首先,是前人写的ASP查询纯真IP的类，请保存为cz.asp
需要一个ip数据库，把cz.asp,serach.asp和cz.dat数据库放在一起。

下面是查询代码,请保存为search.asp
<!--#include file="cz.asp" -->
<%
Dim IP
ip=request.querystring("ip")
if trim(ip)="" then
IP=Request.ServerVariables("REMOTE_ADDR")
elseif ubound(split(trim(ip),"."))<>3 then
IP=Request.ServerVariables("REMOTE_ADDR") 'ip地址
end if
IPAdd=Look_Ip("cz.dat",IP) '这里注意,数据库文件名是cz.dat
response.write IPAdd

'给你一个获得IP的函数，如果想得到地理位置，需要一个IP数据库，类似QQ显IP的数据库，暂时没有。
Function GetIP()
If Request.ServerVariables("HTTP_X_FORWARDED_FOR") = "" OR InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), "unknown") > 0 Then
GetIP = Request.ServerVariables("REMOTE_ADDR")
ElseIf InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ",") > 0 Then

ElseIf InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ";") > 0 Then
GetIP = Mid(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), 1, InStr(Request.ServerVariables("HTTP_X_FORWARDED_FOR"), ";")-1)

这种显示你需要有ip地址与地理位置对应的地址库才可以。
