# 🌐 Network Overview
|
|
|
|
The **MajorsHouse** infrastructure is connected via a private **Tailscale** mesh network. This allows secure, peer-to-peer communication between devices across different geographic locations (US and UK) without exposing services to the public internet.
|
|
|
|
## 🏛️ Infrastructure Summary
|
|
|
|
- **Address Space:** 100.x.x.x (Tailscale CGNAT)
|
|
- **Management:** Centralized via **Ansible** (`MajorAnsible` repo)
|
|
- **Host Groupings:** Functional (web, mail, homelab, bots), OS (Fedora, Ubuntu), and Location (US, UK).
|
|
|
|

## 🔗 Tailscale Setup
|
|
|
|
Tailscale is configured as a persistent service on all nodes. Key features used include:
|
|
|
|
- **Tailscale SSH:** Enabled for secure management via Ansible.
|
|
- **MagicDNS:** Used for internal hostname resolution (e.g., `majorlab.tailscale.net`).
|
|
- **ACLs:** Managed via the Tailscale admin console to restrict cross-group communication where necessary.
