Video: How to Setup Google DNS on your Computer
Like OpenDNS, Google today launched their own public DNS service that they say will make your web-surfing experience “faster, safer and more reliable.”
If you want to access a site (say example.com) from your browser, your computer needs the IP address of the web server that is hosting that domain. The computer will then query a public DNS server to find the IP address of the site example.com.
This DNS server is generally maintained by your ISP but now you can instruct your computer (or wireless router) to use Google’s DNS server instead of your ISP’s DNS server. Google says their Public DNS Servers are hosted in data centers worldwide, and they use anycast routing to send users to the geographically closest data center.
If you are keen on making the switch to Google DNS, here’re the steps involved for Windows XP, Vista and Windows 7.

Select Internet Protocol Version 4 (TCP/IPv4), followed by Properties and them replace the IP addresses of your Preferred DNS server and Alternate DNS server with the IP addresses of the Google DNS servers which are 18.104.22.168 and 22.214.171.124 - the order doesn’t matter.

In the above videos, I have changed settings for an Ethernet (LAN) connection but the steps are similar for Wireless networks as well.
In case you would like to setup Google DNS at the router level, open your router dashboard (e.g., http://192.168.1.1) and put the Google DNS server addresses (126.96.36.199 and 188.8.131.52) as your DNS server settings and apply.
How to Test Google DNS Servers
Open your command prompt and clear your DNS cache using the command
ipconfig /flushdns. Then do a
nslookup for any web address and you should see 1e100.net with 184.108.40.206 as the IP address for the DNS resolver.
