在网上搜索了一下，获取客户端的访问IP，这个会。
但是如何查询出该IP的归属地如何实现？
网上提供了IP地址归属地查询接口，有返回json的，有返回xml的，有返回文本的。
不知道怎么使用。写的都比较简单。
能否运用到asp里面？能否提供一个比较完整的查询接口，可以查询归属地、ISP等信息的。
然后插入到数据库里。
能否举个详细的例子。谢谢。

这个很简单的吧
比如用百度的查询归属地：
Function getHTTPPage(Path)
t = GetBody(Path)
getHTTPPage=BytesToBstr(t,"GB2312")
End function
Function Newstring(wstr,strng)
Newstring=Instr(lcase(wstr),lcase(strng))
if Newstring<=0 then Newstring=Len(wstr)
End Function
Function BytesToBstr(body,Cset)
dim objstream
set objstream = Server.CreateObject("adodb.stream")
objstream.Type = 1
objstream.Mode =3
objstream.Open
objstream.Write body
objstream.Position = 0
objstream.Type = 2
objstream.Charset = Cset
BytesToBstr = objstream.ReadText
objstream.Close
set objstream = nothing
End Function
Function GetBody(url)
on error resume next
Set Retrieval = CreateObject("Microsoft.XMLHTTP")
With Retrieval
.Open "Get", url, False, "", ""
.Send
GetBody = .ResponseBody
End With
Set Retrieval = Nothing
End Function
url = "http://open.baidu.com/ipsearch/s?wd=$ip&tn=baiduip"
wstr=getHTTPPage(url)
这样把获取到的内容使用正则获取一下就可以了
