ip2region's Introduction

ip2region - 最自由的ip地址查询库,ip到地区的映射库,提供Binary,B树和纯内存三种查询算法,妈妈再也不用担心我的ip地址定位。

1. 99.9%准确率,定时更新:

数据聚合了一些知名ip到地名查询提供商的数据,这些是他们官方的的准确率,经测试着实比纯真啥的准确多了。
每次聚合一下数据需要1-2天,会不定时更新。

2. 标准化的数据格式:

每条ip数据段都固定了格式:城市Id|国家|区域|省份|城市|ISP

只有**的数据精确到了城市,其他国家只能定位到国家,后前的选项全部是0,已经包含了全部你能查到的大大小小的国家。 (请忽略前面的城市Id,个人项目需求)

3. 体积小:

生成的数据库文件ip2region.db只有1.5M(1.2版本前是3.5M)

4. 多查询客户端的支持,0.0x毫秒级别的查询

已经集成的客户端有:java, php, c, python,nodejs,php扩展(支持linux, php5, php7版本已支持)。

提供了两种查询算法,响应时间如下:
客户端/binary算法/b-tree算法/Memory算法:
java/0.x毫秒/0.x毫秒/0.1x毫秒 (使用RandomAccessFile)
php/0.x毫秒/0.1x毫秒/0.1x毫秒
c/0.0x毫秒/0.0x毫秒/0.00x毫秒(b-tree算法基本稳定在0.02x毫秒级别)
python/0.x毫秒/0.1x毫秒/未知

任何客户端b-tree都比binary算法快,当然Memory算法固然是最快的!

5. 测试程序: java:

cd binding/java
ant all
java -jar ip2region-{version}.jar ./data/ip2region.db

php:

php binding/php/testSearcher ./data/ip2region.db

c:

cd binding/c/
gcc -g -O2 testSearcher.c ip2region.c
./a.out ../../data/ip2region.db

python:

python binding/python/testSearcher ./data/ip2region.db

均会看到如下界面:

initializing  B-tree ... 
+----------------------------------+
| ip2region test script            |
| Author: [email protected]  |
| Type 'quit' to exit program      |
+----------------------------------+
p2region>> 101.105.35.57
2163|**|华南|广东省|深圳市|鹏博士 in 0.02295 millseconds

输入ip地址开始测试,第一次会稍微有点慢,在运行命令后面接入binary,memory来尝试其他算法,建议使用b-tree算法,速度和并发需求的可以使用memory算法。

具体集成请参考不同客户端的测试源码。
