I have gone through the web looking at ways to do subnets for my WISP to provide customers their own IP blocks. So far all I can find information about is how mathematically subnets are divided? Not how they are "physically" programmed into a router to do it !
What I would like to do, is split a /24 network, and provide some /30 subnets to some customers!
How do I program my routers to do that ? These will be Internet IPv4 IP addresses and not private ones.
Do I just program the router WAN with the /24, and then the LAN port with a /30 ?
