DNS overload?

I agree with Dan Kaminsky (and therefore disagree with Paul Mockapetris): Vista will not overload the Internet's DNS architecture.

What it may do, is overload your internal DNS architecutre, if your internal architecture is already running near capacity. It all falls back to architecture planning.

For those that need to "learn by doing": put four emergency spares (tires) on your car and then get out on the interstate and try to drive 500 miles while maintaining the speed limit. (Hint: I-95 works best. The speed limit is 70 in places and you'll quickly earn the enmity of those drives behind.)
