+# 🌐 Network Overview
+
+The **[[MajorInfrastructure|MajorsHouse]]** infrastructure is connected via a private **[[Network Overview#Tailscale|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 **[[Network Overview#Ansible|Ansible]]** (`MajorAnsible` repo)
+- **Host Groupings:** Functional (web, mail, homelab, bots), OS (Fedora, Ubuntu), and Location (US, UK).
+
+## 🌍 Geographic Nodes
+
+| Host | Location | IP | OS |
+|---|---|---|---|
+| `[[dca|dca]]` | 🇺🇸 US | 100.104.11.146 | Ubuntu 24.04 |
+| `[[majortoot|majortoot]]` | 🇺🇸 US | 100.110.197.17 | Ubuntu 24.04 |
+| `[[majorhome|majorhome]]` | 🇺🇸 US | 100.120.209.106 | Fedora 43 |
+| `[[teelia|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.
