# DNS – Basics

This page is for generic DNS concepts I reuse across projects.

## Scope

- What DNS does (names → IPs).
- Difference between public DNS and internal DNS.
- Common record types (A, AAAA, CNAME, etc.).

## Notes / TODO

- Add examples with public domains.
- Explain how internal `.lan` domains fit into this picture.

For my concrete home server DNS setup, see:
