见识google dns的暴强Ip地址

What is Google Public DNS?

Google Public DNS is a free, global Domain Name System (DNS) resolution service, that you can use as an alternative to your current DNS provider.

To try it out:

Configure your network settings to use the IP addresses 8.8.8.8 and 8.8.4.4 as your DNS servers

ping了一下，这2个ip的响应时间大致在70毫秒上下，sina和163分别为15毫秒-40毫秒.

以前家里路由器一直用opendns,每次换回电信dns后再改回去总得查询一下，opendns的地址太难记了。呵呵。google dns 的ip 相信大家不会再遗忘了。

换好dns后再ping各大网站，有些响应时间有提升，sina和163响应时间下降了:)
