Not necessarily.  Some public networks are moving away from the ask
everyone the question, anyone can answer model. It cuts down on the
chatter, and the spoofing.  That doesn't mean you have to go to a static
provisioning model, but it does mean you have to think harder about what
you trust, what asks the questions and what answers the questions.  You
can still have a dynamic network, as long as it doesn't learn the wrong
things.
