Hello list,

I have made a successful query in one of my VPS as the following.

~$ dig 235.84.36.104.zen.spamhaus.org

; <<>> DiG 9.16.48-Ubuntu <<>> 235.84.36.104.zen.spamhaus.org
;; global options: +cmd
;; Got answer:

But, the same query wouldn't success in another VPS as follows.

$ dig 235.84.36.104.zen.spamhaus.org

; <<>> DiG 9.16.1-Ubuntu <<>> 235.84.36.104.zen.spamhaus.org

The returned result is "NXDOMAIN".

Both nodes use systemd-resolve as DNS subresolver.

Do you know what's the reason behind this?

Thanks.
