1. A network system comprising:
a first device with a processor; and
a second device with a processor;
wherein the first device, in response to a request, starts an address authentication process with the second device;
wherein in the address authentication process:
the second device authenticates, at a network layer of the second device, a first network address of the first device to determine a first authenticated network address, and
the first device authenticates, at a network layer of the first device, a second network address of the second device to determine a second authenticated network address; and
wherein after the address authentication process, the first device and the second device communicate with each other, at layers above the network layer, based on the first and second authenticated network addresses.
