I use OpenDNS as my DNS server. I think that it is the fastest and most secure around. However, I feel that there is one problem. The instructions on their website ( www.opendns.com ) on how to set it up aren't very clear if you are not a computer geek. I love OpenDNS sooo much that I made this little script which will change the DNS server your computer goes to. If you would like to use OpenDNS as your DNS server; download and run this batch file on every computer in your house. If you sign up ( FOR FREE ) with them you can have many more great features such as blocking websites do to content and by keywords etc..

Here is what they say:
