DNS is 37 years old, still today, one of the pillars of the modern Internet. Everything you do from deploying your app to twitter uses it. Yet, it's a black box for many of us. This talk covers the basics from resolvers to ICANN and the IETF we will a bird view and zoom into the exciting details.

This talk was born from an open space session I did at a local conference. I learned that it's a topic often touched on, but people often have many questions about it. The talk was always well received as it explained the fundamental concepts of the Internet and privacy of metadata in DNS and showed that it'd not been solved yet, while we are still discussing various ways with their pros and cons.

Explaining a concept people often feel they should already know about, plus the discussion of DNS privacy, always led to great feedback from the audience.

I started at a DNS management company about five years ago and had to learn a lot of this myself from the ground up.
