Whitelist Manager should deploy to Billing VPS (38.68.14.188), not Ghost VPS.
This aligns with infrastructure philosophy: 'Money on Billing'
Changes:
- Updated all IP references: 64.50.188.14 → 38.68.14.188
- Updated deployment target in all docs
- Updated DNS configuration
- Updated SSH commands
- Updated SCP commands
Billing VPS is the correct location as whitelist management
is part of the subscription/billing workflow.
