refused rcode is not working RPZ?

[LEE SUKMOON]

Hi all.

I am using RPZ zone. 
Below line is rpz zone file. But jifr.net is not working.


	jifr.net        CNAME .
	*.jifr.net      CNAME .

Unusual, this domain is responding with refused rcode. (from authority name server)

	$ dig @173.245.58.51 jifr.net
	
	;; global options: +cmd
	;; Got answer:
	;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 39590
	;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0
	;; WARNING: recursion requested but not available
	
	;; QUESTION SECTION:
	;jifr.net.                      IN      A
	
	;; Query time: 105 msec


I want to response NXDOMAIN.
Is it a solution this case?

Thanks.
