behavior for query

	I’ve noticed that unbound (1.9.3, built from source) indicates SERVFAIL in response to a query. (unbound-host -t NS

	This same query returns a result from `dig +trace`.

	Apparently unbound is doing:

./NS           - to the root servers
com./A         - to the root servers   - to *  - to -> SERVFAIL

	Putting aside why is giving SERVFAIL, why does unbound ask the server itself what its authoritative nameserver is? Wouldn’t * be where that query should go?

	Thank you!
