Introduction

With GeoIP you can detect where your visitors are coming from. You can use this information to deliver personalized information (see image below), reducing credit card fraud, analyzing web server logs (I use it for SNIFF), target banner ads, .... (see Solutions at MaxMind - http://www.maxmind.com/)

Note

If you can install a component on your web server, you should download the GeoIP component from MaxMind . I wrote GeoIP.asp since my provider doesn't allow me to install components.

Prerequisite

You need the GeoIP database - http://www.maxmind.com/app/free, and you need ADO 2.5 or later since GeoIP.asp uses the ADO Stream object to read the GeoIP database.

Installation

Download the GeoIP.dat database from MaxMind http://www.maxmind.com/app/free Put GeoIP.asp, example.asp and GeoIP.dat in a catalog on your web server. Test the installation by accessing the example.asp page http://yourserver/path/example.asp

Methods and Properties

GeoIP.asp exposes these public methods and properties
Properties:
GeoIPDataBase - Sets the path and filename to GeoIP.dat ErrNum - Returns the error number (if <> 0, there's an error)
Methods: lookupCountryName - Find an IP's country name example: strCountryName = oGeoIP.lookupCountryName(strIP) lookupCountryCode - Find an IP's country code example: strCountryCode = oGeoIP.lookupCountryCode(strIP)

Using the code

It's rather simple to use this code:

Select All Code <!--#include file="GeoIP.asp"--><%Dim oGeoIP,strErrMsgDim strIP,strCountryName,strCountryCodeSet oGeoIP = New CountryLookupoGeoIP.GeoIPDataBase = Server.MapPath("GeoIP.dat")If oGeoIP.ErrNum(strErrMsg) <> 0 Then    Response.Write(strErrMsg)Else    strIP = request.ServerVariables("REMOTE_ADDR")    strCountryName = oGeoIP.lookupCountryName(strIP)    strCountryCode = oGeoIP.lookupCountryCode(strIP)End IfSet oGeoIP = Nothing%>
