NDP should have been better designed. It still has the same problems we
had with ARP except the address pool has magnified it.
Routers should have 1) better methods for keeping ND tables low (and
maintaining only valid entries) or 2) better methods for learning valid
entries than unsolicited NDP requests.
This isn't to say the protocol itself is a waste, but it should have
taken in the concerns and developed the mitigation controls necessary as
recommendations to the implementers.
