Well, isn't that interesting. Google just released a DNS service.
I've been an OpenDNS user for a while now, but this is interesting, so I decided to try it. It's not really configurable like OpenDNS is, but for the average user that doesn't matter. But will the average user realize the benefits of such a service? Will the average user even care? Not likely. That's what Google needs to work on if they want to make Google Public DNS catch on.
There's also, you know, all that extra data going through Google. I know some people that wouldn't like that idea.
