🌐 Network Overview

The MajorInfrastructure infrastructure is connected via a private Network Overview#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 (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
`[[majortoot	majortoot]]`	🇺🇸 US	100.110.197.17
`[[majorhome	majorhome]]`	🇺🇸 US	100.120.209.106
`[[teelia	teelia]]`	🇬🇧 UK	100.120.32.69

🔗 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.
