IP Address test
The test has found that the IP address used by your computer cannot be scanned. This commonly occurs because of a firewall program on your computer and/or you are connected to the Internet through a proxy-server or your ISP uses Network Address Translation (NAT) to share IP addresses.
This means the test cannot check your system as the results of the testing would be incorrect.
通过代理服务器连接网络的情况下，这种测试结果不准确。这个网站还是比较诚实的。
有一些类似的测试网站完全不提这一点，结果测试出来的根本就是代理服务器的状况，而不是终端机的状况。
