpClient(gzip);
String ipv6 = "2c0f:f468:ffff:ffff:ffff:ffff:ffff:ffff";
GeoEntity geoEntity = client.lookup(ipv6);

That's pretty much it.

#Integrating with Spring Boot. Follow the detailed instructions on this blogpost . You can find the Spring Boot Java-DB-IP project here .

#For storage database using MapDB

// Create repository instance.
File dbFile = new File("CUSTOM_DB_FILE_PATH.db");
DbIpRepository repository = new SmallMapDBDbIpRepositoryImpl(dbFile);

// Resource importing process. 
// If you already built database file completly, this step is not required.
// It can takes very long time. (over a hour)
ResourceImporter importer = ResourceImporter.getInstance(repository);
File gzip = new File("PATH_TO_dbip-city-latest.csv.gz");
importer.load(gzip);

// Create lookupService instance using exist repository.
GeoEntityLookupService lookupService = new GeoEntityLookupServiceImpl(repository);
lookupService.lookup(InetAddresses.forString(ip));
