How to Configure Google Public DNS?

Post by Admin on 9th December 2009, 4:23 pm

The Google Public DNS IP addresses required for DNS settings are as:
8.8.8.8
8.8.4.4


Any of the about IP address can be chosen as a primary address, and the other as a secondary address.

Open the Control Panel, click on Network and Internet. Now, click on Network and Sharing Center, and then select “Change adapter settings”.

In the next screen, select the connection that you want to configure for Google Public DNS.

If you want to change the settings for an Ethernet connection, right-click Local Area Connection, and click Properties. Or else, if you want to change the settings for a wireless connection, right-click the icon/link for the wireless network connection that you’re using, and then click Properties.

The Local Area Connection Properties dialog box will appear on the screen. Select the Networking tab. Now, under “This connection uses the following items”, click on the “Internet Protocol Version 4 (TCP/IPv4)” and then click on the Properties button.

A new dialog box with the title of “Internet Protocol Version 4 (TCP/IPv4) Properties” will appear on the screen. Now, select the radio box “Use the following DNS Server addresses”, and in the Preferred DNS Server text box, enter “8.8.8.8” and in the Alternate DNS Server, enter “8.8.4.4”.

Now, click OK on this dialog box to close it.

Click on Close button of the Local Area Connection Properties dialog box to close it.

Testing the changed DNS settings:
Once you’ve made the changes to your DNS settings to use Google Public DNS, you must test it to check whether the Google DNS resolver is working. For its confirmation just follows a very short and simple step: In the address bar of your browser, type a web address http://www.google.com/. If it resolves correctly and takes you to that website, bookmark the page, and then try to access the same web address again from the bookmark. If both of these tests work properly and the desired website opens properly, then it means that Google Public DNS is working correctly. If these tests do not work properly, then you must configure it again from the start.

How to switch back to the old DNS settings?
In some cases, it may also be possible to switch back to old DNS settings by using the automatic settings. For doing so, go back to the window in which you had specified the Google IP addresses, and select the option to enable obtaining DNS server addresses automatically, and/or delete the Google IP addresses. This will slip back your settings to using your ISP’s default servers.
