I am aware not everything uses a MAC address, Yes, as K. Hamzed said, for
example, WAN links don't use them...

I may have not expressed correctly, what I meant is:
If the used 48-bit addresses in lower layer protocols, why they did not use
48-bit routing-enabled addressing for the Internetwork layer? Not just use
the very same addresses as I may have implied (I DO NOT mean that). After
all, they were using 48-bit addresses already.
Thanks.
Saludos.
