Moving from OpenDNS to Google DNS

It is best to use a DNS resolution service to avoid targeted attacks on your machine esp if you use the browser a lot. and it is quite fast!! Takes 2 minutes to set it up even for non geeks

I was getting slower browsing speeds on OpenDNS http://www.opendns.com/

so I switched to Google DNS (though I am not sure how people in Iran and China – who have a much greater need for DNS verification services will get secure resolution of DNS)

What is Google Public DNS?

Google Public DNS is a free, global Domain Name System (DNS) resolution service, that you can use as an alternative to your current DNS provider.

To try it out:

Configure your network settings to use the IP addresses 8.8.8.8 and 8.8.4.4 as your DNS servers or
Read our configuration instructions.

^New! For IPv6 addresses, see our configuration instructions.

If you decide to try Google Public DNS, your client programs will perform all DNS lookups using Google Public DNS.

Why does DNS matter?

The DNS protocol is an important part of the web’s infrastructure, serving as the Internet’s phone book: every time you visit a website, your computer performs a DNS lookup. Complex pages often require multiple DNS lookups before they start loading, so your computer may be performing hundreds of lookups a day.
