Hello
I have two debian boxes, one is running unbound for dns resolver,
another is running systemd-resolve.
As you see the first,
udp 0 0 127.0.0.1:53 0.0.0.0:*
290152/unbound
The second,
udp 0 0 127.0.0.53:53 0.0.0.0:*
268/systemd-resolve
Checking for RBL on first node is successful:
$ dig 17.39.33.194.zen.spamhaus.org +short
127.0.0.3
But second is not:
$ dig 17.39.33.194.zen.spamhaus.org
; <<>> DiG 9.16.1-Ubuntu <<>> 17.39.33.194.zen.spamhaus.org

Can you tell me why?
Thank you.
