In December 2009, Google launched a free, global Domain Name System (DNS) service. Google Public DNS servers are 8.8.8.8 and 8.8.4.4 for use as alternative to your current DNS servers.
How to set-up Google DNS on Windows 7
- Go to Control Panel.
- Click Network and Internet > Network and Sharing Center > Change adapter settings.
- Select the connection for which you want to configure Google Public DNS. For example:
- To change the settings for an Ethernet connection, right-click Local Area Connection, and click Properties.
- To change the settings for a wireless connection, right-click Wireless Network Connection, and click Properties.
- In the Networking tab, click Internet Protocol Version 4 (TCP/IPv4), and then click Properties.
- 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.
- Click OK.
- 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.
- Replace those addresses with the IP addresses of the Google DNS servers: 8.8.8.8 and 8.8.4.4.
- Restart the connection you selected in step 3.
- Test that your setup is working correctly:
- From your browser, type in a webpage, such as http://www.coolbuster.net. If it resolves correctly, bookmark the page, and try accessing the page from the bookmark. If this test works, everything is working correctly. If not, go back to step 2.
- Repeat the procedure for additional network connections you want to change.
