I've recently found a very accurate free ip database provided by MaxMind.
I have tried some methods to import this csv data into my Sql Server database, but what I have found that either the example was broken or wasn't complete (files were missing from the script download).
So I started to digg into the issue and found a simple and fast way of importing the 2 csv's into my sql server database.- First, you need to edit the 2 csv files and remove all quotes ("). Since the files are fairly large, use a smart editor (I used Notepad2).
- Run the following code. Don't forget to replace the paths to the files with your own.
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = 'GeoIP')BEGIN
DROP TABLE GeoIP
END
CREATE TABLE GeoIP (
	startIpNum bigint,
	endIpNum bigint,
	locId  bigint
)
-- first remove ALL quotes from csv to import
BULK INSERT GeoIP FROM 'your\path\to\GeoLiteCity-Blocks.csv' WITH (FIRSTROW = 3, FIELDTERMINATOR=',', ROWTERMINATOR = '0x0a')
CREATE CLUSTERED INDEX Geo_IP_Look
ON GeoIP
([StartIpNum], [endIpNum],  [locId])
   
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = 'GeoLoc')BEGIN
DROP TABLE GeoLoc
END
CREATE TABLE GeoLoc (
	 locId bigint,
	 country nvarchar(2),
	 region nvarchar(3),
	 city nvarchar(255),
	 postalCode nvarchar(10),
	 latitude nvarchar(15),
	 longitude nvarchar(15),
	 metroCode nvarchar(15),
	 areaCode nvarchar(15)
)
BULK INSERT GeoLoc FROM 'your\path\to\GeoLiteCity-Location.csv' WITH (FIRSTROW = 3, FIELDTERMINATOR=',', ROWTERMINATOR = '0x0a')  
CREATE CLUSTERED INDEX Geo_Info_Look
ON GeoLoc
([locId], [country], [region], [city], [latitude], [longitude])
I tested the code on my SQL Server 2008 R2 db, and it all worked OK. 
Update: you might want to remove the headers from the maxmind csv's.
