I did not know this, but I think this is very, very cool.
I have OpenDNS resolution baked in to my MacBook Pro so that I use them no matter where I am, and I also have them set up to do DNS from my router at home as well, so any computer on my home network automatically gets the benefits of OpenDNS.
As if it wasn’t awesome enough that they’re doing this sort of aggressive security, they’re fast as hell. I highly recommend using them, even on just their free plans.
