I wonder how much more it will take before the answer to "What is my IP address?" will simply be "Look in the settings" or "Just type ip addr in the terminal".

We are so used to NAT that we don't realize how crazy it is that you essentially have to ask a stranger what's your address. It's really difficult to explain this to someone with no networking knowledge. Nothing else works this way: phone numbers, emails or postal addresses.

You don’t really have to ask a stranger - you can ask your router, in a similar way you can check the door number on your street.

If your ISP is doing a CGNAT, which are becoming more and more common, not even the router knows the public address.
