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: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 33253 ;; flags: qr rd ra; QUERY: 1, ANSWER: 11, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;g.cn.
