It's the same situation as DNSSEC.  Either it can make a secured
lookup to a parent server, it can be configured out-of-band with trust
anchors, or it can optimistically trust the first response and use it
to secure all future requests (i.e., still vulnerable to a spoofing
attack, but limiting the exposure to just the very first query).
