yes. but also because of the other part of my text, which you didn't
include in your reply so i don't know whether you agreed with it or not:

in other words, the definition of "routable" depends on who you want to be
able to exchange packets with. if three networks are numbered in 10.1/16,
10.2/16, and 10.3/16, and they interconnect, then that address space is
"routable" for *some* definition of "routable". i don't think we want
to have to define, and then live with the implications of, the word

see above. dunno why you didn't read it the first time i posted it here but
i've posted it again and added some explaination. "universal" or "unique"
we know the definition of. "local" and "routable", not so much so.
