That's silly. Not all routers in the world do this; only some. Trucks
are not allowed to drive on some roads. I suppose the trucks are
"undrivable," then?

In English, the construction "un<foo>able" means "cannot be <foo>ed."
That's simply what it means; you can pretend it means something else, I
suppose, but then you're Humpty Dumpty redefining "glory." You have
alread agreed yourself that in some contexts, these addresses may be
routed. These contexts are not rare; they are inside every *privately*
numbered network (gee, there's that word again). Hence, they are *not*
"unroutable." They are, in some contexts, unrouted. That is not the same
thing.

The most you can correctly say in this vein, would be "publically
unroutable." Even that is suspect, since they certainly could be routed
on the public Internet; it would just be a very bad idea.

Fine. I think this horse is dead, beaten, flayed, and the buzzards have
left only bones.
