Pages that didn't make it into "How DNS Works"

From the Cutting Room Floor: DNS Zine Extras

Some years ago, I started drafting a zine meant to cover “everything you need to know to own a domain.” The plan was to spend a handful of pages on DNS and save the rest for domains, TLS, and email. That plan fell apart quickly: DNS turned out to need all 28 pages of the final How DNS Works zine. The other topics were cut. Instead of leaving those drafts to rot, here are the pages that didn’t make the cut.

Domain Registration

These pages cover the basic mechanics of registering a domain: what a registrar does, how the registry works, and where your money goes. They don’t make you a domain industry expert, but they fill in the business layer that DNS itself never touches.

Email and DNS

Email deserves a much longer treatment than these two pages provide. Email security is a deep topic, and honestly, my own knowledge has limits here. These pages only sketch the core DNS records that keep mail flowing and the basics of authentication. If you need to configure mail servers in production, look for a dedicated resource.

Transport Layer Security

The TLS pages are similarly shallow. They stay at the level of what a certificate is and why the chain of trust matters, without descending into handshake details or cipher suites. I might write a more thorough TLS guide later; for now this is the surface level.

That’s the lot. The full DNS story, with all the depth these topics were missing, is in the printed zine.
