Does the following serve the use case (mentioned below)?

I've updated my .conf, results below. I'm now intending records be read from `/etc/dnsmasq_a_records` and _not_ `/etc/hosts`.

   /etc/dnsmasq.conf:
   port=[myport]
   no-resolv
   no-poll
   interface=eth8
   no-dhcp-interface=eth8
   no-hosts
   addn-hosts=/etc/dnsmasq_a_records
   domain=[mydomain.tld]

Thanks, quite good to know. What edits or additions (to the following `/etc/dnsmasq.conf` or any other file) are needed to serve this use case?

    /etc/dnsmasq.conf:
    interface=eth8
    no-dhcp-interface=eth8

Hello,

Do I need to make any edits/additions to the dnsmasq.conf below to support
the following scenario?

Ubuntu 20.04
dnsmasq 2.80

Details:

I want to provide a _minimal_ DNS server. It *only* serves a few A records
(from /etc/hosts).

A key point: I want to make sure it does NOTHING else. No
upstream-DNS-server/service connection. Any DNS requests sent to said server
outside of the /etc/hosts A-record list will fail. Further: no DHCP, tftp,
or any others. All of the other bells and whistles I do not know about: I
want them disabled, too. Just plain old proper DNS records serving and
associated error-condition handling.

Additionally, the dnsmasq-based DNS server will bind/interface/respond-to
only `eth8`.


    /etc/dnsmasq.conf:
    interface=eth8
    no-dhcp-interface=eth8

That is indeed not enough for the desired use case.
