The article is talking about the inherent vulnerability to man-in-the-middle attacks (setting up hostile DNS servers) when using unencryted DNS. It doesn't talk about how secure DNS is implemented in a software basis on Macs.
Most likely, the 208.67.222.222 server run by OpenDNS isn't set up for secure DNS queries; only the one at 208.67.220.220 is.
1. I guess we'll find out sometime down the road, and hopefully not the hard way.
2. Aaah... The two sets of numbers represent two different servers. (Did I miss something incredibly obvious?) I just noticed that when I toggle "Crypt" off the second set of numbers appears.
Again... Thanks.
