OpenDNS is a fantastic free service for filtering phishing sites, adult sites, and pretty much anything else you can think of.  It also does perform DNS lookups faster than any site that I have seen to date.  It is easy to admin and you can control your entire enterprise with this service.  Best of all it’s free.

One feature I love about OpenDNS is how I can globally set shortcuts to use a short word for a long address. There’s nothing to install and it works how you want it to, no matter which browser you’re using. Add, remove or change your OpenDNS shortcuts at any time.

OpenDNS provides you with the tools to see what’s happening on your network, coupled with the tools to take action. For example, discover that myspace.com is the most frequently visited site on your network, and then block it with a single click.
