Since you already live in a building, you can simply write “House#145” on the package and drop it into the building mailbox. Your building mail staff will pick it up and simply deliver it to the house.

However, if you live outside the building and want to send a candy box to House#145’s owner, you cannot just write “House#145” on a package and drop it off in a standard mailbox. The postman wouldn’t know which building to deliver the package to, since there are many flats with the number 145.

Instead, you will have to address the package to the building’s address, including house number 145. If you don’t include the house number, then the postman can’t understand which flat should get the package. So, in this case, the building address is the public IP address example, while the flat number is the Private IP address example.
