But once you’ve got them that’s the end of it they’re unlikely to change their IP addresses.
My point is it’s not like you need to be public facing, whether it would be literally millions of IP addresses that would be valid amongst a few dozen that are invalid.
I should specify - I have family of various, but typically quite low, technical skills and of various far distances apart that use the server. So it’s either walk them through getting the IP of every device they access with or driving up to about 8 hours away to do it myself.
