the setup is a WISP (wireless ISP). Different routes to the internet may be fiber, coaxial, or even 4G although currently we are using majority fiber. The customers will use proprietary mimosa, ubiquiti style dishes at their location.
The issue arose that each customer may want their own public ipv4 address, and ARIN isn't handing out anymore. so the idea to use ipv6 fully raises the question of compatibility and having customers access everything that's already on ipv4 addresses.
