很奇怪，我们可以访问www.wordpress.com的网站，但是一旦建立了博客，用xxx.wordpress.com想访问自己的blog却是找不到服务器了。
其实我们ping下www.wordpress.com和xxx.wordpress.com就能发现不同的结果.
1.
C:Documents and SettingsAdministrator>ping www.wordpress.com
wordpress.com
2.Pinging wordpress.com [76.74.254.126] with 32bytes of data:

而我们ping xxx.wordpress.com的结果却是
C:Documents and SettingsAdministrator>ping zauc.
2.Pinging lb.wordpress.com [72.233.2.58] with 32bytes of data:
Pinging lb.
72.233
2.58
3.Request timed out.
Request timed out.
4.Request timed out.
5.Request timed out.
6.Request timed out.
所以我们可以很容易发现自己单独域名的博客会全部会转到lb.wordpress.com这个域名下。但是这个IP明显是被GFW给屏蔽掉了。但是看这个域名就知道这个只是前端负载均衡设备的IP。但是其实一般真实设备的IP一般都是在这个真实IP的周围。

找到可以PING通的IP了，windows系统指需要用记事本修改以下文件，指定下Hosts就可以了。
C:\WINDOWS\system
32\
drivers\etc\hosts
2.72.233.2.57 zauc.wordpress.com
zauc.
那以后不需要使用代理服务器来访问自己的BLOG了。
