IP2Location™ LITE IP-ASN Database

Introduction

ASN Database

This database provides a reference to determine the autonomous system and number (ASN). An autonomous system (AS) is a collection of connected Internet Protocol (IP) routing prefixes under the control of one or more network operators as a single administrative entity in routing policy.

It is free for personal or commercial use with attribution required by mentioning the use of this data as follows,

Features

Translates IP address to autonomous system (AS) and autonomous system number (ASN).

Database Fields

Name Type Description
ip_from INT (10) / DECIMAL (39,0)†† First IP address show netblock.
ip_to INT (10) / DECIMAL (39,0)†† Last IP address show netblock.
cidr VARCHAR(43) IP address range in CIDR.
asn INT(10) Autonomous system number (ASN).
as VARCHAR(256) Autonomous system (AS) name.

IPv4
†† IPv6

Database Setup

Below are the steps to set up the database for both IPv4 and IPv6 data.

Create Database
CREATE DATABASE ip2location;
USE ip2location;
CREATE TABLE `ip2location_asn`(
	`ip_from` INT(10) UNSIGNED,
	`ip_to` INT(10) UNSIGNED,
	`cidr` VARCHAR(43),
	`asn` VARCHAR(10),
	`as` VARCHAR(256),
	INDEX `idx_ip_from` (`ip_from`),
	INDEX `idx_ip_to` (`ip_to`),
	INDEX `idx_ip_from_to` (`ip_from`, `ip_to`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_bin;
Import Database
LOAD DATA LOCAL
	INFILE 'IP2LOCATION-LITE-ASN.CSV'
INTO TABLE
	`ip2location_asn`
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\r\n'
IGNORE 0 LINES;
Create Database
CREATE DATABASE ip2location
GO

USE ip2location
GO

CREATE TABLE [ip2location].[dbo].[ip2location_asn](
	[ip_from] bigint NOT NULL,
	[ip_to] bigint NOT NULL,
	[cidr] nvarchar(43) NOT NULL,
	[asn] nvarchar(10) NOT NULL,
	[as] nvarchar(256) NOT NULL
) ON [PRIMARY]
GO

CREATE CLUSTERED INDEX [ip_to] ON [ip2location].[dbo].[ip2location_asn]([ip_to]) ON [PRIMARY]
GO
Import Database
BULK INSERT [ip2location].[dbo].[ip2location_asn]
FROM '{PATH TO IP2LOCATION-LITE-ASN.CSV}'
WITH
(
	FORMATFILE = '{PATH TO ASN.FMT}'
)
GO

NOTE: You will need to copy the FMT code below and save it as a file named ASN.FMT on your computer.
