google的免费dns服务器

google推出了自己的免费dns服务器,以供公众使用。服务器地址是:

dns1: 8.8.8.8

dns2: 8.8.4.4

我在我的机器上测试了一下:

$ host -a g.cn 8.8.8.8
Trying “g.cn”
Using domain server:
Name: 8.8.8.8
Address: 8.8.8.8#53
Aliases:

google的免费dns服务器》的相关评论

  1. 实在想不出来使用这个DNS有什么必要。

    真的能翻墙么?不能。
    真的速度快么?导致访问的时候CDN无法判断用户来源,把你当成美国用户服务,你速度是快了还是慢了?

  2. Are you saying Master P is good at rapping? Aren’t all of his songs simply grunts? Isn’t his hit song “Ugh, Na Na Na Na?” I have to admit, though, that I never saw his movie “I Got the Hookup, Ugh!”I agree that Ludacris was good in &#.202;Crash8” In fact, he was the only good part of that awful, ridiculously overrated movie.
