该算法将一个IP地址,并将返回的国家(如美国、城市、国家)的IP地址是。这将自动确定哪些WHOIS查询并返回服务器的信息发现。这段代码将工作大约95 的IP地址。有太多的格式来匹配100 。这个应用程序是一个很好的工具来跟踪你的网站的访问者来自。请投票和评论将不胜感激!如果你借我的代码,分享你的!必须有SQL Server或MSDE。 SQL数据库创建脚本包含。-This algorithm will take an IP Address and will return the country (if us, City, state, country) where the IP Address is from.

There are just too many formats to match 100 . This application is a nice utility to track where the visitors to your website are coming from. Please Vote and any comments will be greatly appreciated! If you borrow my code, share yours! Must have SQL Server or MSDE. SQL DB Creation scr ipt Included.
