maybe you can add this into your default.asp file
<!<span class="code-comment">#include file="GeoIP.asp"--></span>
<%
Dim oGeoIP,strErrMsg
Dim strIP,strCountryName,strCountryCode
Set oGeoIP = New CountryLookup
oGeoIP.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 If
Set oGeoIP = Nothing
%>
Download the GeoIP.dat database from MaxMind
http://www.maxmind.com/app/standard
Put GeoIP.asp, and GeoIP.dat in a catalog on your web server.
been done this before with php
