summary: This note outlines a structured private subnet mapping scheme organized by
  location (Esteban, Phase Final NH3, Anaheim Colo), segment, VLAN, and device allocation
  (static/DHCP), with specific ranges for network purposes like Userland, Guest, DMZ,
  and Services. Key details include location octets (0, 100, 200), VLAN assignments
  (1-250), and device IP assignment rules (static 0-149, DHCP ranges per segment).
