🌐 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 (
MajorAnsiblerepo) - 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.
