Nah... That's short-term thinking. The future holds advanced pantries with
RFID sensors that know what is in the pantry and when they were manufactured,
what their expiration date is, etc.

And since your can of creamed corn is globally addressable, the rest
of the world knows what's in your pantry too. ;)


This definitely helps explain your misconceptions about NAT as a security tool.


Globally addressable != globally reachable.

Things can have global addresses without having global reachability. There are
these tools called access control lists and routing policies. Perhaps you've heard
of them. They can be quite useful.
