# macmini1 — 10.0.0.4

The **network brain + standby edge**.

- **OS:** Debian 13 Trixie (Mac Mini Late 2012, i5, 15 GB RAM)
- **Reach it:** SSH as `dietpi`

## What it does

1. **LAN DHCP** — hands out IP addresses (pool `10.0.0.100`–`.254`).
2. **DNS backup** — Pi-hole on `:53` (web `:8091`) + unbound.
3. **Standby Caddy edge** — serves sites if pi4's edge is down (LAN failover via dual-A DNS). Certs are rsync'd nightly from pi4.
4. **Authentik** — the single-sign-on (SSO) identity provider.
5. **Books & comics** — Calibre-web (books) + Komga (comics).
6. **audiocynic Ghost** — the AudioCynic blog.

## Key facts

- Docker lives under `/home/dietpi/docker/`.
- The standby edge binds `:443` only; its nginx keeps `:80`.
- The *arr stack (Sonarr/Radarr/qBit) moved to windows `.7` in Aug 2026.
