How To

This packages contains the core DB-IP class, a CSV database import tool, and sample lookup code.

Here are the few steps needed to import a CSV file into your local database instance using the tools above :

Create a database table

The first step is to create a new database table to hold the imported data.

If you are updating an already populated and running database, it is recommended you create a new table and use an atomic rename to switch the old with the new once the import is finished.

This is the MySQL table creation statement for the IP to ISP lookup table needed by our supported query library and import tool :

CREATE TABLE `dbip_lookup` (
  `addr_type` enum('ipv4','ipv6') NOT NULL,
  `ip_start` varbinary(16) NOT NULL,
  `ip_end` varbinary(16) NOT NULL,
  `continent` char(2) NOT NULL,
  `country` char(2) NOT NULL,
  `isp_name` varchar(128) NOT NULL,
  `as_number` int(10) unsigned DEFAULT NULL,
  `usage_type` enum('corporate','consumer','hosting') DEFAULT NULL,
  `connection_type` enum('dialup','isdn','cable','dsl','fttx','wireless') DEFAULT NULL,
  `organization_name` varchar(128) NOT NULL,
  PRIMARY KEY (`addr_type`,`ip_start`)

Use dbip-update to load the database

dbip-update is the preferred way for loading and updating databases. The tutorial below will guide you through installation, initial database import and setup of automatic updates :

Other resources

These packages are not maintained by the DB-IP team but we have selected them because they provide added functionnality or language support.


ZORAN.DB.IP.Importer is a tool that imports into Microsoft SQL Server the freely available geolocation database offered by



Geocode IP addresses with a single Ruby if statement. No network access, no context switches, no delay, just one low-calorie lookup like Geolocal.in_spain?(request.remote_ip).

500,000 individual lookups per second is fairly typical performance.



This project leverages a simple Java webapp that acts as a wrapper around the geoip databases.
