That's correct. A simle "down" will only disable the
interface, but it does not remove the IP address, the
routing entry for that address, any ARP entries
associated with it etc. Otherwise it would not be
easily possible to reset an interface by a "down"-"up"
sequence.
To undo all effects of the interface configuration, you
have to "delete" all IP addresses from it. In fact, I
think you don't have to set it "down" at all. "delete"
is the important thing ("down" shouldn't hurt, though).
("destroy" is not necessary in this case. It's useful
to remove dynamically created interfaces entirely, e.g.
when using vlan or tunnel interfaces.)
BTW, your question is off-topic here, it rather belongs
to the -questions list.
Best regards
