For regular nat it’s like the pizza is able to get all the way to your house but then has no idea who to go to so somebody has to answer the door and then take the pizza from the door to the person who ordered it themselves.
And IPv6 is like the pizza delivery guy just walks right into the house up the steps into your bedroom and hands you the pizza directly.
The best part is they each have the same exact problems you’d have in real life.
Let me one up this. IPv4 NAT is like the pizza guy has to deliver to you, but you live in a gated community with a strict no visitors policy, which does not allow you to even mention what unit you’re in, and none of the addresses in the community are registered with the post office or on Google Maps either. Instead, you tell the guardhouse you want to order, and they order the pizza for you. The pizza guy delivers to the guardhouse, and the guardhouse delivers the pizza to you.
IPv6 (with firewalling) is like a normal gated community, you order the pizza and include the unit number, and the delivery driver can deliver your pizza directly, as long as the guardhouse approves.
The difference is, with NAT, the guardhouse has to both guard (firewall) and route (keep track of all deliveries, and deliver) your packages, where with IPv6, the guardhouse (firewall) only has to guard (firewall) the packages.
That’s a great analogy for carrier grade nat.

Sounds good to me
Waiting for IPv8 when the delivery guy takes a slice and feeds it to me so I don’t need to worry about greasy fingers.
The good ol’ American ipV8 motor
Nah that’s just ransomware
