<div><span style="font-size:10pt">I'm afraid I will now get a lecture
about wildcards I should not be using or WAN-domains that are used on a LAN,
but the point is really that I never asked for a 2nd query. There's even an
option called 'expand-hosts', but I that's not turned on.<br>

Check your /etc/resolv.conf configuration, remove any "search-suffix" or similar directive that might be in there. Also note that this is a per-client setting, it can't be centrally controlled with dnsmasq.</div>
