这套识别程序的数据库是免费IP数据库、IP离线地址库。支持将IP转化为结构化的国家、省、市、县、运营商、地区信息)
0，该数据库识别是离线的。
1，该数据库基于纯真IP库，IP地址纠错相关和最新地址获取请直接去纯真官网，下面有给出地址。
2，纯真IP识别算法来源网络。
3，结构化程序来自我2012年的脑洞。
纯真IP已从03年开始存在多年且一直免费，实属不易。因为数据存储时，并不是结构化的，因此有误差在所难免。这个结构化程序，国内 ip 可以识别出省份，基本可以识别出市。运营商、县数据看运气。
当前版本为3.x（ipv4+ipv6），如需要2.x稳定版请访问 https://github.com/itbdw/ip-database/tree/2.x
目前3.x无缝兼容2.x版本，理论上可直接升级，但需做好验证。
composer require 'itbdw/ip-database' ^3.0
//根据实际情况，基本上用框架（如 Laravel）的话不需要手动引入
//require 'vendor/autoload.php';
use itbdw\Ip\IpLocation;
//0配置使用
echo json_encode(IpLocation::getLocation($ip), JSON_UNESCAPED_UNICODE) . "\n";
//支持自定义文件路径
$qqwry_filepath = '/abspath/qqwry.dat';
$ipv6wry_path = '/abspath/ipv6wry.db';
echo json_encode(IpLocation::getLocation($ip, $qqwry_filepath), JSON_UNESCAPED_UNICODE) . "\n";

这个项目也是多个日夜思考的结果，如果觉得对你有帮助，小手一抖也是感谢的。
