IP2Location™ LITE IP-ASN Database

IP2Location™ LITE IP-ASN 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. A unique ASN is allocated to each AS for use in BGP routing. The data is being collected through routers in monthly basis. It might not be complete, up-to-date and suitable for real-time routing purpose. Please refer to RFC 1771 and RFC 1930 for more information about AS.

CREATE TABLE [ip2location].[dbo].[ip2location_asn](
	[ip_from] float NOT NULL,
	[ip_to] float NOT NULL,
	[cidr] nvarchar(18) NOT NULL,
	[asn] nvarchar(10) NOT NULL,
	[as] nvarchar(256) NOT NULL

CREATE INDEX [ip_from] ON [ip2location].[dbo].[ip2location_asn]([ip_from]) ON [PRIMARY]
GO

CREATE INDEX [ip_to] ON [ip2location].[dbo].[ip2location_asn]([ip_to]) ON [PRIMARY]

NOTE: You will need to copy the FMT code below and save it as a file named ASN.FMT on your computer. The first line of the FMT code indicates the version of bcp. Please change the version as according to your MS-SQL installed.
