昨天，Google发布了Google DNS服务，提供主副DNS服务器地址：
8.8.8.8
8.8.4.4

非常吉利的数字！

为什么你需要Google的DNS呢？国内的DNS提供商（譬如中国电信）可能会篡改某些DNS（譬如，对于本来不存在的域名，自动跳转到114的广告页面上），从而存在安全隐患。

Google的DNS承诺：
1. 更快速的域名定位查找服务
2. 提供更好的安全性
3. 绝无重定向

Example: Changing DNS server settings on Microsoft Windows Vista

1. Go the Control Panel.
2. Click Network and Internet, then Network and Sharing Center, then Manage network connections.

   • To change the settings for a wireless connection, right-click Wireless Network Connection, and click Properties.

   If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

4. Select the Networking tab. Under This connection uses the following items, click Internet Protocol Version 4 (TCP/IPv4), and then click Properties.
5. Click Advanced and select the DNS tab. If there are any DNS server IP addresses listed there, write them down for future reference, and remove them from this window.
6. Click OK.
7. Select Use the following DNS server addresses. If there are any IP addresses listed in the Preferred DNS server or Alternate DNS server, write them down for future reference.
8. Replace those addresses with the IP addresses of the Google DNS servers:?8.8.8.8 and 8.8.4.4.
9. Restart the connection you selected in step 3.
10. Test that your setup is working correctly; see Testing your new settings below.
11. Repeat the procedure for additional network connections you want to change.
