I add this lines in named.conf
clients IP in this view can't resolve recursive queries.

view "localhost" {
        match-clients { ::1; };
};

view "view7" {
	....
	max-cache-ttl 0;
	zone "." {
		type forward;
		forwarders { ::1; };
		forward only;
	};
};


Trying to use
view "localhost" {
        match-clients { ::1; };
      zone "." {
              type hint;
              file "named.root";
      };
};

has the same result.
