要向上YouTube，需要在hosts文件的最后添加以下几行：

203.208.39.104 youtube.com
203.208.39.104 www.youtube.com
203.208.33.100 gdata.youtube.com
74.125.91.118 upload.youtube.com
74.125.93.102 insight.youtube.com
64.233.161.104 help.youtube.com

保存即可。想要上Twitter的话，需要在hosts文件的最后添加以下几行：

128.121.146.228 twitter.com
128.121.146.228 www.twitter.com
128.121.146.101 assets0.twitter.com

65.74.185.41 twitter.zendesk.com
65.74.185.41 help.twitter.com

注意此时需要使用https加密的安全连接，Twitter的地址应该是https://twitter.com。要想上facebook的话，需要在hosts文件最后添加以下几行：

124.40.42.105 www.facebook.com
69.63.180.173 login.facebook.com
69.192.34.110 s-static.ak.facebook.com
69.63.176.69 secure-profile.facebook.com
69.63.176.59 secure-media-sf2p.facebook.com
69.63.178.13 ssl.facebook.com
96.6.122.57 profile.ak.facebook.com
64.211.21.152 b.static.ak.facebook.com

同样，facebook也需要https加密的安全连接，此时的facebook地址为https://www.facebook.com。注意，facebook的https证书没有被验证，浏览器会弹出提示。Firefox的话添加例外即可，Opera的话通过即可。

现在修改过hosts文件之后就能上YouTube，Twitter，facebook了。如果你觉得我说得好请把本文推荐给你的朋友，大家一起来推倒这堵墙。
