# 🌐 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).

## 🌍 Geographic Nodes

| Host | Location | IP | OS |
|---|---|---|---|
| `dcaprod` | 🇺🇸 US | 100.104.11.146 | Ubuntu 24.04 |
| `majortoot` | 🇺🇸 US | 100.110.197.17 | Ubuntu 24.04 |
| `majorhome` | 🇺🇸 US | 100.120.209.106 | Fedora 43 |
| `teelia` | 🇬🇧 UK | 100.120.32.69 | Ubuntu 24.04 |

## 🔗 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.
