• DNS query question

    From Jeff Peng@21:1/5 to All on Wed Jun 12 05:00:01 2024
    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:
    ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 2160
    ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1

    ;; OPT PSEUDOSECTION:
    ; EDNS: version: 0, flags:; udp: 65494
    ;; QUESTION SECTION:
    ;235.84.36.104.zen.spamhaus.org. IN A

    ;; ANSWER SECTION:
    235.84.36.104.zen.spamhaus.org. 852 IN A 127.0.0.10

    ;; Query time: 0 msec
    ;; SERVER: 127.0.0.53#53(127.0.0.53)
    ;; WHEN: Wed Jun 12 02:45:16 UTC 2024
    ;; MSG SIZE rcvd: 75



    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.
