DNS
The internet's address book for mapping names to IPs
Core Idea
DNS translates human-friendly domain names into the IP addresses networks actually use. People remember app.example.com; the network needs a numeric destination, so name resolution sits in the middle.
Why It Matters Here
Mathbong uses DNS repeatedly when explaining homelab internal domains, proxy routing, and service discovery. It is the naming layer you need before public and private paths can stay organized.
