Google recently launched a public DNS service which is an experiment in improving both the speed of DNS queries (which are required for all of your web browsing) and the security of the caching and DNS transactions (which is a major problem on the Internet today).
You can get introductory information about their Public DNS here.
When you are ready to set your DNS server configuration to point to the Google Public DNS Servers, you will want to check out this page on Using Google Public DNS.
For those of us who are particularly interested in the security aspects of these google DNS servers, we will want to read the information posted about the Security Benefits.
You all will no doubt want to read about the Privacy Issues , and how Google is addressing them. In short they are promising to only keep personally identifiable information for no more than 48 hours.
May all your holiday DNS queries be fast and secure!
