the diagram illustrates another possible reason to use ipip encapsulation, virtual private networking.
il diagramma mostra un'altra ragione possibile per usare l'incapsulazione ip/ip: le reti private virtuali.

that machine must know how to decapsulate ipip datagrams, that is, it must also be configured with a tunnel device.
tale macchina deve sapere come de-capsulare i pacchetti ipip, in altre parole deve anch'essa essere configurata con un dispositivo tunnel.

suppose that you want to allow any host on network a to connect to any host on network b, just as if they were properly connected to the internet with a network route. ipip encapsulation will allow you to do this. note, encapsulation does not solve the problem of how you get the hosts on networks a and b to talk to any other on the internet, you still need tricks like ip masquerade for that.
l'incapsulazione ipip permette di fare questo. si noti che l'incapsulazione non risolve il problema di come far parlare le reti a e b con gli altri calcolatori di internet: per fare questo occorrono altri trucchi, come il mascheramento.
