yes/no. ipv6 from what I understand, expands the ip space so everything
on the planet for the forseeable future can have its own address, hence
the IOT where you fridge takes inventory including the age of that block
of cheese in the door, and sends you a shopping list. But what if the
address you're using has 3 duplicates "out there"?
But who or what is the gatekeeper to make sure the address you choose,
supposedly at random, isn't in use someplace next door or half the
planet away? There may be some sort of an enforcement in ipv6, but I've
not heard of it. That doesn't mean it doesn't exist, just that if it
does, I've never read about it.
I'd like to read an informed discusson of how that is supposed to work.

yes, ip a and ip r for showning route. I have learn that much about ip.
