<p>/etc/resolv.conf is not changed or set by BIND, as far as I know
it's got nothing to do with BIND at all.<br>
</p>
<p>IIRC Ubuntu is using 'systemd-resolved' (a local resolver with
cache) and 127.0.0.53 is the address it listens on, so you might
need to check that with 'resolvectl dns'.<br>
</p>
<p>Then check what is listening on port 53 (netstat -anp | egrep
":53.*LISTEN") on the server. <br>
</p>
<p>And also check what DNS servers your DHCP sets.</p>
