询问关于根据IP查询某个IP来自哪里的问题

我下载了动网的IP地址库，并写了如下代码，但查询不到。。请大家帮忙◎
<% ip=request.servervariables("remote_addr")
response.write ip
response.write "<br>"
ip=replace(ip,".","")
response.write ip
response.write "<br>"
Set rs = Server.CreateObject("ADODB.Recordset")
sql ="select * from dv_address where ip1<="&ip&" and ip2>="&ip&" "
rs.open sql,Conn,1,1
response.write rs.recordcount
%>
