Root hints are emitted only when asked for

This makes it possible to configure servers which serve only
locally defined zones, and also servers with multiple views.

+ROOTHINT()
+               Insert a definition of hints for reaching root servers into named.conf.
+               This is necessary if you want your DNS server to resolve foreign
+               domains; otherwise, it will only give out authoritative answers
+               for locally defined zones and forward queries. The location of the
+               file with the hints can be set by the ROOTCACHE directive (see below).

 FORWARDED(zone, ip...)
                Define a forwarding zone. All queries are forwarded to the
                specified name servers.
