这篇文章中的内容是来源于去年我用美国的vps搭建博客的初始阶段，那是有很多恶意访问，我就根据access log中的源ip来进行了很多统计，同时我也将访问量最高的恶意访问的源ip拿来查询其地理位置信息。所以，我就用到了根据ip查询地理位置信息的一些东西，现在将这方面积累的一点东西共享出来。
根据ip查询所在地、运营商等信息的一些api如下（根据我有限的一点经验）：1. 淘宝的api（推荐）：http://ip.taobao.com/service/getipinfo.php?ip=110.84.0.1292. 国外freegeoip.net（推荐）：http://freegeoip.net/json/110.84.0.129 这个还提供了经纬度信息（但不一定准）3. 新浪的api：http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=110.84.0.1294. 腾讯的网页查询：http://ip.qq.com/cgi-bin/searchip?searchip1=110.84.0.1295. ip.cn的网页：http://www.ip.cn/index.php?ip=110.84.0.1296. ip-api.com： http://ip-api.com/json/110.84.0.129 （看起来挺不错的，貌似直接返回中文城市信息，文档在 ip-api.com/docs/api:json）7. http://www.locatorhq.com/ip-to-location-api/documentation.php （这个要注册才能使用，还没用过呢）
（第2个freegeoip.net的网站和ip数据的生成，代码在：https://github.com/fiorix/freegeoip）
为什么其中第4、5两个是网页查询也推荐了呢？是因为两方面原因，一是它们提供的信息比较准，二是使用了页面信息自动抓取（可能会用到我曾经写过的phantomjs）也容易将其写到程序中成为api。
根据ip查询地理位置信息，我将其写成了一个较为通用的python库（提供了前面提到的1、2、4、5等4种查询方式的api），可以根据ip查询到地域信息和isp信息，具体代码见：https://github.com/smilejay/python/blob/master/py2013/iplocation.py注意其中对ip.cn网页的解析用到了webdriver和phantomjs.
代码如下:
