It can't be true that the Media Access Control part of the packet is
used in the authentication as that would be destroyed by the first
IP router encountered. Authentication wouldn't be an internet
I think you have failed to realise that there is another meaning of
MAC, Message Authentication Code, a sort of sophisticated check sum.
Actually, I'm pretty sure that inclusion of the IP address in the
calculation of the Message Authentication Code is why people have
so many problems with dynamic IP addresses.
