Changes in Addresses
This example shows that the source and destination network-layer addresses, NA and
NB, have not been changed during the whole journey. However, all four network-layer
addresses of routers Rl and R2 (Nl, N2, N3, and N4) are needed to transfer a datagram
from Alice's computer to Bob's computer.
