Aunts and uncles and grandparents rarely have to deal with MACs. Back in the day it was still quite common to have to manually enter some IP-addresses, although it was probably not common for "non-technical" people understand anything about IPv4 adresses either. I for one to still to this day and age don't really understand IPv6 addresses, and admittedly haven't tried much. I typically disable IPv6 at the kernel because it's been nothing but trouble.
