无聊上网，找到一个新的DNS服务器，去年就有了的，据说能有效地抑制3.31号的美国黑客宣称的要瘫痪全球网络的行动。。。
不知道真假，不过测试上网的速度还是不错的
我的电脑原来是自动获取的DNS，打开人人网很慢很慢，开始以为是安装的防火墙跟杀软有问题，而后卸载以后还是出现这个情况，也同时的问了问其他的同学，都表示登陆人人网很慢。。。。所以，就试了下这个新的DNS服务器。。。效果如下：
>ping www.renren.com

前三个是在新的DNS下ping www.renren.com得到的结果，Average time一般是在42ms或者43ms左右
后三个是在自动获取DNS下ping www.renren.com得到的结果，Average time一般是在180ms左右
结果显而易见...
我还特意的测试了下其他的网站，包括谷歌的，发现速度是有些提升...好吧那就用这个吧，感兴趣的也可以试试
新的DNS：114.114.114.114 或者114.114.115.115（填在备用那里就好）
