Buy IPv4 addresses until CGN is cheaper. If a customer has to call, and
you have to assign an IPv4 address, you have to recover the cost of that
call and address.

Meanwhile, deploy IPv6, and move toward IPv4aaS, probably 464xlat or
MAP, but your religion may vary. That way your "CGN" is an IPv6-IPv4
translator, and that's easier than managing dual-stack.
At the very least, dual-stack your web sites now, so the rest of us can
get to it without translation.
