可以看出，从这个网站上直接看到的是“访问国内网站”时使用的 IP 地址（对比下面的）；

ip111.cn

网址：http://www.ip111.cn/

效果图

原理

• 访问 http://45.32.164.128/ip.php 来获取访问未被墙国外网站（自己部署的一个简单服务）时使用的 IP 地址

• 访问 http://ip111cn.appspot.com/ 来获取访问被墙国外网站（谷歌/Facebook/Twitter）时所使用的 IP 地址

问题

• “从国内测试”栏中显示的 IP 地址怎么获得的没搞清楚

What can we know about you?

Did you know that anyone can locate your ISP-assigned public IP address with a 5km-radius accuracy? We can also discover much more about your Internet connection. By the moment you browse this page, we determined your device's public IP address and performed a geolocation lookup over your connection. You can compare this data to what you expect from your connection, especially if you're using any Proxy or VPN solution.

Results

In addition to the precise Google Maps geo positioning powered by MaxMind technology, a table synthesises the geo-data gathered for your IP address.

This tool provides you a precision down to 5km on the GPS coordinates (latitude, longitude) and administrative location (continent, country, region, postal code, city) of that IP.

We complete this report with other useful data about your hostname and timezone (date and time).

This IP Locator gives you the advantage of knowing much more about other party can find about you on the Web.
