互联网有很多接口可以实现通过ip查询到具体的位置，如下：通过淘宝IP地址库获取IP位置
新浪的接口 ：
返回值 var remote_ip_info = {“ret”:1,”start”:”218.192.0.0”,”end”:”218.192.7.255”,”country”:”\u4e2d\u56fd”,”province”:”\u5e7f\u4e1c”,”city”:”\u5e7f\u5dde”,”district”:”“,”isp”:”\u6559\u80b2\u7f51”,”type”:”\u5b66\u6821”,”desc”:”\u5e7f\u5dde\u5927\u5b66\u7eba\u7ec7\u670d\u88c5\u5b66\u9662”}; 通过jqry 获取相应的数据 $.getScript(‘数据接口’,function(){ //新浪：remote_ip_info.country })腾讯IP分享计划的地址获取IP所在地：
用java调用淘宝ip查询接口查询地域的一个java实例：
