Using Google Public DNS

google推出的这个DNS服务并不是跟opendns抢生意,从目前看来它也不具备opendns的强大管理功能。

具体对比将在实名博上做讨论,这边只是记录一下google推出的各种系统平台上的dns设置方法。

~~~~~~~~~~~~~~~~~~~~~~~~~~

Configuring your network settings to use Google Public DNS

When you use Google Public DNS, you are changing your DNS “switchboard” operator from your ISP to Google Public DNS.

In most cases, the IP addresses used by your ISP’s domain name servers are automatically set by your ISP via the Dynamic Host Configuration Protocol (DHCP). To use Google Public DNS, you need to explicitly change the DNS settings in your operating system or device to use the Google Public DNS IP addresses. The procedure for changing your DNS settings varies according to operating system and version (Windows, Mac or Linux) or the device (computer, phone, or router). We give general procedures here that might not apply for your OS or device; please consult your vendor documentation for authoritative information.

Note: We recommend that only users who are proficient with configuring operating system settings make these changes.

Important: Before you start

Before you change your DNS settings to use Google Public DNS, be sure to write down the current server addresses or settings on a piece of paper. It is very important that you keep these numbers for backup purposes, in case you need to revert to them at any time.

After changing your settings, if you encounter a problem and cannot connect to the Internet, please call our support numbers for troubleshooting instructions.

We also recommend that you download this page and print it, in the event that you encounter a problem and need to refer to these instructions.

Google Public DNS telephone support

* 877-590-4367 in the U.S.

* 770-200-1201 outside the U.S.

Google Public DNS IP addresses

The Google Public DNS IP addresses are as follows:

* 8.8.8.8

* 8.8.4.4

You can use either number as your primary or secondary DNS server. You can specify both numbers, but do not specify one number as both primary and secondary.

Changing your DNS servers settings

Because the instructions differ between different versions/releases of each operating system, we only give one version as an example. If you need specific instructions for your operating system/version, please consult your vendor’s documentation. You may also find answers on our user group.

Many systems allow you to specify multiple DNS servers, to be contacted in a priority order. In the following instructions, we provide steps to specify only the Google Public DNS servers as the primary and secondary servers, to ensure that your setup will correctly use Google Public DNS in all cases.

Note: Depending on your network setup, you may need administrator/root privileges to change these settings.

Microsoft Windows

DNS settings are specified in the TCP/IP Properties window for the selected network connection.

Example: Changing DNS server settings on Microsoft Windows Vista

加工号付费原则

因 号码开通时以年计费,如果在使用过程中加工号,所付费用为剩下月份数费用已便和号码开通时间对齐。譬如,5月1日开通,10月1日加工号,赠加的工号需付 费7个月,统一至第二年5月1日到期;如果开通和加工号时间天数不一致,按照相差的日期近似到整月,譬如,5月1日开通,10月10日加工号,加的工号需 付费7个月,如果10月16日加工号,加的工号付费6个月。

注:2009年10月15日开始使用此资费标准。此前开通的客户,可享受一年老资费续费的优惠。
