The question is a bit of a semantic one.

While having "automagical" host addressing is fairly nice, and you'll be
guaranteed to have a unique host address, let me reverse the question. How
many people memorize MAC addresses on your systems??? (If you raised your
hand, you need to seek professional help)

This becomes a question more of address manaagement than any technical
reason. We don't NEED to specify EUI-64, but if we don't then WE are
responsible for coming up with the host-address part. This may be good, so
we cam make our router the .1 (or ::1 in this case) address and things like
that.

But it's entirely up to you. Or it's specified on the lab!

Hi Group,

As I understand it, the EUI-64 argument at the end of an IPv6 address
statement will create an IPv6 address based upon the Mac address of the
interface applied.

Now what I need clarity on, is when would you not use the EUI-64 argument?
