You will lose the ability because *you configured the zone with
inappropriately long TTL*
no, you lose the ability only when each and every device maintains it's
own cache while TTL is normally meant for resolvers and you don't need
more than *one* trustable and redundant resolver for a whole LAN
with that *one* flush on that resolver would lead in the desired result
for the whole network and you don't need hacks like dns views for the
own LAN with a very low TTL while you don't want that for the rest of
the world
