# 丝袜套头上，紧急备用 https://code.google.com/p/goagent/issues/detail?id=20491
1. SPC Socks Proxy Checker
http://www.socksproxychecker.com/
最可靠, 快慢代表带宽.
玩套的话, 连接网桥未必就快, 但是上套就快了. 北欧国家袜子连接网桥最容易.

2. EPS Elite Proxy Switcher
http://www.eliteproxyswitcher.com/
老牌, 名牌

3. GPTool
http://www.gatherproxy.com/proxychecker
检测不大可靠, 不过可以自己收集各网站的免费袜子, 并且自动合并重复.

在线检测
http://sockslist.net/check
立马检测到的, 就是大带宽.

手动
找那些人家收集检测过的袜子列表, 一般都是60,70个这样发布. 每天发布六七次.

用户
不想切换袜子, 只想稳定的话,

俄国乌克兰最多稳定的免费袜子, 带宽一般. 
亚洲的最好是澳新印尼, 其次韩日台,
中东,伊朗也门也不错, 不过亚洲带宽更小. 
欧洲稳定的袜子只有那些小国家. 
美加都很多而且稳定, 不过跟SS一样连接比较慢.

中南美, 非洲的基本无法用.

参考http://compnetworking.about.com/od/traceipaddresses/f/google-ip-address.htm
Question: What Is the IP Address of Google?

Web site administrators like to know the IP addresses used by Google when it is spidering. You can also sometimes use Google's IP address to reach the site www.google.com if the domain cannot be contacted by its name.

Answer:

The following IP address ranges belong to Google:

    64.233.160.0 - 64.233.191.255
    66.102.0.0 - 66.102.15.255
    66.249.64.0 - 66.249.95.255
    72.14.192.0 - 72.14.255.255
    74.125.0.0 - 74.125.255.255
    209.85.128.0 - 209.85.255.255
    216.239.32.0 - 216.239.63.255

Like many popular Web sites, Google utilizes multiple Internet servers to handle incoming requests to its Web site. Instead of entering http://www.google.com/ into the browser, a person can enter http:// followed by one of the above addresses, for example:

    http://74.125.224.72/ 

Only certain addresses from Google's pool will work depending on the physical location of the browser.

Besides serving www.google.com, some of the Google's IP addresses above are utilized by its Googlebot Web crawlers.
