I promise it wasn't meant as elitism. If someone were to think that knowing DNS makes them elite... well, that's unfortunate.
My point was much simpler, know when to outsource it to a third party or someone you hire, if you don't know the details of what you're getting into. Especially when it's something as fundamental as the ONLY entrance point people have to your business's online presence.
Elitism is in the eye of the beholder, I guess.
