You may have heard sayings like "If it is broken, it is probably a DNS problem. And if it isn't DNS, it is still a DNS problem". Or "Everything that happens on your network is reflected in DNS.". DNS is a great protocol, sometimes shamed for things it can't help itself with, and sometimes forgotten (if it works well). One of the amazing things I find about DNS is all its little nuances and how it all "fits together". I planned this video series a couple months ago, and figured that this would be easy. I know DNS... but each time I look at DNS, I learn something new, so it has taken a while to get the first episodes together, and today I am releasing the first one. No fixed schedule on when they will be released (weekly?... if DNS doesn't prevent me to post them). No fixed end... not done yet considering topics and ideas.

You can find the first episode here: https://www.youtube.com/watch?v=b8-f-vvygU4
