In doesn’t seem like a day goes by that Google hasn’t been making announcements about new services and features. This time Google is offering DNS service for free. What does this mean for those who choose to use the service? Hopefully a safer and more reliable browsing experience. On its Web site, Google states:

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.

There is also this [the bold red emphasis is mine]:

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

Make sure that you also write down your current server setting just in case you need to revert back to your old system. Google has provided a .pdf document that walks you through the steps to setup their DNS service.

Comments welcome.
