Hey, while you're picking that up from the store, would you mind buying me
one of those 300 mile/gallon carburettors?

Whether or not "address" as a generic term ought to include the concept of
"identity" is open to debate (in practise, in IPv[46], it does), but I've not
heard of anyone who says that "address" should not include the concept of
"location".

And clearly you don't know the location until the box is connected up to the
network. So the concept of having "addresses preconfigued into it" is
self-contradictory.

It might have some sort of identifier wihtout any topological significance
configured into it (just as your average box has a 48-bit IEEE address), but
that's a whole different thing; it would not be an "address".
